The Russian Ministry of Transport has ordered an
oblique icebreaker tug which will be assembled by
two shipbuilders, both of which fall under the
auspices of the Russian state-owned ship construction
specialist United Shipbuilding Corporation. Yantar
JSC Shipyard based in Kalingrad, Russia will
construct the hull, and Arctech Helsinki Shipyard in
Finland will be responsible for finalising the vessel.
The vessel has been built to design Aker designer
Aker Arctic’s ARC-100 specifications. One of the
76.4m newbuild tug’s unique features will be the
incorporation of an asymmetric hull into its design,
enabling icebreaking sideways.

Numerical approaches to hydroacoustic modelling are
a relatively new area of research, and different
techniques are still being developed. This study forms
a part of a larger project aiming to design a numerical
noise prediction model which can be used to predict
the noise of a new build vessel to a suitable degree of
accuracy, in the design stages. The investigations
discussed inform how the final model will work, and
what will be incorporated in it, and also the levels of
error to be expected when using alternative
approaches. The resulting model should be reliable
and provide suitably accurate results, whilst
minimising computational time and complexity, and
hence cost. This work is carried out using CDAdapco's StarCCM+ CFD package, which has a builtin acoustic model, in the form of the FfowcsWilliams Hawkings (F-WH) equation. The F-WH
equation uses generalized functions to extend the
application of Lighthill's Acoustic Analogy, which is
originally used to predict the aerodynamic noise
generated by rotating bodies such as helicopter rotors
and fan blades. More recently this equation has also
been applied to operations in other fluids, namely
water, for the noise generated by marine propellers.
In situations where detailed data on the turbulent
phenomena in the near-field can be obtained, the FWH equation can also be used for broadband noise
prediction.

The National Maritime Research Institute (NMRI) in
Japan has been investigating twin-skeg ships which
can contribute to meeting the IMO Energy Efficiency
Design Index regulations by reducing emissions. One
representative hull form is the MS791, a 4,000
twenty-foot equivalent unit (TEU) twin-skeg
container ship with an electrical propulsion system
supported by two off-centred podded propulsors.
Such a configuration makes it possible to search the
optimal location of the propeller to minimize
effective wake coefficient 1-wT and delivered power
PD as well as to maximize hull efficiency ηH. In
terms of hull design, podded propulsors mean that
skegs are free from propeller shafts which means that
their geometrical design would be much more flexible
than those of conventional twin-skeg ships. In order
to take this advantage, understanding the relationship
between skeg geometry and resistance/selfpropulsion/local flow characteristics of the ship
would be quite important for better hull design. The
objective of this study is to analyse the resistance and
self-propulsion characteristics of MS791 depending
on different skeg geometries and to obtain useful
information for further investigation of twin-skeg
ships with podded propulsors. Viscous Computational
Fluid Dynamics (CFD) simulations for towed and
self-propelled conditions of MS791 are performed
using Reynolds Averaged Navier-Stokes (RANS)
solver SURF ver.6.44 (Hino 1997) developed by the
NMRI CFD research group.

This paper reviews the theory and methodology
developed to cope with the matching optimisation of
the ship propulsion system and hull. The recent
advancements on the strip theory to forecast hull
deflection under various wave loads, and the impact
of the hull deformation on the propulsion shaft line
are discussed. The advantages and shortcomings of
traditional shafting alignment techniques are
reviewed and illustrated through examples.
Applications and the state of-the-art in advanced
shafting dynamic alignment are also reviewed.
Finally, several main areas for future development in
this field are discussed. These include development of
the precise modelling theory of a large ship
propulsion system under uncertainty, the coupled
dynamic modelling method for a large ship
propulsion system and hull deflection, and the
optimisation database for the coupling design of the
propulsion system and ship type.

A new generation of 35000 DWT handy-size bulk
carrier design, named Seahorse 35 (SH35) was
introduced in 2008. The SH35 was developed in close
cooperation with bulk carrier charterers and
operators, with focus on economical and efficient
cargo handling, loading flexibility, safety,
environmental and maintenance friendliness and low
operational cost. Since the SH35 was developed the
market situation has changed dramatically, calling for
revisiting of the design with main focus on fuel oil
efficiency and energy saving, and not least fulfillment
of the latest IMO EEDI requirements. The objectives
of this paper are to present the specific design
changes and improvements, including: hull lines
evaluation by application of CFD codes; alternatives
of main engine/propeller RPM selection; propellers
re-design to suit variable main engines data;
application of energy saving devices (Mewis Duct by

very challenging projects from the view point of
utilized technologies. This paper introduces some
innovative ideas developed by these two projects. The
objective of the ZEUS project is to obtain the
maximum energy efficiency by introducing a new
idea such as a reaction pod system It can be said that
the project aims at the final goal of ultimate ship hull
form in the future. On the contrary, the NOAH
project is aiming to achieve the ideal ship space and
arrangement for the purpose of transportation without
excessive power increment. The shape of hull is
almost a box like NOAH’s Ark. In order to improve
EEDI for this type of vessel, several new ideas will be
introduced. Here, boundary layer suction and Gate

Malta, E.B., Nogueira, M.C., Et al
English
This paper aims at contributing to the field of ship
design by introducing new systematic variation
methods for ship hull forms. Hull form design is
generally carried out in two stages. The first is the
global variation considering the sectional area curve.
Because the geometric properties of a sectional area
curve have a decisive effect on the global
hydrodynamic properties of ships, the design of a
sectional area curve that satisfies various global
design conditions, e.g., the displacement, longitudinal
centre of buoyancy, etc., is important in the initial
hull form design stage. The second stage involves the
local design of section forms. Section forms affect the
local hydrodynamic properties, e.g., the local pressure
in the fore- and aftbody. This paper deals with a new
method for the systematic variation of sectional area
curves. The longitudinal volume distribution of a ship
depends on the sectional area curve, which can
geometrically be controlled using parametric
variation and a variation that uses the modification
function. Based on these methods, we suggest a more
generalized method in connection with the derivation
of the lines for a new design compared to those for
similar ships. This is the so-called the volumetric
balanced variation method for ship forms using a Bspline modification function and an optimisation
technique. In this paper the global geometric
properties of hull forms are totally controlled by the
form parameters. The authors describe the new
method and some application examples in detail.
Calculus of variations
Hull form
Ship design
In order to design the hull shape of a compressed
natural gas ship (CNG), a parametric model was
integrated with forward resistance and seakeeping
commercial codes. This integration allowed dynamic
results analysis using only a program interface with
external codes experimentally verified. With regard
to motions in waves, potential and strip method were
used to evaluate the response amplitude operator of
the hull forms in different conditions (with/without
forward speed). The seakeeping has been defined
through acceleration and comfort indices based on
spectral analysis.
The forward resistance was
determined using nonlinear potential method for the
wave resistance and finite volume method without
free surface effect for the viscous resistance. Both
numerical models were validated with results
achieved in a towing tank. The evaluation of some
design output parameters, generated with the
parametric model, assist to determine which variables
influence the most CNG ship forward resistance and
seakeeping. The same methodology can be applied in
other types of hull shape designs.

This paper presents a new method for the generation
of an adaptive topologically correct triangular mesh
on parametric surfaces. The level of approximation is
controlled through a given tolerance resulting into a
density of triangles that increases with the local
curvature of the surface. The surface is subdivided in
the parametric domain by a recursive algorithm which
simultaneously stores the sequence of operations into
a binary space partitioning tree data structure. To
each interior edge defined by two or more vertices
correspond always only two faces.

The potential of passive design to reduce the
environmental footprint of luxury platforms
within the marine industry.

McCarten, S., Kvilums, C.
English
Passive design is the use of the natural environment
to passively cool, heat, ventilate and light a building
without significant energy use, whilst improving the
users experience and well-being. Conventionally this
is achieved through RV AC systems, which require
709
high grade energy to deliver comfortable conditions.
In the 21st century, concerns about the energy
resources required to support the growing population
has resulted in RV AC design practices within the
building industry being replaced by passive design
principles. As buildings constitute 41% of Europe's
total energy consumption, the EU energy
performance directives states that all new buildings
built after 31st December 2016 will have to produce
as much energy as they consume, which can be
achieved through passive design. Similar concerns
have led to the implementation of the Energy
Efficiency Design Index by the IMO, which signifies
the arrival of Ecological Accounting (EA) to the
marine industry. EA applies metrics to sustainability
and drives forward design innovation to reduce
energy consumption, providing ecological and
economic benefits to the users, designers and yards,
by encouraging whole systems analysis. Transfer of
Innovation of passive design from architecture to the
marine industry, would empower designers and yards
to meet this new legislation, in terms of RV AC
systems, which contribute to the greatest portion of
energy consumption of auxiliary loads, onboard
conventional vessels. This paper discusses
the potential of passive design within the marine
industry and the emerging need for design
tools to allow passive design to become an intrinsic
part of the marine design work flow. Thus aiding the
industry to meet the needs of future legislation, and
the developing luxury value perception of the owners.
Whilst lowering the operational complexity the
design should aim to be of higher efficiency in terms
of its propulsion, compared to its rivals, and with
lower energy consumption at the point of use (hotel
and auxiliary loads). The design proposal addresses
the gap in the market for luxury, performance
orientated vessels and blend ecological technologies
that work in favour of the client and also benefit the
environment. The vessel is equipped for weekends or
small holidays, in coastal areas around the Bahamas,
Caribbean Sea, Dominican Republic, and Cuba, but
also be sensitive to the surrounding Eco tones. The
vessel is powered by a self-trimming rigid wing. The
use of tubercles on the leading edge of the yacht's
mast was supported by scale model wind tunnel
testing as an integral part of the design research. This
biomimetic allowed the mast to be of a greater
diameter, without increasing the aerodynamic drag
and thus leading to a greater exhaust aperture which
facilitated the stack effect of the natural ventilation
system. The choice of a rigid wing was not purely a
technical one but also that of usability and speed.
Whilst a rigid wing is easier to operate and selftrimming it also removes much of the shrouds and
supports that a conventional sail may require. Also
decreasing the size of the crew quarters leading to
more space for passengers and more autonomy for the
aging user. Supported by 19, 80watt solar cells to
support auxiliary systems, "Logos" has complete
energy autonomy and the silent luxury of rigid wing
technology.

The cruise industry has become one of the fastest
growing tourism sectors. Growth in popularity has
changed the luxury design meaning of cruising from
its elitist beginnings into something more accessible
and less exclusive. This design proposal challenges
perceptions of exclusivity in the American cruise
market by using Design-Driven Innovation to create a
'technological epiphany', a new market between
luxury cruising and superyacht charter. The design
proposal consists of a main entertainment vessel
(cruise liner) acting as a mother ship, which
transports SWATH floating apartments to various
destination around the Caribbean. Where they are
launched and later recovered, operating on the same
principle as Dockwise yacht transporters. The
SWATH floating apartments offer clients the
freedom, luxury and privacy normally associated with
superyachts. When docked with the mother ship the
floating apartments are fully integrated into the
interior design of the mother ship. The interior design
proposals for both the mother ship and floating
apartments have been informed by the cultural
specificity of luxury in the American market.

Self-righting craft basic principles and design
requirements.
RINA Transactions - IJSCT, v 155 part B1, JanuaryJune 2013 http://www.rina.org.uk/ijsct.html
Thatcher, K.C.
English
Records show that the naval architecture of selfrighting has been known and understood for at least
two hundred years. For much of this time its
application was limited to small, shore based, rescue
boats, but the past few decades have seen the
provision of self-righting capability widen into a
diverse range of craft from offshore standby vessels
to trans-ocean rowing boats. Whatever the size and
use, the aim is always the same to provide safe
refuge for the crew by incorporating a mechanism
whereby the vessel will return upright following a
knockdown or capsize.
Despite this growing
popularity, self-righting vessel design is still viewed
by some naval architects with suspicion. The purpose
of this paper is to provide a background to selfrighting methods and basic guidance on design,
testing and outfit requirements. Although much of
the content has been based on the author’s experience
with rescue craft, it should be noted that the
principles and techniques described are applicable to
all types of vessel.

The objective of this research is to find a new rapid
design method for obtaining fairness hull surface
based on NURBS. Instead of depending on the
conventional prototype, attention is focused on
extracting the design parameters which represent the
characteristics of the hull. The energy optimisation
method is proposed to get the expression of the hull
line with NURBS, using design parameters as design
variables and least sum of curvature square of hull
curves as optimisation object. The basic shape feature
of hull curves can be adjusted under the constraint
related to interpolation points, derivative vectors,
curvatures, areas and centroid points. In this way,
711
fairness of the hull surface is ensured. One successful
example is given in order to verify the feasibility and
practicality of this method.

A hull surface transformation method based on
fairing differential equation is developed in this
paper. The hull form transformation function, which
satisfies both the fairing differential equation and the
constrain conditions of the design, is constructed
according to design requirements of the hull surface
for different design tasks. Transforming the hull
surface based on NURBS with the hull form
transformation function is realized with this method.
It is proved that the transformation will not change
C2 continuity of the hull surface. As examples of
application, transformation functions for local
modification, global transformation and UV degree
transformation of the hull surface are presented. The
method is proved to be practicable and can be used in
engineering by applying it to an oil tanker.

Parameterized modelling and modifying ship lines
play a very critical role to realize automatic
optimisation of ship lines based on CFD. This paper
proposes a new method to modify hull surfaces by the
combined function, which fully takes advantage of
both methods of modifying the hull surface, i.e. the
method based on morphing function and the method
based on global transformation function, thus large
712
range transformation is achieved and the smoothness
of the ship surface is ensured. Optimisation of ship
lines for a 1300TEU container ship was successfully
carried out with this method combined with CFD
technology and optimisation algorithm, and
eventually the ship hull form with the best
performance was obtained. This result indicates that it
is feasible and certainly valuable to modify hull
surfaces with this method based on the combined
function proposed in the paper.

Mitsubishi Heavy Industries (MHI) has completed the
development and received firm orders for a newgeneration LNG carrier design marking an
evolutionary advance for LNG carriers adopting the
Moss-Rosenberg cargo containment system well
proven for robustness and reliability. The product
name SAYAENDO, or peapod in Japanese, aptly
describes the continuous weather cover for the cargo
tanks that is integrated with the ship’s hull,
constituting a visual and conceptual distinction from
the ubiquitous hemispherical covers found on
conventional Moss LNGCs. This new configuration
benefits from greater structural efficiency thus
enabling size and weight reductions, resulting in
improvements in fuel consumption and operating
economies. This paper presents how state-of-the-art
engineering verification methodologies were applied
to validate the new design to meet the stringent
technical, regulatory and safety requirements of the
LNG shipping industry, as well as the design of
SAYAENDO itself.
Firstly, structural design
analysis using MHI-DILAM is described. MHIDILAM is an advanced structural assessment
approach developed by MHI, applied to verification
of yield and buckling limit states with design waves
and full stochastic analysis for fatigue strength
performed on a whole ship model incorporating loads

Secondly, independent structural design verification
as part of classification requirements or in support of

insight into the SAYAENDO’s unique hull concept
highlighting those aspects that were considered as
part of the validation of the overall design and safety
philosophy.
Examples of how risk assessment
methods were employed to evaluate unconventional
arrangements are also introduced. Finally, the main
characteristics of 155k-m3 LNGC are described, this

The shipbuilding industry in Europe is in crisis due to
the recent economic recession and competition from
countries with low labour costs. Greek shipyards have
been forced to make a series of structural changes
which have resulted in lower employment levels.
Although these changes were gradually creating the
conditions for shipyards profitably to re-enter
international markets, the current economic crisis and
the consequences to the shipping sector have created
major problems to the shipyards employment. Perama
shiprepair zone, an industrial zone mainly consisted
from SMEs (small and medium enterprises) in
shipbuilding and ship repairing sector, has faced
major problem for its survivability. In this article, a
new approach is presented. Green offshore structures
are expected to create competitive advantages in the
zone and be a way to utilize available facilities and
recover from the existing situation. International
experience through case studies is presented followed
by economic and technical feasibility for offshore
wind turbines construction and wave energy devices
in shipyards. Finally, a general model shows that
sustainable development is possible and shipyards
have the adaptability and resources required for the
production of renewable energy offshore structures.

Electrical design of a 17 MW class HTS motor for

A superconducting motor shows several advantages,
such as smaller size and higher efficiency, over a
conventional motor, especially utilized in ship
propulsion applications. However, the size reduction
merit appears for large capacity, more than several
MW. The authors develop a large capacity
synchronous motor with a rotating high-temperature
superconducting (HTS) coil, which is aimed to be
utilized for ship propulsion, so it has a low rotating
speed of about 200 rpm. The ship propulsion motor
must generate high electromagnetic torque instead of
low speed. Therefore, the rotor (field) coils have to
generate a large magnetic flux that results in a large
amount of expensive HTS conductor for the field coil.
In this paper a 17 MW HTS motor for ship propulsion
is designed with a cost-effective method because the
HTS conductor cost is a critical factor in the
construction of an HTS motor. Unlike conventional
rotating machines, the superconducting motor
consists of an iron-coreless structure. Most
conventional motors can be designed with small error
based on two-dimensional magnetic field analysis.
However, the superconducting motor shows an even
larger error between the two- and three-dimensional
based designs. Thus, in order to improve the design
accuracy, the authors have calculated the back
electromotive force (EMF) using 3D magnetic field
analysis. An output performance evaluation has also
been carried out to obtain a design with higher
efficiency.

Marine engines represent a significant contribution to
global emissions. In order to overcome this problem,
a great attention was given to reduce their exhaust
emissions in the last years, and marine engines have
to adapt to regional, national and international
restrictions. In this regard, the purpose of this paper is
to develop a numerical model to study NOx (nitrogen
oxides) and other pollutants in engines. EGR and
water addition were studied too as measures to reduce
NOx. The main advantage of this study is that it
provides a cheap and fast method to analyse
emissions, contrary to experimental setups which are
too expensive and laborious. Particularly, a
commercial marine engine was analysed and
validated with experimental data. Results showed that

Concern over the vulnerability of Liquefied Natural
Gas (LNG) carriers entering US ports has increased
in recent years. Several studies have weighed in on
the potential consequences resulting from large
accidental or intentionally caused spills. One specific
concern was that LNG cargo tank insulation could be
susceptible to high-temperature thermal degradation
in the event of a large-scale LNG fire. This could
result in cascading damage of other cargo tanks not
originally damaged during an initial accident or

composition acquires special importance in longduration trips and is essential for importers, exporters,
shipments, etc., to know the 'quality' of the LNG that
is to be unloaded in the regasification terminal, so
that LNG meets quality specifications of each
country. In order to solve the existing lack of
knowledge on the behaviour of LNG during ship
transportation, a group of European gas companies
has developed a useful tool called MOLAS for
predicting changes in LNG composition at any time
during the voyage and just at the end. MOLAS
application contains two different approaches. A
physical model based on mass balances and
equilibrium state between liquid and vapour phases,
and an 'intelligent' model, based on artificial neural
networks that takes into account nonlinear
relationship among the variables involved. MOLAS
has been tried out comprehensively and an average
error in Wobbe Index and Gross Calorific Value less
than 0.20% and 0.30% has been obtained
respectively. The results provided by MOLAS, can
help terminal operators to manage regasification
plants in a more safe and efficient manner and can
help engineers and technicians to take, in advance,
necessary actions on natural gas so that it can comply
with required quality specifications.
The Condition Based Maintenance (CBM) method
proposed is based on statistical processing of signals
and consists of applying control charts to monitor
system condition in the context of CBM, aiming at
reduction of failure rate, increasing both reliability
and availability of maritime equipment. Control
charts, being a primary tool for control and
monitoring of processes, can be used to control
variables such as oil pressure and temperature. This
will allow the authors to distinguish between common
and special causes of data variation. With this
methodology the authors intend, initially, to estimate
the statistical parameters of signals by applying the
Standard Deviation Chart. In a second state, for
monitoring and modelling the behaviour of
equipment, the modified CUSUM (Cumulative Sum)
and ERMA (Exponentially Weighted Moving
Average) charts were applied.

Nowadays, the most prominent risk assessment
techniques are founded on the values of measuring
and controlling the frequency and the consequences
of risks in order to assure an “acceptable level” of
“safeness” mainly in the lines of environmental,
health and hygiene and port product issues. This
paper initially introduces risk assessment approaches
within the emerging role of ports. Thereafter, it
qualitatively assesses their potential for ports by
discussing issues challenging every safety and
security approach within the maritime industry such
ABSTRACTS
as pro-activeness, organisation, transparency, costeffectiveness and, when possible, calibration to
specific experiences. Moreover, an empirical study
was conducted in order to provide evidence for
formal risk assessment for safety and security in the
main Greek port container terminals of Piraeus and
Thessaloniki. The empirical research is based on indepth
semi-structured
interviews
with
the
administrations of container terminals. The results
include important findings, regarding the likelihood
of appearance of certain risks and their perceived
severity in Greek container terminals. The collected
answers and their analysis are also important for
confirming the suggested theoretical formal risk
assessment framework for ports.

This paper describes the use of a numerical and
physical modelling study in the design of large
breakwaters for a new port and dry dock complex on
the southern coast of Oman. The numerical modelling
was carried out to optimise the entrance channel
layout with respect to wave penetration into the port
and to refine design conditions for the sizing of the
primary armour on the breakwaters. Wave conditions
inside and outside of the port have been assessed
using the 2-dimensional numerical wave penetration
model MIKE21 EMS (Elliptic Mild-Slope). As part
of the design process, 3D physical modelling studies
were also undertaken at Delft Hydraulics in the
Netherlands to confirm the stability of the armour on
the trunk and roundhead of the breakwaters and to
verify the influence of the deep approach channel on
stability. The opportunity was taken to extend the
physical model tests to assess the influence of the
deep channel on wave penetration through the port
entrance. The paper focuses on the influence of the

the port and compares the results from the numerical

economic situation and the global container market
have improved slightly after the 2008 world
economic crises. Egyptian container terminals are
important to serve the world liner services in

considered the leading country in Africa and the 18th
worldwide in serving the liner markets. Alexandria

throughput. The analysis of Alexandria container
terminal performance indicators from 2007 to 2011
shows a slightly progressive trend. Selected
indicators, reflecting production, productivity,
utilization and service measures, were used according
to the available data. Terminal production shows a
slight increasing demand concerning number of
vessels and TEUs (Twenty Equivalent Units).
Furthermore,
productivity
indicators
proved
remarkable development in moves per working hours
rather than moves per hours in port, deducing lack of
port services accompanying cargo handling.
Moreover, Utilization measurements show the
terminal occupancy ratio fluctuating from 45% to

measures show progress in vessels turnaround time,
while long wasted time consumed in processes rather

Some new innovative constructions and technologies
for improvement of port structures are worked out
and discussed. The aims of innovations are to
increase structure reliability, to decrease construction
and maintenance costs, to simplify technology and
cost of building. For these purposes either some main
bearing elements or structures in whole are modified
or improved. In particular different improved
waterfront constructions as well as retaining walls
and coastal protection (gravity, piled, sheet piling,
etc.) for use in various soil conditions are outlined.
One of them incorporates trapezoidal blocks forming
columns, each block in the column contacts the others
either with smaller or larger bases. Another design
incorporates blocks that are constructed with holes
ran through the centres of gravity of the blocks. Rigid
720
cylinder element running through the holes of several
adjacent blocks allows them to be joined forming
large size units. The structure consisting of wedge
form retaining wall is original but simple to construct.
Some new designs based on perfection of sheet-piling
walls (sheet piles with curvilinear cross-section
having a form of semi-rings) are proposed for
different applications. Proposals on modernization of
some traditional structures and technologies are
discussed.

The aim of this paper is to investigate how bound and
free long waves and their relative components change
with respect to short wavelengths when resonance
occurs in a long and narrow rectangular harbour.
Long-period oscillations excited by bichromatic
primary waves are simulated using the Boussinesq
model. A separation procedure is proposed to
decompose the low-frequency components inside the
harbour into bound and free long waves. For
comparison, the non-resonant wave condition is also
considered. It shows that the amplitudes of bound and
free long waves and their ratio are closely related to
the short wavelengths, regardless of whether the
harbour is resonant or not. For the given harbour and
primary wave frequency ranges studied in this paper,
when the harbour is at the lowest resonant mode, the
amplitudes of bound long waves are always lower
than those of free long waves but tend to be larger
than half of the latter when the average short
wavelengths are larger than 0.66 times the harbour
length. When the harbour is non-resonant and the
average short wavelengths are larger than 0.56 times
the harbour length, the former is inclined to be larger
than the latter.

A simplified vortex model of propeller and windturbine wake.

A new vortex model of inviscid propeller and windturbine wakes is proposed based on an asymptotic
expansion of the Biot–Savart induction law to
account for the finite vortex core size. The circulation
along the blade is assumed to be constant from the
blade root to the tip approximating a turbine with
maximum power production for given operating
conditions. The model iteratively calculates the tipvortex path, allowing the wake to expand/contract
freely, and is afterward able to evaluate the velocity
field in the whole domain. The ‘roller-bearing
analogy’, proposed by Okulov and Sørensen (2010),
is used to determine the vortex core size. A
comparison of the main outcomes of the present
model with the general momentum theory is
performed in terms of the operating parameters
(namely the number of blades, the tip-speed ratio, the
blade circulation and the vortex core size),
demonstrating good agreement between the two.
Furthermore, experimental data have been compared
with the model outputs to validate the model under
real operating conditions.

The objective of this paper is to study how ship

these factors. For clarification, simulations of two

results were compared. Numerical simulations of tidal
currents, waves, and wind were applied to provide

A potential flow model is derived for a large flap-type
oscillating wave energy converter in the open ocean.
Application of Green’s integral theorem in the fluid
domain yields a hypersingular integral equation for
the jump in potential across the flap. The solution is
found via a series expansion in terms of the
Chebyshev polynomials of the second kind and even
order. Several relationships are then derived between
the hydrodynamic parameters of the system.
Comparison is made between the behaviour of the
converter in the open ocean and in a channel. The
degree of accuracy of wave tank experiments aiming
at reproducing the performance of the device in the
ABSTRACTS
open ocean is quantified. A parametric analysis of the
system is then undertaken. In particular, it is shown
that increasing the flap width has the beneficial effect
of broadening the bandwidth of the capture factor
curve. This phenomenon can be exploited in random
seas to achieve high levels of efficiency.

The evolution of two-dimensional dispersive focusing
wave groups in deep water under wind forcing and
wave breaking effects is investigated numerically and
measurements
collected
from
wind–wave
experiments are used to evaluate the numerical
simulations. Wind forcing is modelled by introducing
into the dynamic boundary condition a surface slope
coherent pressure distribution, which is expressed
through Miles shear instability theory and Jeffrey’s
sheltering model. To activate Jeffrey’s model in
simulating waves evolving under wind forcing, an air
flow separation criterion depending on wind speed
and wave steepness is proposed. Direct comparisons
of the measurements and the simulations are made by
including the wind-driven current in the simulations.
To simulate breaking waves, an eddy viscosity model
is incorporated into a system of nonlinear evolution
equations to dissipate wave energy and to predict
surface elevation after breaking. For wave groups
under no wind action, the eddy viscosity model
simulates well the energy dissipation in breaking
waves and predicts well the surface elevation after
breaking. Under the weaker wind forcing condition,
after consideration of the wind-driven current, the
numerical model produces satisfying predictions. As
the wind forcing becomes stronger, the disparity
723
between the experiments and the simulations
becomes more evident while the numerical results are
still regarded as acceptable. The relative importance
of the Miles and Jeffrey’s models for waves under
wind forcing are discussed through additional
numerical tests.

This paper reviews the existing simplified methods
for wave energy spectrum modification as the water
depth reduces. The TMA method (Bouws, 1985) is
implemented and applied with the aim of assessing
both the reduction in the available power resource
and the energy converted by a floating wave energy
converter. This method is based on the hypothesis
that the similarity principle for the saturation range of
shallow-water spectrum (Kitaigorodskii, 1975) is not
restricted to the equilibrium range, but is valid across
the entire spectrum. This hypothesis has been
proven, thus demonstrating that a finite depth
spectrum can be obtained by simply multiplying the
corresponding deep water spectrum by a function of
the angular frequency. The Pelamis machine and the
wave climatology of Figueira da Foz (Portugal) are
used as a case study.

The objective of this study is to evaluate two state of

and STWAVE. This study is especially focused on
the performance of the two models in shallow and
very shallow water. The target area considered is
Porto Ferro, which is located on the northwest coast
of Sardinia. Comparisons were made as regards to
the spatial distribution of the main wave parameters,
based on the results obtained by both models. In the
724
ABSTRACTS
time domain comparisons are made for the period 614 February 2005. A wave-rider type buoy was used
as offshore forcing source and the same nested
scheme was considered for both models to study the
wave transformation towards the shore. As a general
conclusion, besides its simplicity, a major advantage
brought by the STWAVE model is that almost no BC
effect is introduced as in SWAN. This is due to the
scheme adopted for the wave propagation along a
way ray. Nevertheless this feature represents an
advantage mainly for one computational domain
rather than in the case of nested schemes.

The influence of the environmental conditions on
wind turbine design loads for a monopole foundation
is studied by analysing the bending moment at the
tower base and blade root for various values of water
depth, tower height, pile diameter and wind
turbulence model. The main design requirements are
related to the limitation of maximum deflection at the
tower base which influences the vibration modes of
the complete structure. The analysis is done using
FAST code for wind turbines, which operated in the
time domain. The detailed effects of pile diameter,
height of tower and water depth are presented. The
study is carried out by using a 5 MW wind turbine
with a monopole foundation.

This paper shows the result of a research project with
the main objective of developing a conceptual design
of a new type of submarine electrical generator for
the exploitation of marine currents sited in
increasingly deeper waters. The proposed device can
work into the water and gets the right depth and
position only using hydrodynamic forces that allow it
to go to the surface or dive without any other help.
The generator has no fixed foundations and it is
placed on an intermediate level between the surface
and the bottom through a simple anchor system, the
entire device, including the anchor system, can be
removed without damage to the marine environment.

The objective of this work is to evaluate the wave
energy resources in two enclosed seas, the Black Sea
and the Caspian Sea. A first perspective of the wave
and wind climate in these areas is given by a medium
term analysis of some recent satellite data. This
allowed the identification of the most energetic
sectors. As a further step, wave prediction systems
based on the SWAN spectral phase averaged model
were implemented and validated in the two seas.
Comparisons carried out against remotely sensed data
show that these wave prediction systems generally
provide accurate results in terms of significant wave
heights. Finally, using the numerical wave models,
725
the spatial distribution of the wave energy was
analysed for some case studies that correspond to the
most relevant wave patterns. This work gives some
insight on the wave conditions and the wave energy
potential, in the basins of the Black and Caspian Seas.
The perspective of the development of the wave
energy devices for small amplitude waves is expected
to be very dynamic in the near future and to bring
technological breakthroughs. Thus following such
tendencies, the problem of extracting this type of
renewable energy in the Black and Caspian Seas,
most probable coupled in hybrid farms wind-waves

This paper describes a new concept of a multipurpose offshore platform as headquarters of a
wind/wave farm and fish farm. To be sited in
locations where the water depth exceeds 50m, the
proposed solution is a semi-submersible platform,
framed type, with a payload of nearly 600 metric
tons. It can be fully assembled onshore and towed to
its final location with significant commissioning cost
savings. The platform may have multiple layouts
withy dedicated areas for work on deck, cranes,
access for equipment and personnel, ration silos and
helipad. This new concept enables an efficient
development of different business areas coexisting in
the offshore environment, minimizing environmental
impact with large economic benefits in infrastructure

This paper describes an integrated system for
personnel and equipment transfer to offshore wind
turbines. The system consists of a SWATH ship with
an ample aft deck where up to 6 capsules, inverted
cone shaped, are stowed in berths. In sea states
between 1m and 3m wave height, each of these
capsules is to be moved to the wind turbine platform,
carrying up to 6 persons and 1 t of equipment, using a
shipboard crane when the ship is suitably located
alongside the wind turbine at a safe distance. The
wind turbine work platform is fitted with a 360o ring
where the capsule is to be deposited using the crane
and left during the duration of the maintenance
operations. The main benefits of this system are that
it is capable of providing access to wind turbines in
sea states up to 3m and personnel and cargo are
transferred protected inside a capsule. Costs are
relatively low as a wind farm with 200 turbines can
be serviced by 2-3 ships.

are designed aiming to match the predominant wave
period of the operational zone. The frequency
domain transfer functions are obtained, viscous roll

Moreover, analysis based on irregular seas is made
aiming to estimate the responses in a real sea state.
The results show that the designed geometrical shapes
guaranties amplitudes in roll higher than 3o for the
most common zero crossing period and the observed
significant wave height. Further, a static analysis of
the mooring system reveals that less heavy materials

floaters may be added to the mooring system in order
to further reduce the load, especially the vertical load

Floating production storage and offloading (FPSO)
facilities are used at most of the offshore oil fields
worldwide. FPSO usage is expected to grow as oil
fields move to deeper water, thus requiring the
reliability and stability of mooring wires and risers in
extreme environmental conditions. Except for the
case of predictable attack angles of external loadings,
FPSO facilities with turret single point mooring
(SPM) systems are in general use. There are two
types of turret systems: permanent systems and
disconnectable turret mooring systems. Extreme
environment criteria for permanent moorings are
usually based on a 100-year return period event. It is
common to use two or three environments including
the 100-year wave with associated wind and current,
and the 100-year wind with associated waves and
current. When fitted with a disconnectable turret
mooring system, FPSOs can be used in areas where it
is desirable to remove the production unit from the
field temporarily to prevent exposure to extreme
events such as cyclones or large icebergs. Static and
dynamic mooring analyses were performed to
evaluate the stability of a spider buoy after
disconnection from a turret during cyclone
environmental conditions.

The Baltic Sea is an enclosed body of water in which
an accident may have serious environmental and
financial consequences. The entrances to the Baltic
Sea are difficult to navigate, because the waters are
shallow and the currents are strong. The Great Belt is
the largest and the most important strait of Denmark,
connecting the Kattegat to the Baltic Sea. Across this
strait spans The Great Belt Bridge, which connects
Zealand with Funen and is one of the world’s longest
suspension bridges. The work in this paper is based
on AIS data in the vicinity of this bridge, examining
the distances between vessels while passing each
other. The bridge is a narrow passage in the Strait.
As a result, it encounters with a small distance appear
frequently, which may finally lead to a serious

This paper presents a quantitative approach to Human
Reliability Analysis (HRA) during emergency
conditions in an offshore environment. Due to the
lack of human error data for emergency conditions
most of the available HRA methodologies are based
on expert judgment techniques. Expert judgment
suffers from uncertainty and incompleteness due to
partial ignorance, which is not considered in available
techniques. Furthermore, traditional approaches
suffer from unrealistic assumptions regarding the
independence of the human factors and associated
actions. The focus of this paper is to address the issue
of handling uncertainty associated with expert
judgments with evidence theory and to represent the
dependency among the human factors and associated
actions using a Bayesian Network (BN) approach.
The Human Error Probability (HEP) during different
phases of an emergency is then assessed using a
Bayesian approach integrated with an evidence theory
approach. To understand the applicability of the
ABSTRACTS
proposed approach, results are compared with an
analytical approach: Success Likelihood Index
Methodology (SLIM). The comparative study
demonstrates that the proposed approach is effective
in assessing human error likelihood. In addition to
being simple, it possesses additional capability, such
as updating as new information becomes available
and representing complex interaction. Use of the
proposed method would provide an effective
mechanism of human reliability assessment in
hazardous operations.

It is very common to see a collision at sea between an
anchored vessel and another vessel underway. When
determining liability between an anchored vessel and
the other vessel in a collision, the anchored vessel
may usually be held not liable, especially in the
judgement of the maritime authority or maritime
court. The author discusses some issues in respect of
a collision between an anchored vessel and other
vessels under the International Regulations for
Preventing Collision at Sea, adopted by the
International Maritime Organization in 1972

The failure data available for power, navigation,
propulsion and steering systems onboard ships are
often accompanied with a high degree of uncertainty.
For this reason the use of conventional probabilistic
risk assessment methods may not be well suited. The
approach described uses fault tree analysis to
calculate the fuzzy probability of the systems failure.
The risks associated with failure events are
determined by combining their fuzzy probability and
possible fuzzy consequences to produce a fuzzy risk
ranking. The parameters of fuzzy consequences
model and the total risk ranking comprising
grounding risk of seaworthy vessel and defective

A risk assessment is performed for the approach
manoeuvres of an LNG vessel to berth and moor at a
floating liquefied natural gas platform. In order to
fulfil that objective, an identification of the
procedures of berthing and mooring in good and bad
weather is performed. Based on this analysis several
hazards are identified. These hazards are mainly a
result of human errors or equipment failures and are

then quantified based on expert opinion in terms of
frequency of occurrence and potential consequences.
These procedures correspond to the first two steps of
the IMO Formal Safety Assessment. Based on the
obtained results it is possible to identify situations of
higher risk based on a predefined risk acceptance
criterion.

The purpose of this study is to develop a risk model
associated with LNG spills during the whole shipping
process, identifying their causes as well as the
corresponding operations when spills are detected.
Some of these operations take place in the LNG
terminals. The spillage frequencies occurrences are
also quantified. These activities are an inherent part
of the safety analysis procedure, employing the fault
tree technique. Both the cause identification and the
frequency quantification are based on data collected
earlier (IMO, 2007).

As in every industry at risk, the human and
organisational factors constitute the main stakes for
maritime safety. Furthermore, several events at sea
have been used to develop appropriate risk models.
The investigation on maritime accidents is,
nowadays, a very important tool to identify the
problems related to human factors and can support
accident prevention and the improvement of maritime
safety. Operation of ships is full of regulations,
instructions and guidelines also addressing human
factors and safety culture to enhance safety.
However, even though the roots of a safety culture
have been established, there are still serious barriers
to the breakthrough of the safety management. One
of the most common deficiencies in the case of
maritime transport is the respective monitoring
and documentation usually lacking adequacy and
excellence. Nonetheless, the maritime are can be
exemplified from other industries where activities are
ongoing to foster and enhance safety culture.

This paper summarizes LNG ship cryogenic and fire
damage and cascading damage potential identified for
small to large LNG spills in recent research efforts
conducted from 2008 through 2011. The level of
damage and the cascading damage potential for the
different type of LNG ships is discussed for a range
of credible accidental and intentional events. The
impact of events have been evaluated for both nearshore and off-shore LNG export and import
operations. General and specific risk management
approaches that could be considered to reduce the
risks and hazards to LNG ships are presented.
Specific cascading damage and risk management
concerns, concepts, approaches, and options are
highlighted.
have examined the potential hazards from an
accidental or intentional breach of an LNG cargo tank
and the potential for cascading damage. Here,
cascading damage is defined as damage caused to the
LNG ship or cargo tanks from an initial spill that
would lead to the subsequent release of LNG from
additional cargo tanks. In 2007, the US Government
Accountability Office produced a report on LNG
research and identified several areas where additional
research was suggested. Improving the state-ofknowledge surrounding the potential for cascading
damage to LNG ships was among the most critical
needs. The study of cascading damage issues has
proven difficult primarily due to the fact that these
events require the analysis of the interaction of a
series of complex physical processes (e.g., LNG flow,
heat transfer, fire development, and structural
fracture, damage and response). Consideration of
cascading damage impacts are based on LNG vessel
structural steels being extremely brittle at LNG
temperatures (-161oC), and LNG fires generating very
high temperatures (exceeding 1000oC) that will lower
the strength of structural steels. This paper
summarizes the more recent of these studies (Kalan et
al., 2011, Figueroa et al., 2011, and Petti et al., 2011)
which explored the cryogenic and fire thermal
damage to LNG ships during a large LNG cargo tank
breach and the potential for cascading structural
damage.

In constructing a collision avoidance system, it is
important to determine the time for starting a
collision avoidance manoeuvre. Many researchers
have attempted to formulate various indices by
applying a range of techniques. Among these indices,
collision risk obtained by combining Distance to the
Closest Point of Approach (DCPA) and Time to the
Closest Point of Approach (TCPA) information with
fuzzy theory is mostly used. However, the collision
ABSTRACTS
risk has a limit, in that membership functions of
DCPA and TCPA are empirically determined. In
addition, the collision risk is not able to consider
several critical collision conditions where the target
ship fails to take appropriate actions. It is therefore
necessary to design a new concept based on logical
approaches. In this paper, a collision ratio is
proposed, which is the expected ratio of unavoidable
paths to total paths under suitably characterized
operation conditions. Total paths are determined by
considering categories such as action space and
methodology of avoidance. The International
Regulations for Preventing Collisions at Sea (1972)
and collision avoidance rules (2001) are considered to
solve the slower ship dilemma. Different methods
which are based on a constant speed model and
simulated speed model are used to calculate the
relative positions between own ship and target ship.
In the simulated speed model, fuzzy control is applied
to determination of command rudder angle. At
various encounter situations, the time histories of the
collision ratio based on the simulated speed model are
compared with those based on the constant speed
model.

When an oil-spill accident occurs at sea, it causes
tremendous economic loss and environmental

predicting the amount of oil-leaking is one of the
most important things for quick response and decision
making in the early stage of the accident. In this
study, numerical investigation on the oil-leaking
phenomena from a two-dimensional damaged tank
was carried out to predict the amount of oil leaking
from a leakage hole of a rectangular tank by using the
PNU-MPS
(Pusan-National-University-modified

The purpose of this paper is to investigate reasonable

environmental formal safety assessment (FSA). In
this study a statistical analysis of oil spill data was
carried out based on the report of International Oil
Pollution Compensation Funds. According to the
statistical study of actual oil spill from tankers, it is
found that collisions and groundings are the most
probable causes of the oil spills from tankers.
Probability distributions of costs of oil spill and oil
spill amount are investigated, and a non-linear
regression formula between costs of oil spills and oil
spill weight are derived. Using the regression
formula, an oil spill weight dependent CATSthr (Cost
of Averting a Ton of oil Spilt) is proposed. Moreover
in order to apply the weight dependent CATSthr to
cost benefit analysis (CBA), a new cost-effective
criterion is newly proposed with considering its
concrete application to environmental FSA.

Most of the Australian commercial fishing fleet is
very dependent on petroleum fuel as an energy
source. To identify ways of saving fuel and reducing
the associated expense a three tiered energy audit
process for fishing vessels was developed and
subsequently implemented. Seven vessels, including
fish and prawn (shrimp) trawlers, as well as fish and
crayfish pot/trap vessels, were audited to a Level 1 or
2 standard.
The auditing process exposed: a
reluctance by many fishing companies to undertake
an audit; inadequate record keeping by some
companies to enable an audit to be undertaken;
insufficient qualified technical people to provide the
necessary input on technologically based upgrades;
and difficulty in determining accurate payback
periods for many of the potential upgrades due to a
paucity of relevant technical data. The audit results
showed that rising fuel prices are less likely to impact
on passive fishing methods (diesel cost/revenue
ranged from 0.09-0.17 for the passive methods cf.
0.18-0.34 for the active methods), and such methods
can yield comparable levels of seafood production per
unit of fuel to active methods (with catch (kg)/fuel
used (L) ranging from 0.40-1.07 cf. 0.19-1.28 for
passive and active fishing methods respectively). A
range of upgrade/improvement options are presented
in summarised form for one of the audited fish
trawlers, together with the outcome of several
subsequent upgrades recommended in the report.
The aim of this paper is the development of a riskinformed decision tool for the optimal missionoriented routing of ships. The strength of the hull is
investigated by modelling the midship section with
finite elements and by analysing different damage
levels depending on the propagation of plastification
throughout the section. Vertical and horizontal
flexural interaction is investigated. Uncertainties
associated with geometry and material properties are
accounted for by means of the implementation of the
response surface method. Load effects are evaluated
using strip theory. Reliability analysis is performed
for several ship operational conditions and
considering four different limit states. Then, risk is
assessed by including the direct losses associated with
five investigated damage states. The effects of
corrosion on aged ships are included in the proposed
approach. Polar representation of load effects,
reliability, and direct risk are presented for a large
spectrum of operational conditions. Finally, the
optimal routing of ships is obtained by minimizing
both the estimated time of arrival and the expected
direct risk, which are clearly conflicting objectives.
The optimisation process provides feasible solutions
belonging to the Pareto front. The proposed approach
is applied to a Joint High Speed Sealift.

Short Sea Shipping is the name given to the use of
ships to transport cargo within a country, or between
neighbouring countries.
The European Union
considers all intra-European sea transport as Short
Sea Shipping, and has defined its efficient use as
strategic goal. This form of transport has many
recognized advantages over rail and road, but suffers
from lack of flexibility. This paper proposes a
logistic model for short sea shipping that greatly
increases flexibility, and that may reduce costs
substantially. The model is described and formalized,
and a generic algorithm based optimisation procedure
is presented, to assign cargo and routes to each ship,
as well as provide stowage plans. The proposed
method is used on a small problem that illustrates the
advantages that can be obtained.

lag between the orders from ships and the actions

factors: tugboat motion, engine power and direction,
but the authors research shows that there are “Nonstandard” special manoeuvring orders other than
those “standardized”, which causes such problems as
a gap in perception between pilots and tugboat

shipping markets from one that was dominated by

the market share stability of individual steamship
lines. The approach is to estimate a model of market
share variation in U.S. liner shipping markets and
compare the results under the two separate regulatory
regimes.
The use of “Standard Manoeuvring Orders” for

The potential growth of short sea shipping motivated
the study of a methodology to be used as a decision
support tool in determining the composition of the
fleet that is required for a given market scenario. The
model allows both the parameters regarding the
demand of markets and the characteristics of the fleet
to be varied so as to evaluate the sensitivity of the
response. The tool also provides enough information
to prepare the fleet deployment, establishing its routes
and scales in the ports of a particular scenario. The
adopted methodology may be divided in two parts,
the first one being related to the generation of all
feasible routes, with parameters specific to each route
for each vessel. The second part is the development
of a linear programming model to minimize the total
cost of the shipping operation. The models were
structured to present three main points: the evaluation
of the fleet for each vessel class; the optimal route for
each vessel and the frequency in each port. To
provide a supporting base towards the mandatory
validation, a fictitious case study is presented and
several sensitivity analyses are developed to test the
model’s robustness and coherence.

view of the Human Factors discipline is being
superseded by a systems-based approach which

environment and makes little or no attempt to
separate the human, machine and task environment.
This socio-technical systems approach complements
the latest thinking from cognitive science which
regards the human use of technological artefacts as a
joint cognitive system. People work in distributed
teams, who all have a slightly different perspective of
the system; the tools that they use serve as 'cognitive
amplifiers' to enhance human abilities. This brief
overview begins by examining the operation of ships
in the context of a socio-technical system and extends
this to describe them as a joint cognitive system. This
is illustrated using the contrasting tasks of navigating
a high speed craft and fighting a Type 23 frigate. In
both cases, however, the information underpinning
situation awareness belongs to neither the crew nor
the vessel alone. It is an interaction between the
technology and the teams on board.

In these circumstances the choice is between meeting
the original estimated time of arrival (ETA) and then
let the ship ride at anchor or slowing down the ship in
order to adjust the arrival to the actually needed time
window. The latter option is called "Virtual Arrival"
because it consists of applying a speed reduction that
fits the new time for port operations instead of
arriving at the original ETA. The purpose of this

Fuel consumption has a significant effect on the
operating costs of inland vessels. It is possible to
estimate fuel consumption for the prescribed
operating conditions on the basis of the propulsion
system’s parameters. The method described in this
paper is based on a mathematical model of the
hydrodynamic interactions in the propulsion system
of the inland vessel. The power demand for the given
operating conditions is calculated using the vessel and
propulsion system parameters as the input data. Then
fuel consumption is determined on the basis of the
engine characteristics. The method allows one to
analyse the effect of individual parameters on the
operation of the propulsion system. This paper
presents the results of tests of the newly upgraded
propulsion system of the Bizon III push tug. The
upgrade included the replacement of the main engines
and a change of the propeller pitch. The presented
analysis concerns the effect of propeller pitch on fuel
consumption in given operating conditions. The
influence of other propeller parameters is also
analysed. A range of operation in which the main
engines are free from overload was determined for
the upgraded propulsion system. Then the operating
parameters optimum with regard to fuel consumption
was determined. It was found that the propeller pitch
is optimal only in a narrow range of vessel speed but
it is adequate to the actual conditions in which the
Bizon III pusher tug operates.

Despite recent turbulence in the global economy, the
growth of global trade volumes is expected to
continue in the future, leading to increased demands
on the performance of logistics networks. The
political framework for European Union (EU)
Transport Policy Development is presented in the EU
White Paper on Transport 2011 in order to build a
competitive European transport system. One
significant aspect is the promotion of multimodal
transport in order to decrease terrestrial transport
services (road and rail) and to increase services in the
maritime transport sector, especially considering the
relief of road and railway infrastructure. Looking at
the present situation, Short Sea Shipping (SSS) is
already used in many different transport fields all
around the world. However, there still exists a great
potential which currently is not used or not
sufficiently exploited for many different reasons. In
order to identify the potential use of SSS in
multimodal transport, different scenarios in the Baltic
Sea Region and the adjoining hinterland have been
developed pointing out alternative solutions for
routing. These options are analysed in detail and
evaluated from different perspectives (i.e. transport
and handling costs, time consumption and transportrelated emissions). Afterwards, advantages and
disadvantages of each alternative are examined by
taking into account economic and ecological aspects
in making decision.

Over the next few years, the world LNG fleet is set to
expand at an unprecedented rate. With many new
ships and new operators entering the fleet. The LNG
trade depends on safe and reliable ship operation for
its continued commercial success. International
requirements are set by IMO in respect of minimum
training standards for sea-farers, with specific extra
training required to meet the exacting challenge of
carrying cryogenic LNG cargoes. SIGTTO has
voluntarily introduced training standards above and
beyond IMO levels, and has also published a
minimum experience level for the various Senior
Officer ranks on board any LNGC. The paper
examines the challenges facing individual operators and the LNG shipping industry as a whole - from this
sudden upsurge in demand for experienced and
highly-trained sea staff. Set against a background
where recruitment of seagoing personnel is
increasingly difficult, and the fact that it takes around
10 years to train a cadet to take command (either of
an engine room or of the entire ship). The growing
shortage of sea-staff is also affecting experience
levels ashore, which in turn can impact the reliability
of the shipping operation itself. The author draws on
many years experience in training sea-staff LNG to
suggest solutions to this growing problem in the
industry.

The Arctic region is still covered by thick ice and
thus finding a feasible navigating route is essential for
an economical voyage. To find the optimal route, it is
necessary to establish an efficient transit model that
enables us to simulate every possible route in
advance. In this work, an enhanced algorithm to
determine the optimal route in the Arctic region is
introduced. A transit model based on the simulated
sea ice and environmental data numerically modelled
in the Arctic is developed. By integrating the
simulated data into a transit model, further
applications such as route simulation, cost estimation
or hindcast can be easily performed. An interactive
simulation system that determines the optimal Arctic
route using the transit model is developed. The
simulation of optimal routes is carried out and the
validity of the results is discussed.

wave data samples for each route obtained from
global wave climate databases. A comparison of the
results obtained for three wave databases is made for
a grid covering the North Atlantic Ocean. Two
transatlantic routes are considered. The significant
wave height is compared for HIPOCAS, ERA-40 and
COADS data sets, by evaluating the average values
obtained for several periods and performing error
calculations between the different data sets. Similar
patterns were found for several periods and
performing error calculations between the different
sets. Similar patterns were found for HIPOCAS and
ERA-40, the first one showing the higher maxima.
COADS have smaller seasonal amplitude between
maxima. The same procedure is applied to the
average period, only for HIPOCAS and ERA-40 data.
Higher maxima were found for the second and
different contour patterns. Data sets (HIPOCAS e

When it comes to assessing cavitation effects in
propeller design, potential flow codes represent a
quick and fairly reliable tool to determine the main
influence of cavitation on thrust and efficiency
around the design point. This includes to some extent
also pressure pulses of the lowest harmonics.
However, more detailed effects of cavitation, such as
high frequency or broadband noise or erosion, are not
possible to assess with any computational tool today.
Recent results using LES or Euler methods indicate
that these methods are capable of capturing much of
the cavitation dynamics, but high fidelity predictions
of all aspects of cavitation nuisance in reasonable
computational time cannot be expected in the near (or
any) future. Moreover, experiments can only provide
an incomplete picture to assist the designer.
Experience and knowledge are still necessary
components for a successful design. This paper
discusses some possibilities to combine the tools
described above, based on recent years of research at
Chalmers University of Technology on propeller
cavitation and computational tools in propulsor
analysis. The authors remark that this is a review of
work done at Chalmers, and the references reflect this
restriction; a complete review would include a

Currently used scale effect corrections for open
propellers were developed about forty years ago.
Since that time the geometry of propellers has
changed significantly and the accuracy of model
experiments and numerical methods employed for
prediction of propeller open water characteristics has
increased. In order to assess the adequacy of the
classical scale effect corrections for contemporary
propellers the following research plan was created:
four different algorithms for calculation of propeller
scale effect were included in the lifting surface
programs, namely: 1) classical ITTC78 procedure
based on the equivalent blade section at radius 0.75;
2) ITTC78 formulae calculated locally for the
respective blade sections and integrated along the
blade radius; 3) alternative formulae for blade section
drag and lift integrated along the blade radius; 4)
alternative formula for blade section drag only,
integrated along the blade radius. CFD calculations
were performed for the entire range of model and full
scale Reynolds numbers.
Two propellers were
selected: P9 with moderate skewback and CP6 with
high skewback. The complete set of numerical
calculations was performed for all propellers. The
comparison and analysis of the computational results
formed the basis for assessment of the accuracy and
effectiveness of different methods for calculation of
propeller scale effect corrections.

The work presented in this paper is part of the project
BossCEff, which aims to develop propeller hub caps
under consideration of the whole propulsion system,
including propeller, rudder and costa bulb. In order
to find suitable hub cap geometries, the authors
develop an optimisation process that includes the
parametric definition and generation of the geometry,
the mesh generation and the numerical calculation of
the propulsor performance. An optimisation
algorithm is applied to automatically vary the
geometries. This means that all the steps mentioned
also have to work automatically. This paper presents
an overview of the whole process while focussing on
the following: 1) the reduction of the geometry model
information for the numerical setup of the
optimisation process, 2) the geometry definition and
3) the grid generation. Especially the two last aspects
are a challenge if they are to work without manual
intervention.

development. As shown in earlier work (Haase et al.,

ABSTRACTS
2012), medium-speed catamarans will efficiently
operate at Froude numbers of Fr =0:35, but
unfortunately there is a lack of resistance prediction
tools for twin-hull craft in that particular speed range.
Therefore, there is a demand for numerical tools to
correctly determine the resistance of such craft
independent of speed, hull form and scale. Not only
the resistance, rather the hydrodynamic phenomena
occurring at this speed range between the
displacement and planing regime are of interest to
understand the flow to more efficiently design such
craft. A viscous free-surface flow solver has been
chosen to study the fluid-hull interaction for a variety
of different hull forms which are free to heave and
trim. To validate the computational set up the results
of the NPL catamaran series (Bailey, 1976; Molland
et al., 1994) has been chosen. They provide a broad
variation of hull configurations and speeds, where
total resistance, trim, sinkage and wave pattern
resistance has been measured. Experimental results
have to be carefully considered, as the median total
uncertainty may go up to 10% in resistance, 42 % in
sinkage and even 52 % in trim depending on Froude
number and model length, according to Gorski et al.

Reynolds-Average Navier-Stokes equations are stateof-the-art in today’s computational fluid dynamics.
Thereby the accuracy of simulations with RANSE
depends on the numerics and meshes to be used. To
insure a good agreement and stability of the
numerical solutions it is important to investigate how
the different discretisation schemes are influencing
the result. A simple example for the motivation of
this paper is presented; depending on the scheme used
in the simulation the results for the mixing of a fluid
with two velocities look different. Therefore the
effect of these schemes on the numerical results for
ships is investigated. This helps to improve the
trustworthiness of the solutions, especially in cases
where experimental results are not available. A
parameter study is presented where various
discretisation schemes are used for double body
simulations of the well-known KVLCC2 ship model.

Modern shipbuilding and development shows a
strong demand for highly efficient and powerful
propulsion systems. Moreover, tendencies to
maximize the cargo hold leads to a decrease in the
space provided for the propulsion system. On the
downside of this progression are highly tip-loaded
propellers. This can lead to prominent tip vortex
structures and subsequently forwarding to frequent tip
vortex cavitation, hull excitation and rudder erosion.
Within a joint research project of MMG Waren

approach has been investigated claiming the

Propulsion improving devices (PIDs) which focus on
hub near vortex losses are of special interest for
newbuildings as well as for retrofits, because of low
installation costs and reliable energy saving effects.
An important precondition for the design of these
PIDs is the proper numerical consideration of
dominant flow properties. Therefore, the paper deals
with a study of the capability of capturing flow details
like dead water areas behind propeller caps by using
systematically optimised grids. The investigation is
based on three different cap shapes and different grid
refinement criteria. Coming from more globally
optimised grids based on a global criterion the study
also includes local grid optimisation under
consideration of local grid refinement criteria. All
calculations are carried out as open water set-ups
using the grid convergence index method as
recommended by the Journal of Fluids Engineering in
order to obtain grid independent solutions. Thus, the
work has to be seen as groundwork for further
investigations of hub near flow characteristics with
and without propulsion improving devices.

In the scope of this work the capability of the hybrid
turbulence modelling method to predict the unsteady
effects in the wake flow behind a generic inland ship
at shallow water conditions was tested. The analysis
of the results shows, that the vortex structures
predicted using this approach are much more intense
than those predicted by URANS method. The
significant achievement is the reproduction of the
intense boundary layer separation, whereas the
URANS model gave poor resolution. It is shown that
appearance of these phenomena leads to the sharp
change in the velocity field at the propeller location,
and it is apparent that the forces acting on the
propeller will also oscillate more strongly than it is
predicted by URANS. Since the EFD data for the
generic ship are not available, the validation has not
been carried out. Thus, so far it is not possible to
draw conclusions on the prediction accuracy.
However, qualitatively, the effects modelled (such as
the flow separation) are in complete agreement with
the practical observations.

A RANS based prediction allows for phenomena such
as the behaviour of the boundary layer under the
waves and other viscous effects to be modelled. Even
though a prediction based on RANS modelling comes
with much fewer assumptions, the complexity of the
problem means that it is very sensitive to meshing,
selected schemes, boundary conditions etc. Incorrect
predictions of the phase of the hydrodynamic forces
are something that has been highlighted in previous
CFD workshops as one of the weaknesses of using
RANS (Larsson, 2010). For this reason this paper
concerns a fixed hull in waves. Previous studies have
shown that using a fixed hull can give a good insight
into the force distribution on the hull and, using a
body force model for the propeller, predict the selfpropelled performance of a ship with good accuracy
(Turnock et al., 2010). Using a fixed hull also
eliminates any progressive expansion of errors due to
phasing problems which allows for more detailed
studies of phenomena such as boundary layer
disturbances due to the waves and how this affects the
propeller inflow.
To thoroughly validate the
performance of OpenFOAM for predicting the forces
on a fixed hull in waves, a comparative study with
several
wavelengths
was
conducted.
The
experimental data is provided from a study of fixed

The important application of computational fluid
dynamics for marine waterjet performance analysis,
optimal design and propulsion characteristic
prediction is introduced. The solution domain of
waterjet was defined and meshed by hexagonal
structured grids. Turbulence effects were taken into
account by using a shear stress transport turbulent
model. This model was applied to a newly designed
waterjet pump on the basis of grid density
independence was examined. Several qualitative and
quantitative indexes were adopted to evaluate the
diffuser’s rectifying performance and the intake
duct’s
flow-delivering
characteristics.
Some
reasonable suggestions for optimal design were
provided. The flow field of hull and waterjet was
simulated. Area-integration method was employed to
deduce the thrust characteristic, which could make
certain the ship speed and guarantee a successful
outcome.

The objective of this work is to extend a 3-D
boundary element method for modelling the
hydrodynamic response of a surface-piercing
hydrofoil with consideration for the effects of
cavitation and/or ventilation. The problem is
formulated as a mixed boundary value problem for
the perturbation velocity potential. The effect of the
submerged depth based Froude number and
ventilation on the cavity pressure is considered. The
numerical
predictions
are
compared
with
experimental measurements conducted at a free
surface cavitation tunnel. The results show good
comparisons between experimental measurements
and numerical predictions in the base cavitating
regime, when the cavity is closed to the free surface.
When the cavity is open to the free surface, the
pressure in the ventilated cavity, Pc, varies between
the vapour pressure (Pv) and the absolute ambient
pressure (P∞) depending on the angle of attack,
submergence, relative inflow velocity, difference
between P∞ and Pv, and is influenced by hysteresis
effects. Consequently, the lift coefficients vary
significantly. The upper limit of the measured lift
coefficients matched well with numerical predictions
for Pc=Pv (fully attached or base cavitating regime),
and the lower limit matched well with numerical
predictions for Pc=P∞ (fully ventilated regime at very
high Froude number and very low absolute ambient
pressure).

As soon as a vessel does not operate in calm waters
but under the influence of wind, waves and current,
the vessel can drift and the operating conditions
deviate from the so called (single) design point,
normally obtained during the design stage. Under
these circumstances the ship as well as propeller and
manoeuvring devices will operate in off-design
conditions for long term. This paper summarizes the
essential results of investigations done in this respect
at HSVA for the national joint research project OffDesign (2012). By means of propulsion tests and
wake measurements at straight course and under drift
conditions some representative operating points were
identified, defining the off-design conditions of a
RoRo ferry. Propeller and rudder were then
investigated in the cavitation tunnel in these
conditions. Off-design propeller pitch settings were
also investigated. By means of pressure pulse and
cavitation inception test results the propeller
characteristics are compared between straight course
and drift conditions. Rudder force measurements
show the consequences from the rudder point of view.
This study examines the propulsive efficiency of
underwater vehicles which are driven by unsteady
propulsors. The analysis is focused on vehicles
utilizing a novel thruster which expels finite
propulsive jets periodically.
This analysis also
applies to swimming squid and jellyfish (from which
the thruster was inspired), and can also be extended to
any periodic unsteady propulsion. The vehicle
trajectory is solved analytically to calculate the exact
work output/input and it is observed that with
unbounded forcing there is an optimal thruster duty
cycle, λ = 0.31, which maximizes propulsive
efficiency. This optimal duty cycle is very close to
the actual jetting duty cycle observed in steadily
swimming squid.

focused on the interaction between operating and
environmental conditions using a central composite
experiment design with four factors: propeller shaft
speed, declination angle, initial ice concentration, and
distance to the ice edge. It was found that the
propeller shaft speed was the most significant factor
and that increasing propeller rotation speed increased
ice clearing most effectively. To clear ice far
downstream of the propeller, it was found that
directing the propeller wash at the water’s surface
imparts more energy to the ice pieces, causing them
to travel farther.

The development of the new generation of podded ice
capable vessels have benefited enormously from
experimental and full-scale hydrodynamic ice
research. However, despite the broad international
research performed on this topic, only a small part of
the effort has been applied to the modelling of
cavitation during propeller ice interaction. Whilst ice
tanks model the contact forces with good agreement,
the level and influence of cavitation during propeller
ice interaction is often only assumed due to the
inability to scale atmospheric pressure during these
experiments. This paper gives the findings of tests
performed in a cavitation tunnel examining effect of
performance of a podded ice class propulsor
operating in simulated ice conditions. The paper
includes an air milling analysis, which has been
neglected in previous reports on this particular
investigation (e.g. Sampson (2011)). The paper
describes the decomposition of the propulsive
components into open water, blockage, in air milling
and the hydrodynamic component of the milling load
750
in an attempt to understand the contribution of
cavitation in the phenomena. Existing full-scale trials
data of propeller ice interaction are also examined.
The results show the presence of cavitation in full
scale is in keeping with the findings of the research.

The impact of ice on a propeller is a complex process,
which most likely results into a milling or crushing
process, or a combination of both. The highly
dynamic forces during an impact can change rapidly
in amplitude as well as direction. Little information
can be deducted from conventional test setups with
rigid propellers; especially forces on the individual
blades are seldom successfully measured. The paper
outlines the challenges which need to be overcome to
measure these impacts and present results of actual
propeller ice impact measurements. Classic designs
for propeller testing involve rigid propellers with
force measurements located at the base of the
propeller. From this type of setup, two problems
arise. First of all, the blade area and the size of the
impacted ice can be similar. Even in the case of a
high quality measurement, it will be hard to derive
which part of the measured forces contributes to
which blade. Secondly, in practical test situations the
natural frequency of the entire propeller mounted on a
force transducer can be relatively low. Impacts
contain high frequency energy, causing the entire
propeller assembly to vibrate and thereby obscuring a
correct measurement of the impact loads.
A
measurement setup has been designed to overcome
both problems. Rather than all four blades, only a
single blade is mounted on the force transducer. This
particular force transducer is capable of measuring
forces in six degrees of freedom. The other propeller
blades are mounted directly on the shaft. This
ABSTRACTS
measurement setup enabled MARIN to overcome the
first problem, any impact visible in the measured
signals are solely due to forces on the instrumented
‘key’ blade. A series of tests were performed in an
ice basin where propeller ice impacts were measured.
Synchronised high speed video recordings were used
to gather more insight in the complex phenomena that
occur during these short events.

More environmentally friendly solutions are required
for future ships such as STX Finland’s recently
delivered LNG powered cruise ferry. Fuel economy
and green considerations are playing a more
important role.
The ship hull form and its
appendages are the best energy saving possibilities.
Success in hydrodynamic design is following the
whole vessel, its operation life and gives a better
possibility to compete in the harder markets. Today
RANSE based CFD tools have shown their usefulness
in detailed hydrodynamic designs and they are in
routine use in the shipyard design offices. Good
solutions for improved ship designs are podded
propulsion, Dual-End CRP, ECO efficient
conventional propulsion concept and the hybrid
propulsion concept. The different kind of ECO
efficient steps are looked for in twin and triple screw
cruise liners. This includes looking at how to reduce
appendage resistance case by case, what are possible
to reach by ESDs and what practical propulsion
alternatives are available for twin screw cruise liners.

This paper investigates the effect of a duct on
propeller added mass by comparing the propeller and
duct individually with the bodies combined in a
multi-body simulation. This is a preliminary step
towards better understanding of the loads and
responses of a ducted azimuthing thruster in various
extreme load cases and developing a multi-body
simulation model of the thruster with internal drive
train. The numerical analysis is conducted with the
commercial DNV software HydroD, using its
WADAM program. The results show that the
propeller is more affected by the presence of the duct
than the duct is affected by the presence of the
propeller. The presence of the duct on the propeller
increases the uncoupled added mass linear terms by
10% and rotational terms by 33% when compared
with the propeller added mass in isolation. The
influence of propeller on the duct is relatively minor
with the added mass changing less than 3.5% for all
uncoupled terms when compared with the duct added
mass in isolation. Once the bodies are considered to
move independently of each other the effect of each
body on the other is greatly increased with a change
in the coupled added mass terms up to 133%.

This study defined the thrust, drag and torque that act
on a podded propeller unit, and analysed the relation
among these components. By separating the thrust
components of propeller blades and the drag
component of pod housing, application of the general
concept of thrust correction and drag extrapolation
can be made possible. Considering the change in the
drag of pod housing resulted from pod propeller
operation, estimation method of full scale propulsive
performance for the pulling type podded propeller is
suggested. In order to estimate the drag of the pod
housing, a numerical model of drag velocity ratio,
which includes the effects of pod propeller loading
and Reynolds number, is presented and evaluated
through the comparison of model test and numerical
analysis. Especially, the method that can estimate the
full scale propulsive performance of a podded
propulsor at the stage of power estimation of a ship,
which is the early design stage, is proposed.

Different from marine propeller designs, which
752
undergo standard stock and design propeller test
programmes with detailed assessments of the final
design (for the overall propulsive efficiency, the
cavitation performance and the pressure fluctuations,
etc.), final designs of waterjet systems are seldom
tested for their system characteristics, the intake loss
and the cavitation performance. It could be both due
to economic reasons that waterjet system tests are
relatively expensive. It could also be due to technical
reasons, such as, that the operating point of a waterjet
system does not vary too much for different
operational conditions. This means that it also
performs very well for all other operational (offdesign) conditions once a waterjet system is welldesigned for its design condition. However in
practice, mismatching of power absorption and shaft
rotational rate, and cavitation erosion, are
occasionally found after sea trials of waterjet
propelled ships. Remedial action is then required. In
some cases, removing cavitation erosion can be rather
difficult and simple modifications may not solve the
problem. In order to prevent these types of problems
from the early design stage, waterjet system
performance and cavitation tests of the final design
are strongly recommended. Taking a fast river
passenger ferry as an example, test procedures are
discussed in detail in the paper. The scale effects and
the extrapolation method are also addressed. The
results provide a good data set for CFD validation
too.

The importance of considering hub effects in the
design, optimisation and verification of marine
propellers is discussed in the paper. Different design
variants of optimum moderately loaded modern
propellers are obtained by means of fully numerical
lifting line/surface vortex lattice methods, with and
without hub effect. Antisymmetric vortex images are
used to implement the effects of the hub by the vortex
lattice codes. Classical parametric lifting surface
corrections are also used to correct pitch and camber.
Global as well as local (pressure distribution)
hydrodynamic properties of the propellers are
compared as obtained from a fully numerical lifting
surface method, a boundary element method and a
finite volume RANS solver, referred to as the closest
model of the real flow. The comparison permits to
highlight the undesired consequences which a
designer should expect if an inadequate or
inconsistent hub modelling is used in some part of the
propeller design process. Indeed, the best propeller
design, in terms of efficiency, thrust matching and
shock-free condition on its inner section is found
when the hub effect is considered by all the numerical
methods used for design.

The hydrodynamic performance of propellers with
trans-velocity sections are presented in this paper.
The trans-velocity section is developed for not only
having a satisfactory performance, but also having
consistent performance at different inflow speeds.
The development of a design procedure for the transvelocity section and propellers with trans-velocity
sections are first presented. The viscous flow RANS
method is used in the design procedure, and this
design procedure can be also applied to a propeller
with different types of foil sections. Two different
designs are demonstrated in the paper, one is a
propeller with only the trans-velocity section, and the
other one is a propeller with both the trans-velocity
section and a section especially developed for yachts.
The numerical results of the hydrodynamic
performance are compared to the experimental data,
and the performances of these propellers at different
inclined shaft angles are investigated. It is found that
the propeller with hybrid sections has a better
performance than the one with trans-velocity section
only which suffers from a serious thrust loss in
inclined shaft conditions. A pre-swirl stator is also
designed for the purpose of improving the
performance, and it is found to be effective.

In times of increased fuel oil prices the focus within
the ship design process is on efficiency. Especially a
vessel’s propulsion is a key factor in optimising the
fuel oil consumption. Therefore any increase of
efficiency needs to be recognised and evaluated. Ship
owners are increasingly postponing their decision
regarding the propeller supplier after comparative
model tests with two or more different propeller
designs. But as the performance of propulsion is
affected by scale effects these comparisons always
offer room for discussions about the right way to
apply such scaling calculations. Especially propeller
designs with blade shapes that differ from the
conventional type often enforce these discussions.
Therefore the idea of the European project PREFUL
was to investigate the possibilities of improvements
of the scaling calculation in order to consider the
differences between blade shapes more precisely. As
a result the differences between several scaling
procedures are shown, especially in comparison to the
results of the new stripe method, which was
developed within the project.
This paper introduces the new concept of a propeller
with backward tip raked fin. While the author
investigated the hydrodynamic characteristics of a tip
raked propeller, a remarkable effect was found by
bending the blade in the tip region toward the
pressure side, which can moderate the negative
pressure on the suction side. This makes it possible to
reduce a propeller blade area without sacrificing
cavitation performance and improve the efficiency as
a result. A propeller was designed with backward
rake, i.e. bending the tip toward pressure side, for a
container vessel. Propeller open water tests,
cavitation observation and pressure fluctuation
measurement were carried out and the significantly
higher efficiency compared with the conventional
propeller was verified.

The frequency characteristics of unsteady forces
arising from the hydrodynamic interaction between
the rotor and stators for a ducted propeller with preswirl stators is analysed theoretically. It is shown that
754
ABSTRACTS
the axial force and moment fluctuate at frequencies
equal to nZRN on condition that nZR=kZS, where k
and n are both positive integers, ZR and ZS are the
rotor and stator blade numbers respectively, and N is
the shaft frequency of the rotor. The lateral forces and
moments also fluctuate at multiples of the rotor's
blade frequency, but on condition that nZR=kZS±1.
Therefore, the axial and lateral forces do not fluctuate
at the same frequency, and in many cases the lowest
fluctuation frequency of the lateral forces are much
lower than that of the axial force. To evaluate the
amplitudes of unsteady interaction forces, RANS
simulations are carried out for a ducted propeller with
pre-swirl stators. The CFD results of time-averaged
thrust and torque agree fairly well with those
experimentally measured. The unsteady force
fluctuations are quite clearly captured at frequencies
theoretically determined, and are mostly negligible at
other frequencies. The results indicate that, for the
configuration being simulated, the lateral forces
fluctuate at much lower frequencies and higher
amplitudes than the axial force.

blades advance in water as male screws. In this study,
an unconventional ducted propulsor having a shape of
female screw is proposed. It has a duct, a rotating
boss and vanes with screw surfaces installed on the
duct inner surface. Viscous rotational flows caused by
rotating motion of boss are curved by the vanes along
the duct inner surface. According to this inner flow,
suction flows at the front side and accelerated
ABSTRACTS
blowing flows at the rear side can be induced. In
order to increase the rotational flow, protuberances or
roughness should be adopted on the surface of boss.
In the paper, concepts of the new propulsor are
proposed, and results of fundamental experiments
carried out to investigate its basic hydrodynamic
characteristics are reported.

Vessel wave wake characterization using wavelet

RINA Transactions – IJME – part A2, April-June

Robbins, A., Thomas, G., Et al
English
This work focuses on characterising vessel wave
wake (wash) using wavelet analysis when a vessel is
operating in the sub-critical and critical zone. Such
characterisation
complements
other
wash
characteristics: Froude depth number, bow wave
angle, solitons and decay coefficient. The
examination of experimental results indicates that
differences in characteristics with respect to water
depth, Froude depth number, vessel displacement,
hull form and soliton generation can be identified
through wavelet analysis. The results demonstrate
“proof of concept” that wavelet analysis is a powerful
tool for characterising vessel wash and captures the
effects of key operational and vessel changes.

The primary aim of this paper is to increase the
knowledge on flow straightening influence of the
propeller and hull on the effective angle of drift at the
stern of a ship. Preliminary investigations compared
with wind tunnel experiments carried out by Molland
and Turnock [1991, 1995] using a modified
Wageningen B4.40 propeller and Rudder No.2 are
presented. Two separate investigations were
considered. 1. A propeller – rudder combination in
straight line flow (with no applied drift angle) was
conducted to understand the interaction effect. This
study employed a body force propeller model. 2.
Three centre-boards with relatively small thickness
and with three different lengths placed upstream of
the propeller–rudder combination were proposed for
investigation based on the finding in (1) to understand
the effect of an upstream plate on flow straightening.
This study is still under investigation. Real propeller
geometry is employed with the aim of establishing
the use of the arbitrary mesh interface in the current
version of OpenFOAM.

In the last 15 years, influenced by the growing
pleasure craft market and the need for higher comfort
standards, different stabilizing systems have been
studied. Gyro stabilizers and the Zero Speed Fin are
the most used, both of them are able to produce a
stabilizing effect at zero speed and even in the
underway condition, the main differences between
them are that the first one takes more time to be
turned on and off, on the other hand the fins increase
the hull resistance and can be damaged in collision
with floating objects. The working principle of the
gyroscope is well known on the contrary the principle
behind the zero speed stabilizers has not been fully
investigated. In the literature it is possible to find
analytical hydrodynamic models and 2D CFD
simulations and other works in which fins are
compared with antiroll tanks and their use in
anchored conditions is discussed, while CFD
simulations of three dimensional model or model tests
are not present. The objective of this research is to
find out the correct setting to realize an analysis of a
zero speed fin with the commercial CFD code StarCCM+, and later, using this model, to gain a deep
understanding of the fluid dynamical behaviour.

Twin screw ships may experience considerably
asymmetric propeller functioning during manoeuvres.
This phenomenon may result in large power
fluctuations during tight manoeuvres, with increases
of shaft torque up to and over 100% of the steady
values in straight course and considerable unbalances;
this, in its turn, may be potentially dangerous,
especially in case of particularly complex propulsion
plant configurations, such as those with coupled shaft
lines. A joint research project supported by the Italian
Navy has been set up in order to deeply investigate
the phenomenon, by means of large scale model
testing and related numerical simulations. In the
present work, the extensive experimental campaign
results on a free running model of a twin-screw ship
are presented, allowing a deeper insight of the
problem to be obtained. In particular, tests have been
carried out simulating different simplified control
schemes, starting from the most common constant
rate of revolution tests and including different control
strategies (constant torque and power). Usual
standard manoeuvres (turning circle, zigzag and
spiral) have been carried out, providing results for
asymmetric
shaft
functioning
and
ship
manoeuvrability behaviour. Results from the present
analysis allow to obtain the complete model for the

The displacement Deep-V catamaran concept was
developed in Newcastle University, UK through
ABSTRACTS
757
development of the systematic Deep-V catamaran
series. One of the most important Deep-V catamarans
launched to date is Newcastle University's own multipurpose research vessel, The Princess Royal. The
vessel was launched in 2011 and enhanced the DeepV catamaran concept further with the successful
adoption of a novel anti-slamming bulbous bow and
tunnel stern for improved efficiency. It was however
identified that the vessel has substantial amount of
dynamic trim that limited the visibility of the captain.
The dynamic trim also increased the wave-making
resistance thereby preventing the vessel from
attaining its maximum speed in certain sea states.
This paper therefore presents the application of
devices such as Trim Tabs, Interceptors, Transom
Wedges and Integrated Transom Wedges-Tabs to
control the dynamic trim and improvement of fuel
efficiency of the vessel. All of these energy saving
devices were fitted into a model for tests in Newcastle
University's Towing Tank. Model test verification
confirmed that the optimum appendage was the
interceptors, they produced a 5% power saving and
1.2 degree trim reduction at 15 knots, and
investigations of full scale trials will be scheduled
with and without application of device to compare the
improvement of performance.

Höpken, J., El Moctar, O.
English
Both the propulsion devices as well as the
characteristics of the machinery have an influence on
ship manoeuvrability and should be accounted for.
Due to the different timescales between the motion of
the ship and the rotation of the propulsor, a
geometrical modelling of the latter forbids itself. This
modelling would increase the required computational
efforts even more, rendering the entire model as not
feasible. Hence investigating the influence of the
interaction between the propulsion devices and the
758
hull on ship manoeuvring is a challenging task.
Choosing body force models as a compromise
between accuracy and computational effort is a
popular alternative. The aim of this study is to
develop such a body force propulsor, but without a
simple analytic model that distributes the thrust and
torque over the propeller disk. Instead a database is
filled with data gathered from various simulations of
the desired propeller under diverse operational
conditions, prior to the actual manoeuvring
simulation. During the actual manoeuvring
simulations, the volume forces can be calculated from
the pre-computed data and inserted as source terms to
the momentum equation. Although no manoeuvring
simulations can be shown, a validation of the current
body force propulsor implementation is presented
within this paper.

features: any number of overlapping grids can be
used; each grid can be of any type (arbitrary
polyhedra); individual grids can fall partly outside
solution domain; the solution is obtained on all grids
simultaneously (a tight coupling of all equations
through the coefficient matrix is achieved). This
method has substantial advantages over the currently
available approaches in several important application
areas. In this paper the solution method is briefly
described and a number of application examples are
shown to demonstrate the versatility and applicability

An adaptive multi-controller system for a MIMO

The

a surge velocity and yaw angle control system for a 4DOF nonlinear MIMO mathematical model of a
single-screw high-speed container vessel. The paper
presents the complexity of the assumed model to be
analysed and the method of synthesis of the coursekeeping control system. In the proposed coursekeeping control system use is made of a set of (stable)
linear modal controllers that create a multi-controller
structure from which a controller appropriate to given
operation conditions is chosen on the basis of the
measured auxiliary signals. The system synthesis is
carried out by means of system pole placement
method after having linearized the model 4-DOF
motion of the vessel in steady states. The final part of
the paper includes simulation results of system
operation with an adaptive controller of stepwise
varying parameters along with conclusions and final

Controlling the roll motion involves several problems
including incomplete measurements, external
disturbances, and the model uncertainties. In this
paper, the perturbed model for the roll-fin dynamics
ABSTRACTS
is extracted by considering the problems influencing
the fin stabilizer system during ship sailing. The
sliding mode control provides robust performance for
the mentioned factors. Therefore, a sliding mode
controller is designed based on the information about
the upper bound of perturbations and wave excitation
force. Inasmuch as the uncertainty bound is not
usually known, a robust adaptive sliding mode
controller is proposed. Although it has been proven
that the proposed method is robust, the chattering
phenomenon is accounted as a drawback of the
sliding mode control. In order to overcome the
chattering phenomenon, a second-order sliding mode
is replaced by the first-order one to create an adaptive
second-order sliding mode control. The simulation
results show that the control strategy is effective to
decrease the roll motion and robust to overcome the
uncertainties and random waves.

applied to calculate the source of the external wave

known as the “Three Sisters”. The main purpose
behind the experiment is to check the behaviour of
the ship in extreme seas states. These experiments
revealed little but the key influence of green water
shipping on the ship responses especially on the
sagging moment and is used as a guideline to modify
the time domain code in a heuristic manner to
incorporate the green water effect. The updated

Based on the potential theory, a code using the panel
method has been devised to estimate the
hydrodynamic interaction forces acting on ships in
motion in confined waters, near a bank, in a canal or
over a dredged channel. The approach presumes
distributing a source layer on the ship’s wetted
surface and also on a sufficiently large patch moving
over the water boundaries of concern. The source
distribution is discretized using constant-density flat
quadrilateral panels. Appropriate arrangement and
panelling of the moving patch constitute an important
part of the algorithm. The algorithm was tested by
comparing numerical results and analytical results for
added masses of isolated ellipsoids in unbounded
water, and by comparing the numerical and analytical
results for pressure distribution, surge and sway

For a ship navigating along a bank in restricted
waters, it is usually accompanied by obvious bank
effect which may cause ship-bank collision. In order
to avoid collision, it is necessary to provide control
force and moment by using control devices such as a
rudder. In this paper, CFD method is applied to
numerically simulate the viscous flow around a ship
appended with a rudder sailing along a bank.
Systematic simulations are carried out for the hullrudder system with different rudder angles at different
ship-bank distances and water depths. The flow field
features and the hydrodynamic forces of the hullrudder system are obtained and analysed. This study
is of significance for revealing the physical
mechanism behind the bank effect and providing
guidance for ship steering and control in restricted
waters.

Extreme manoeuvres for America’s Cup sailing

Mansbridge, J.R., Binns, J.R.

This paper explores the manoeuvring aspects of the
34th International Americas Cup catamarans as the
current rule draft allows using the Futureship GmbH
developed program FS_Equilibrium. With the results
of this analysis the implications of implementing
other manoeuvring solutions including varying the
762
size of the rudder and the implementation of a pure
drag rudder are investigated. The effectiveness of
varying the rudder size was tested by specifying
different lateral areas with a consistent chord length
and profile shape. It was concluded that increasing
the rudder size allowed the vessel to turn sharper but
reduced overall speed due to the increased drag. In
addition it was shown that the optimum rudder size
for the manoeuvre specified, had a lateral area of 1
m2 and a wetted surface area of 2m2. This rudder size
was then tested against a new proposed design, here
termed the pure drag rudder in order to determine any
possible performance gains. It was concluded that the
addition of the pure drag rudder caused the vessel to
turn with a much smaller radius at the expense of
forward speed. It was determined however that this
loss in forward speed was outweighed by the smaller
radius of the turn and the potential tactical gains to be

Suspension boat dynamics.
RINA Transaction - IJSCT, v 155 part B1, JanuaryJune 2013 http://www.rina.org.uk/ijsct.html
Grenestedt, J.L.
English
Small boats operating at high speeds often see very
high vertical accelerations, which impose large loads
on the boats as well as on their occupants. A boat
concept with suspension was developed to reduce
vertical accelerations. It consists of a centre-hull that
is generally not in contact with the water and one or
more sponsons connected to suspension links, springs
and shock absorbers. Numerical simulations were
performed on a simplified 4 degree-of-freedom model
operating in seas generated from wave buoy data. A
suspension boat with the general size and mass of an
NSWRIB 11 meter boat was analysed and optimised.
The analyses indicate that the suspension boat could
operate at 60 knots in sea state 3 without seeing
vertical accelerations above 1.5 G. The same boat but
with rigidly mounted running surfaces would see an
order of magnitude higher vertical accelerations.

The first decision to make in a structural load
assessment is what approach should be applied, a
linear approach or a non-linear one. The correct
decision comes from understanding of the technology
used in the linear and non-linear approaches and also
comes from the understanding of the problem to be
analysed. From engineering practice, it has been
found that many non-linear effects can be taken into
account in a linear model with appropriate approach.
A study of hydrodynamic structural load on a stinger
of a pipe-laying vessel is presented in this paper. The
results of a non-linear analysis are compared to those
of linear models with different approaches, and how
the nonlinear effect can be involved in a linear model
is discussed. The recommendations on how to
estimate the non-linear effects in a linear structural
load model is discussed.

This paper discusses the viscous damping effect on
the first order motion response of a Truss Spar
platform by calculating the damping matrix. The
damping matrix is built for numerical calculating with
the purpose of evaluating the energy loss in system
moving. As a rigid body in the sea, the main damping
is viscous damping between platform and flowing
water, and that is the velocity force. Using the
formula of velocity force, different parts of a Truss
Spar, including hard tank, soft tank and heave plates,
are considered to calculate the viscous damping,
respectively. In this paper, two different numerical
results, with damping matrix and without damping
ABSTRACTS
matrix, are given respectively. Then the nature
periods of a Truss Spar for surge, heave and pitch are
obtained by comparing the time history lines. Another
study is to analyses the viscous damping effect with
constant wind and constant current action on the
Truss Spar. Numerical results show that the platform
would move to equilibrium position quickly by
increasing the value of viscous damping, when the
moving process is neglected.

The concept of the natural frequency is useful for
understanding the characters of oscillating systems.
However, when a circular cylinder floating
horizontally on the water surface is heaving, due to
the hydrodynamic forces, the system is not governed
by the equation like that of the harmonic one. In this
paper, in order to shed some light on the more correct
use of the concept of the natural frequency, a problem
of the heaving circular cylinder is analysed in the
frequency domain. Previously, it was thought that the
theory of Ursell (1949) could not be used to get the
added mass and wave-making damping for short
waves; however, they were obtained by applying an
accurate collocation method to the theory in this
study. Using the so developed numerical method, the
added mass and wave-making damping of the circular
cylinder was found for the entire range of the
frequency. Then, the Modulus of Complex Frequency
Response (MCFR) was used to locate the frequency
corresponding to the local maximum of MCFR and it
was defined as the natural frequency. Comparing the
results with the previous investigation, it was found
that the pressure distribution on the cylinder gets
close asymptotically to that of a cylinder in infinite
fluid OR close to that of the cylinder, that the
approximation of the natural frequency by Lee (2008)
is different from the new value only by 0.64%, and

The sloshing effect on the roll motion and 2-DoF

This study investigates the sloshing effect on the
motions of a two-dimensional rectangular cylinder
experimentally and numerically. The modes of
motion under consideration are sway and roll, and
also experimental cases are divided by two
categories; 1-DoF roll motion and 2-DoF motion
(coupling sway and roll). It is found that the sway
response is considerably affected by the motion of the
fluid, particularly near the sloshing natural frequency,
while the roll response changes comparatively small.
The dominant mode of motion is analysed for 2-DoF
experiments as well. The measured data for 1-DoF
motions is compared with numerical results obtained
by the Multi-modal approach. The numerical schemes
vary in detail with the number of dominant sloshing
modes; i.e. there is a single dominant mode for the
Single-dominant method, while the Model 2 method
assumes that the first two modes are superior. For the
roll motion, numerical results obtained by the two
different methods are relatively in good agreement
with the experiments, and these two results are
similar in most wave frequency range. However, the
discrepancies are apparent where the fluid motion is
not governed by a single mode. But both of numerical
methods over-predict the motion at the vicinity of the
sloshing natural frequency. In order to correct
the discrepancy, the modal damping needs to be
765
investigated more precisely. Furthermore, another
multi-modal approach, such as the Boussinesq-type
method, seems to be required in the region of the
intermediate liquid.

The study of underwater explosions (UNDEX) on
ship/submarines became of interest during World
War II when torpedo explosions near a ship created
more damage than a direct hit. Following the war,
many full scale ship shock trials were conducted by
various countries providing the empirical data that is
widely employed. The biggest threat to any marine
platform is due to underwater weapons and hence
understanding the phenomenon is essential. The
sequence of events involved in an UNDEX starting
from the detonation, shock wave, bubble pulses and
cavitation have been introduced and the dynamics of
the process including governing laws have been
outlined in the paper. The associated aspects of
loading and method of analysing the fluid structure
interaction have also been highlighted. The
development of such numerical methods to analyse
the explosion and its effect on the fluid-structure can
lead to design of safer ships and submarines.
Moreover, the numerical simulation will eliminate the
need for conducting expensive shock tests and trials.

The object of this research is the investigation on the
role of hydroelasticity during a wave impact against
an elastic plate inserted in a rigid wall of a sloshing
tank: the flip-through impact had been considered.
Through Froude scaling, the geometrical dimensions
and the mechanical characteristics of a panel of Mark
III type tank have been defined. Strain gauges and
pressure transducers have been used to measure the
deformations of the elastic wall and the
hydrodynamic pressure. To evaluate the effect of the
hydroelasticity, the same phenomenon has been
reproduced both on rigid and elastic wall. Although
the overall kinematical evolution of the impact is
quite similar, strong differences have been observed
from the dynamical point of view between elastic and
rigid case. A free-oscillation behaviour after the
maximum peaks, characterizes the evolution of the
stress along the wall. The hydroelastic interaction
deeply modifies the pressure field with respect the
fully rigid case, by originating an oscillatory
component and increasing the maximum pressure
peak. This behaviour should imply that a quasi-static
model can strongly underestimate the real load.

force acting on a plate subject to oscillatory flow for
KC numbers ranging from 1.4 to 105. For this
purpose 3D CFD simulations were conducted on a Ushaped water tunnel configuration believed to be the
same as used by Sarpkaya and O’Keefe (1996) in
their experimental investigation. With each flow
oscillation vortices are shed from the tip of wallmounted bilge keel plates installed at the middle of
the water tunnel. The strength of such vortices is
characterized by the KC number as first described by
Keulegan and Carpenter (1958). The KC number is
calculated as KC = UmT/h where Um is the
maximum velocity in the oscillating flow, T is the
cycle period and h is the height of the plate. The
normal force on the plate can be characterized by
drag and inertia components associated with
coefficients Cd and Cm respectively, the like of
which were reported by Sarpkaya and O’Keefe
(1996) for their configuration. Such coefficients are
used by Van ’t Veer et al. (2012) in a methodology to
calculate the oscillatory loads on bilge keels of ships
operating at zero forward speed in irregular sea states.
In Van ’t Veer et al. (2012) 2D CFD simulations were
used, similar to the approach of Kinnas et al. (1992).

Flow around streamlined bodies at high Reynolds
number is an important class of model problems for
ship hydrodynamics in general, and submarine
hydrodynamics in particular. With an axisymmetric
body on a straight course, as studied here, the flow is
dominated by; (i) the development of the turbulent
boundary layer, affected by the pressure gradients
caused by the shape of the body; (ii) the low-velocity
region over the stern, with possible unsteady flow
separation and; (iii) the wake flow. In this study, the
authors use RANS-models implemented in the opensource CFD software OpenFOAM to investigate the
flow around a baseline submarine hull. It is referred
to as the Joubert model after the author of the design
report. In a recent paper by Anderson et al (2012),
extensive data, obtained both with measurements and
large-eddy simulation (LES), was published, both for
baseline hull and the appended configuration with sail
and rudders. In the present study a systematic
simulation campaign is carried out in order to

The effect of nonlinear wave run-up along columns in
steep waves is a prominent top and also an important
aspect in air-gap prediction of semisubmersibles. In
768
this paper, a 3D numerical wave tank is created based
on N-S equations and continuity equations, in which a
regular wave is generated based on a flap wavemaker
similar to a physical deepwater offshore basin. Model
tests were conducted to confirm this numerical
method and obtain the optimal mesh strategy. Wave
diffraction and run-up effects are simulated in this
numerical wave tank. Hexahedral meshes are created
in all fluid regions based on multi-block coupling
technology in order to increase iteration speed and
accuracy of the solution, also capture free surface
much smoothly. Results indicate that distributions of
water surface around semi-submersible can be
obtained in detail through this method. Moreover, the
areas of strong nonlinear wave around a platform can
also be predicted, which is also a key basis to
determine installation locations before model tests.
The wave surface is similar with model tests which
indicates further that this numerical method is
feasible primarily in run-up simulation. In addition,
the process of wave diffraction and run-up along
columns is also simulated from physical
phenomenon, which will provide an important
reference for further research on the nonlinear
interaction between waves and offshore structures.

The behaviour of the water column in the moonpool
and the interaction with the structure can potentially
be predicted with model tests and numerical analysis.
The experimental data publically available typically
focuses on the behaviour of the moonpool for a
certain sea state/sailing condition or focuses on
slamming forces for a specific type of structure
during water entry. Also in CFD the simulation of the
behaviour of the moonpool is generally split from the
simulation of the interaction between water column
and structure. In this work, a hybrid approach is
used. The motion of the water column in the
ABSTRACTS
moonpool is derived from model test data while the
interaction of water-structure is reproduced in CFD
using the water level fluctuation from model tests as
input. Analyses is performed with STAR-CCM+.
CFD plays an important role in the evaluation of the
fluid structure interaction. CFD is considered as a
cost-effective tool complementary to model tests to
obtain hydrodynamic coefficients. For this reason, it
is important not only to understand the possibilities,
but also the limitations of CFD. In order to assess
how CFD can predict slamming forces a validation
study is also presented; it refers to a water entry of a

which is considered representative for this
application. After the validation the results for a

the 3D hydroelasticity method. The structural
vibration response characteristics of a SWATH ship
are analysed. The natural frequency characteristics of
the hull and the local structural vibration response
excited by a diesel generator are predicted when in 0
kn and in navigation. The predicted results are
compared with the test results of the ship, and
illustrate that the analysis method is effective for the
prediction of overall vibration and forced vibration of
the hull excited by mechanical force. The near and far
field underwater noise radiations of the SWATH ship
are predicted by the hydroelasticity method also. The
predictions are compared with the measured results,
showing that the present method is also rational for

The deformation adversely affects the turbine
performance in many cases. For better designs of tidal

blade deformation are necessary. First, performance
prediction of tidal stream turbines were carried out
without considering the deformation and in
conventional inflow condition, and then its results
were compared with existing experimental data. The
computed power coefficients for various tip speed
ratios were predicted quite closely to the experimental
data. Then numerical analyses to consider fluidstructure interaction (FSI) for deformation of the
turbine blade were carried out by using partitioned

understanding of their coupled fluid and structural
behaviour. Due to economic and time limitations it is
preferable to use computer simulation based results
with satisfactory validation. Validation study for a
twisted bend-twist coupled hydrofoil using
experiments has been carried out using finite element

to analyse the wave radiation by multiple or a group
of cylinders in the time domain. The nonlinear free
surface and body surface boundary conditions are
satisfied based on the perturbation method up to the

potential problems at each time step are solved
through a Finite Element Method (FEM). The matrix
equation of the FEM is solved through iteration and
the initial solution is obtained from the result at the

required is generated based on a two-dimensional (2D) hybrid mesh on a horizontal plane and its
extension in the vertical direction. The hybrid mesh is
generated by combining an unstructured grid away

The tip vortex cavitation and its relevant noise has
been the subject of extensive researches up to now. In
most cases of experimental approaches, the accurate
and objective decision of cavitation inception is
primary, which is the main topic of this paper.
Although the conventional power spectrum is
normally adopted as a signal processing tool for the
analysis of cavitation noise, a faithful exploration
cannot be made especially for the cavitation
inception. Alternatively, the periodic occurrence of
bursting noise induced from tip vortex cavitation
gives a diagnostic proof that the repeating frequency
of the bursting contents can be exploited as an
indication of the inception. This study, hence,
employed the Short-Time Fourier Transform (STFT)
analysis and the Detection of Envelope Modulation
On Noise (DEMON) spectrum analysis, both which
are appropriate for finding such a repeating
frequency. Through the acoustical measurement in a
water tunnel, the two signal processing techniques
show a satisfactory result in detecting the inception of
tip vortex cavitation.

The objective of this paper is to investigate the

(least-squares finite element method) for SWE
(shallow-water equations), and develop a better
conditioned shallow-water model to simulate current
structure interactions. Various formulations of
LSFEM for two-dimensional vertically-averaged nonviscous shallow-water equations can be constructed,
depending on the choice of norm, variables,
interpolations, and possible treatment of boundary
conditions. The condition number of the resulting
system of equations is systematically examined and
compared. It is found that condition number of the
resulting system of equations depends on the choice
of variables, interpolations, and size of element (h).
Order reduction (UW) formulations, with introducing
auxiliary variables, with low-order interpolation is
better conditioned and more efficient than direct (U)
formulation with high-order interpolation. However,
to resolve large gradients and fine structures of flow
filed, high-order methods are generally preferred. The
developed shallow-water model is used to simulate
flow past an elliptic hump and flow past a cylinder.
Computed results are compared with other numerical
solutions.

the physics involved, both in terms of the
hydrodynamics and structural mechanics. Out of all
those complexities, the proper selection of the design
sloshing load which is applied to the structural model
of the LNG cargo containment system is one of the
most challenging due to its inherent randomness as
well as the statistical analysis which is tightly linked
to the design sloshing load selection. In this study, the
response based strength assessment procedure of an
LNG cargo containment system has been developed
and proposed as an alternative design methodology.
Sloshing pressure time history, measured from the
model test, is decomposed into wavelet basis function
targeting the minimization of the number of the basis
function together with the maximization of the
numerical efficiency. Then the response of the
structure is obtained using the finite element method
under each wavelet basis function of different scale.
Finally, the response of the structure under entire
sloshing impact time history is rapidly calculated by
synthesizing the structural response under wavelet
basis function. Through this analysis, more realistic
response of the system under sloshing impact
pressure can be obtained without missing the details
of pressure time history such as rising pattern,
oscillation due to air entrapment and decay pattern
and so on. The strength assessment of the cargo
containment system is then performed based on the
statistical analysis of the stress peaks selected out of
the obtained stress time history.

Optimisation of the sectional shapes of wings in

by using computational fluid dynamics (CFD) and
multi-objective optimisation technology. The primary
factors of the aerodynamic characteristics of the
wings in ground effect are the lift force, the static
ABSTRACTS
height stability, and the lift-to-drag ratio. The strong
trade-off among aerodynamic characteristics makes it
difficult to simultaneously satisfy the design
requirements of high aerodynamic performance and
high stability. In this study, three characteristics – the
lift coefficient, the aerodynamic centre of height, and
the lift-to-drag ratio – are chosen as the objective
functions. The aerodynamic centre of height is
selected, rather than static height stability, because it
is more suitable for single airofoils optimisation and
can be directly extended to a WIG vehicle. Also, 18
coordinates in the sectional airofoils are adopted as
design variables. In multi-objective optimisation, the
optimal solutions are not unique, but are a set of nondominated and potential optima, called Pareto optima
or Pareto sets. The Pareto optima (113 individuals)
include various airofoils shapes such as a flat lower
surface and a convex lower surface next to the trailing
edge, which show high lift and high stability,
respectively.

The performance of a rigid wing sail was studied by
wind tunnel experiments. The lift and drag forces
were measured for a range of angles of attack and
flap deflections in order to get information about the
sails performance envelope. The results obtained
show that the rigid wing sail behaves like a traditional
cloth sail when sailing against the wind, but has
limitations on its performance when sailing in favour
of the wind. These limitations are related to the rigid
sail’s design as an airplane wing which does not
account for operation in the low lift to drag ratio
regime, contrary to the design of traditional sail

Most sailboats use flexible sails to generate the

America’s Cup sailboat competition, rigid sails were
specified. These sails resemble an airplane’s wing
and traditional wing-design tools (computational and
experimental) were used to study the performance of
the multi-element sail system. The shape of the
proposed sail is based on two, tandem, symmetric
airofoils, resulting in a geometry, unlike any
traditional two-element airofoil. Because racing
regulations limit the sail shape, only the twodimensional airofoil geometry was open for a
redesign. Therefore, the first objective of this study
was to identify the possible variables affecting the
aerodynamic performance of such sails (within the
framework of racing regulations). At the same time, a
secondary objective was to evaluate the effectiveness

Turbulent flows in maritime applications usually
contain a wide range of length and time scales,
especially for high Reynolds numbers. Therefore, it is
not feasible to solve such flows with direct numerical
simulation. To reduce CPU-times, a model is
proposed. Verstappen et al. proposed an LES model
based on regularization. The regularization model
filters the convective terms in the Navier-Stokes
equations without adding any artificial dissipation.
The spatial discretization preserves the energy too.
This is quite important, since artificial dissipation can
interfere with the subtle interplay between inertia and
dissipation of the flow. A novel aspect of this
research will be to implement the regularization
model on unstructured grids. On these grids, the
authors hope to get similar behaviour as for structured
grids. The symmetry preserving discretization and
regularization model are being implemented in
MARIN's in-house CFD solver ReFRESCO.
Furthermore, the authors expect that the new
discretization and modelling techniques allow LES
computations on a coarser mesh/larger time step
while maintaining the same accuracy, resulting in a
reduced computation time. In ReFRESCO, the
incompressible
Navier-Stokes
equations
are
discretized with a finite volume approach. The

performance assessment of ship hulls under sudden
damage accounting for different operational
conditions is presented. Grounding and collision
accidents are considered as sudden damage scenarios.
The combined effects of sudden damage and
progressive deterioration due to corrosion are
investigated. The performance of ship hull is
quantified in terms of ship reliability and robustness.
The longitudinal bending moment failure is
considered as the limit state. The longitudinal
bending moment capacities of the intact and damaged
ship hulls are assessed using an optimisation-based
version of incremental curvature method. The waveinduced loads for different ship speeds, headings and
sea states are identified based on hydrodynamic
analysis and the ship performance under different
operational conditions is investigated. The approach
is illustrated on an oil tanker. Under different
operational conditions the reliability index associated
with the intact and damaged ship hull and the
777
robustness index associated with damage scenarios
are presented in polar plots. In addition, aging effects
on ship reliability are investigated.

The fatigue life of a steel catenary riser (SCR) at the
touch-down point (TDP) is substantially affected by
its interaction with the seabed. In order to broaden the
understanding of seabed effects on TDP's fatigue
performance and provide more accurate fatigue life
prediction in the SCRs design, the effects of the
seabed characteristics on fatigue damage of the SCRs
at the TDP have been studied in this paper. In this
study, a new element at touch-down zone (TDZ) is
created to simulate the riser-soil interaction based on
the proposed linear hysteretic riser-soil interaction
model. A conventional twin-pontoon semisubmersible with a particular riser geometry in the
South China Sea is adopted to evaluate how the
fatigue damage was affected by the seabed
characteristics. The results based on this study
indicate that: 1) Larger mudline shear strength and
shear strength gradient corresponding to stiffer
seabed lead to shorter fatigue life. 2) The seabed
suction effect could not be neglected in the SCRs
design, since its effect on the TDP's fatigue damage is
obvious and the greater suction force causes more
fatigue damage. 3) The deeper the trench, the less
TDP's fatigue damage will be. Therefore the
development of trench is in favour of longer fatigue
life of the riser.

ice impact were measured from several strain gauges
installed at the bow part were gathered. It is known
that these data with structural response characteristics

Ship structural stress real-time monitoring system
(SSSRMS) achieves real-time monitoring and
evaluation of the ship structure strength by implanting
strain sensors on the hull structure. The method of the
selection of stress monitoring points in SSSRMS was
studied. The response functions of structure stress
under external loads were obtained through the
method of the whole ship structural finite element
analysis. The monitoring points were selected in two
methods which are finding the monitoring points

Uncertainties of wave loading are a large part of the

formulas are built for wave spectrum, sea wave
height, wave loading transfer function, cross-zero
period, sea state occurrence possibility and wave
direction, to investigate the uncertainties of wave
loading during calculation of fatigue loading. The
wave loading model trial is taken to assess the
uncertainty of wave loading transfer function. The
correcting formulas of significant wave height and
mean cross-zero period in the Northwest Pacific are
regressed statistically after specially calculating the
sea states in Northwest Pacific and South China Sea,
and the influence factors of different season sea states
and principle of wave direction distribution to wave

investigated. Finally, the fatigue reliability index of
typical structures for semi-submersibles is researched
on the basis of uncertainties of wave loading and the

the effect of slamming and flooding of watertight
adjacent compartments.
The studies were
780
accomplished using the finite element method applied
to the vessel model, giving special attention to the
bow and stern of the craft when submitted to
slamming effects and jet thrust loads, respectively.
The modes and frequencies of vibration were
determined to check for structural resonance
problems due to slamming induced loads, considering
the sea conditions where the craft operates. The
forced frequency response of a specific region on the
bow was also determined when subjected to
slamming loads applied in a frequency range from 25
to 80 Hz. The results revealed that the maximum
stress induced in the structure was lower than the
yield strength of the materials used in the production
of the craft, the aluminium alloys 5083-H111 e6082T6.
Hypothetical flooding of watertight

Stress triaxiality is recognized as one of the most
important factors for predicting the failure strain of
ductile metals. This study deals with the effect of the
average stress triaxiality on the failure strain of a
typical low-temperature high-strength marine
structural steel, EH36. Tensile tests were carried out
on flat specimens with different notches, from
relatively smooth to very sharp levels. Numerical
simulations of each specimen were performed by
using ABAQUS. The failure initiation points in
ABSTRACTS
numerical simulations were identified from a
comparison of the engineering stress vs. strain curves
obtained from experiments with simulated ones. The
failure strain curves for various dimensionless critical
energy levels were established in the average stress
triaxiality domain and compared with the identified
failure strain points. It was observed that most of the
failure initiation points were approximated with a
100% dimensionless critical energy curve. It was
concluded that the failure strains were well expressed
as a function of the average stress triaxiality.

The application of stud-arc welding to cyclic loaded
primary ship structures was investigated. Thereby
M8- and M12 studs were welded on the bulb of
Holland profiles using the drawn stud-arc welding
with ceramic ferrules. Several fatigue tests were
performed, varying the stiffener size, the stud
diameter, its position on the bulb, the welding
position, weld parameters, residual stress state and the
static load in the stud. The obtained fatigue strength is
above FAT 80 and only slightly affected by these
factors. Hence, the investigated stud-arc welding can
be applied at Holland profiles in primary ship
structures, provided the quality criteria are met. In
order to transfer the results to other geometries and
load situations, the applicability of the effective notch
stress approach was investigated. The corresponding
finite element calculations using idealized weld
shapes and a reference weld toe radius of 1 mm
showed an insignificant influence of the weld
geometry on the notch stress. The determined notch
stresses for each test series was above the design S-N

A new trigonometric shear deformation theory for
sandwich and composite plates is developed. The
proposed displacement field, which is “m” parameter
dependent, is assessed by performing several
computations of the plate governing equations. The
theory accounts for adequate distribution of the
transverse shear strains through the plate thickness
and tangential stress-free boundary conditions on the
plate boundary surface, thus a shear correction factor
is not required. Plate governing equations and
boundary conditions are derived by employing the
principle of virtual work. The exact solutions for
bending analysis are presented for sinusoidally and
uniformly distributed loads. The accuracy of the

A layerwise finite element formulation of a newly
developed layerwise theory for the flexure of thick
multi-layered panels is presented. The displacement
model accounts for nonlinear and constant variation
of in-plane and transverse displacement through the
panel thickness. Reissner-Mindlin approach is used
to model the faces of the sandwich structure. The
displacement field for the core is modelled as
quadratic function of the thickness coordinate. The

three dimensional problem is reduced to the twodimensional one by through-thickness integration of
the strain energy. The discrete element chosen is a
four-nodded quadrilateral with nine-degrees-offreedom per node (when shear continuity is imposed).
An example problem is provided for a well-known
sandwich composite plate. The accuracy of the code
is ascertained by comparing it with various available
results in the literature.

A finite element (FE) analysis is conducted of 120
configurations of stiffened panels with different
boundary conditions to analyse the influences of the
stiffener’s geometry and boundary conditions on the
ultimate strength of long stiffened panels under
compression. The long stiffened panels with four
types of stiffeners are made of mild or high tensile
steel and have bar, ‘L’ and ‘U’ stiffeners. From the
results of the FE analyses, it is concluded that two of
the four models studied can produce adequate
boundary conditions at the loaded edges
longitudinally. The stiffened panels with different
combinations of mechanical properties and geometric
configurations are considered. The initial geometric
imperfections affect the collapse behaviour of
stiffened panels and are analysed in FE analyses.

A sudden increase in bulk carrier losses in the early
1980s caused considerable alarm in the shipping
industry. This paper presents corrosion rate models
for the structural components of high tensile steel
(HTS) and demonstrates corrosion as affected by
various factors determining the microclimate in the
holds. For specimens buried in coal from Australia
and Indonesia, the difference in mass loss was similar
and almost negligible. Average corrosion rates for all
specimens under various stress levels vary
nonlinearly over time, especially during the first 48 h.
Regarding the corrosion rates of specimens; generally
the corrosion rates of specimens under the same stress
in Australian coal were slightly higher than those of
specimens in Indonesian coal between 48 and 240 h.
The corrosion levels for most HTS specimens did not
correspond to the ranking of stress levels they
suffered throughout the experiment. The mass loss for
specimens in Indonesian and Australia coal under
stress levels other than 95% was similar at 2 h and
96 h. The pattern of corrosion that has been observed
for steel in sand and soil also occur for fine-particle
coal in this investigation. The corrosion rates of HTS
covered by both coals were highly dependent on the
quantity of water contents.

Seawater is generally considered to be the most
corrosive of the natural environments which threatens
all the steel structures in their life time. The effect of
environmental marine factors is extremely important
in its corrosive behaviour. In this article, the influence
of different marine parameters including pH,
temperature, salinity and velocity is evaluated on the
corrosion rate of SS 304 samples under turbulent
condition. Since in actual marine environment, the
entire parameters act simultaneously and as there is
the possibility of differences between individual and
synergistic influences of effecting factors, the
influence of each considered parameter on the rate of
corrosion has been studied under the combined effect
of other factors. Finally, the results are presented via
the graphs of dual factor effects which illustrate twoby-two influences of environmental parameters on
corrosion rate variation. This research presents the
difference between the qualitative and quantitative
effects of a parameter under different ranges of
considered parameter and also under the simultaneous
effect of other combined acting factors, which
emphasizes the importance of synergistic effects. In

The new IMO Performance Standard for Protective
Coatings (PSPC), mandatory since July 2008 for new
ships, is described. An evaluation is made of the
PSPC troublesome impact in coast and time needed
for ballast tank and double-skin spaces coating
application in new ships, if the new standard is
applied strictly, using traditional coating technologies
and application methods. But the menaces of strict
application of the new PSPC can be avoided, thanks
to the PSPC openness to innovation. This paper also
reviews the IMO PSPC regulation to highlight the
parts clearly encouraging innovation and offering
opportunities for innovative products and methods to
be used in order to save time and coats. A living
proof of this possibility is presented, describing a
solvent-free humidity tolerant epoxy coating system
able to be applied over water jetting as surface
preparation method in the block stage and over a
zinc-free organic shop primer. Current PSPC type
approvals and testing performance data of the
innovative coating system are presented, together
with hard-facts from application in real-life PSPC
projects now running.
A conclusion is made
suggesting that IMO new standard can indeed be the
tool for more effective corrosion protection without
forgetting the need for shipyard efficiency.

Some 17 4PH propeller shafts showed severe
localised corrosion after a long period of time in
Ancona harbour. The shaft is concentrically mounted
in an AISI 304 stern tube through two rubber
bearings. Both 17 4PH and AISI 304 stainless steels
were characterised by anodic polarisation in natural
sea water, in order to obtain the necessary corrosion
parameters for designing a suitable cathodic
protection of the propeller system. The cathodic
protection effectiveness was tested on a portion
(about 1 m long) of this system. Two cathodic
protection methods were tested: an impressed current
cathodic protection at −0·3 V(SCE) and a galvanic
cathodic protection. The tests were performed both in
stagnant and in moving sea water and the results
showed that these cathodic protection solutions were
able to protect the propeller system; in particular
some guidelines are suggested for both old and new
ships.

limitations, inadequate or non-existent removal routes
and other accessibility problems may result in
expensive equipment overhaul and replacement
procedures, invasive removal methods, longer
maintenance availabilities and increased maintenance
costs. This highlights the need for a better
understanding of Life Cycle Cost (LCC) implications
early in the ship design process and development of
better tools to aid early stage design decision making.
This paper explores a methodology that combines
existing and proven techniques to rapidly generate
and objectively compare valid ship compartment
configurations in consideration of the effects on LCC.
The proposed methodology utilises life cycle costing
techniques and a genetic algorithm within a Multi

objective of this paper is to demonstrate the
methodology rather than provide a specific or defined

BMT Defence Services developed the “Venator”
concept in 2007 to investigate and illustrate the
design of a platform which would deliver capability
through the use of off-board systems and would allow
a common class of platforms to individually embark
different mission equipment’s. Since the original
concept BMT has continued to evolve the concept
and the underlying understanding of capability. This
paper presents aspects of this further work, including
the use of capability mapping and characterisation
methods to better understand the required operational
performance and a balanced affordable design. It
explores the inter-relationship between capability
characteristics and the platform’s design parameters.
It also examines design orientated issues such as the
integration of off-board vehicles into future minor
warships, appropriate levels of survivability, and
pragmatic levels of modularity that can be achieved
in future designs. The paper uses the most recent
evolution of the Venator design to explore these
themes, illustrating the aspirations for a future “Patrol
Frigate” and the constraints faced by the naval
architect in delivering practical and cost effective
solutions. A particular theme of the design
development is the exploration of “flexibility” and
what can be achieved within a design and how such
flexibility can be managed through the capability
mapping and characterisation methods.

The purpose of this paper is to introduce an
innovative methodology in shipping investment
evaluation based on simulation of a project cash flow.
It concerns a complementary approach to current
practices and its aim is to provide more information
mainly to ship-owners that consider the feasibility of
deploying Ro-Ro Passenger ferries. The paper
examines a typical semi-conventional RoPax ferry
operating in the Aegean Sea. It addresses important
economic, operational and procedural issues
concerning risk evaluation. The current status is that
risk is a notion still strange to main stakeholders. The
Greek practice in performing a feasibility study for a
project draws on investor’s experience and feeling
aided by a preliminary economic study. The main
789
thesis of this paper is that there are alternative
techniques to evaluate investment risk and measure
profitability of a project. A Monte Carlo simulation in
collaboration with a typical Ro-Ro cash-flow model
is implemented to reveal the extent of risk and
provide a useful tool for the assessment of future
investments in Greek Short Sea Shipping.

The objective of this paper is to illustrate behavioural
aspects and a collaborative Delphi-based planning
approach in the maritime transport chain. Therefore,
this paper analyses changes in behavioural routines
and governance structures in the maritime transport
chain using a case study that depicts mutual
projections of expected container trans-shipment
moderated by a neutral third for reducing the
uncertainty in planning within the whole maritime
transport chain. The actors’ different views on
container transport are collected and directly
confronted to an expert panel showing bounded
rationality and thus asymmetric information can be
circumvented. The planning approach shows how
actors’ different internal planning can be improved
and evident to the market. The whole maritime
transport chain expects the future development in
container transport which can be given by using
collaborative Delphi-based planning. As a result, an
overall picture for planning issues can be constituted,
improving both individual planning of the actors and
expected market growth.
