HISTORY OF MODERN SHIPPING
Naval Architecture
Naval architecture is an engineering discipline dealing with the design,
construction, maintenance and operation of marine vessels and structures.
Naval architecture involves basic and applied research, design, development,
design evaluation and calculations during all stages of the life of a marine
vehicle. Preliminary design of the vessel, its detailed design, construction,
trials, operation and maintenance, launching and dry-docking are the main
activities involved.
Ship design calculations are also required for ships being modified (by means
of conversion, rebuilding, modernization, or repair).
Naval architecture also involves formulation of safety regulations and damage
control rules and the approval and certification of ship designs to meet
statutory and non-statutory requirements
Wikipedia (http://en.wikipedia.org/wiki/Naval_architecture)
NAVAL ARCHITECTURE
Naval architecture is a facinating and demanding
discipline.
• It is fascinating because of the variety of
floating structures and the many compromises
necessary to achieve the most effective
product.
• It is demanding because a ship is a very large
capital investment and
• because of the need to protect the people on
board and the marine environment.-
SHIP TYPES DUE TO FUNCTION
There are variety of forms. This variation is due to
different demands and the conditions under which
they operate.
• Fishing boats raging from the small local boats
operating by day, to the ocean going ships with
facilities to deep freeze their catches.
• There are vessels to harvest the other riches of
the deep - for exploitation of energy sources,
gas and oil, and extraction of minerals.
• There are oil tankers, ranging from small
coastal vessels to giant supertankers.
SHIP TYPES DUE TO FUNCTION
• Other huge ships carry bulk cargoes such as
grain, coal or ore.
• There are ferries for carrying passengers
between ports which may be only a few
kilometres or a hundred apart.
• There are the tugs for shepherding ships in port
or for trans-ocean towing.
• Then there are the dredgers, lighters and pilot
boats without which the port could not function.
• In a naval port, there will be warships from
huge aircraft carriers through cruisers and
destroyers to frigates, patrol boats, mine
countermeasure vessels and submarines.
SHIP TYPES DUE TO HULL FORMS
•
•
•
The majority of ships are single hull and rely upon
their displacement to support their weight.
In some applications multiple hulls are preferred
because they provide large deck areas without
excessive length.
In other cases higher speeds may be achieved by
using dynamic forces to support part of the weight
when under way. Planing craft, surface effect ships
and hydrofoil craft are examples.
SHIP TYPES DUE TO HULL FORMS
•
Air cushion craft enable shallow water to be
negotiated and provide an amphibious
capability.
• Some craft will be combinations of these
specialist forms.
The variety is not limited to appearance and
function
MATERIALS
The variety is not limited to appearance and
function. Different materials are used –
• steel,
• wood,
• aluminium
• Composites of various types (GRP, FRP
etc).
PROPULSION SYSTEM
The propulsion system used to drive the craft
through the water may be
• the wind,
• but for most large craft is some form of
mechanical propulsion.
POWER GENERATION
The driving power may be generated by
• diesels,
• steam turbine,
• gas turbine,
• some form of fuel cell or
• a combination of these.
POWER TRANSMITION TYPE
The power will be transmitted to the propulsion
device through
• mechanical or hydraulic gearing or
• by using electric generators and motors as
intermediaries.
PROPULSOR TYPE
The propulsor itself will usually be some form of
• propeller,
• perhaps ducted,
• but may be water or
• air jet.
SYSTEMS
There will be many other systems on board means of
• manoeuvring the ship,
• electric power generation,
• hydraulic power for winches and other cargo
handling systems.
FACILITIES IN A PASSENGER SHIP
A ship can be a passenger ship whit several
thousand people on board and remaining at sea for
several weeks. It needs
• electrics,
• air conditioning,
• sewage treatment plant,
• galleys, bakeries,
• shops,
• restaurants,
• cinemas,
• dance halls,
• concert halls and
• Swimming pools.
SHIP TYPES DUE TO HULL FORMS
All these, and the general layout must be
Arranged so that the ship can carry out its
intended tasks efficiently and economically.
NAVAL ARCHITECTURE
The naval architect has not only the problems of
the building and town designer but a ship must
• float,
• move,
• be capable of surviving in a very rough
environment and
• withstand a reasonable level of accident.
NAVAL ARCHITECTURE
It is the naval architect who 'orchestrates' the
design, calling upon the expertise of many other
professions in achieving the best compromise
between many, often conflicting, requirements.
NAVAL ARCHITECTURE
The profesion of a naval architecture is a blend of
science and art :
• Science is called upon to make surethe ship
goes at the
• intended speed
• stable,
• Strong enough to withstand the harsh
environment
NAVAL ARCHITECTURE
The art is in getting a judicious blend of the many factors involved so as to
produce a product that is not only aesthetically pleasing but is able to carry out
its function with maximum effectiveness, efficiency and economy.
Naval architecture is a demanding profession
WHY DO WE NEED TO DESIGN AND PRODUCE
NEW SHIPS?
Ships are industrial structures. They are designed and produced to
fullfill some duties
Why is it needed to design and produce new ships?
To renew the old ships or the ships that complited economical life
with produced with old tecnologies,
To make the fleet bigger or capital more with renewign ships,
To have bigger market share by having new trading lines and any
other cargo type,
To open new markets according to new economical conditions,
To use sources at open seas and make industrial activities,
To support commercial and industrial ships,
To fullfill defence demand of the country.
MISSION DEFFINITION AND
MISSION ANALYSIS FOR SHIP DESIGN
Ships can be divided to 4 categories according their
duties:
1. Conventional ships: Mainly carries cargo and
passengers.
2. Industrial ships: Usually aims to examines and make
use of sources in sea.
3. Service ships: Supports conventional and industrial
ships as well as to make safety of life and goods at.
4. Navy ships: They are armed ships and used to keep
piece of the nation.

MISSION ANALYSIS
BASE OF DUTY ANALYSIS:
1. Requirements of customer/ship owner
2. Restrictions. These two are analysed according to technical and
economical factors.
There are two main group of factors to design a conventional ship:
A - Economical facts:
● Structure of the fleetand number of ships that are planned to
design,
● Aimed route and tonnage,
● Aimed speed,
● Characteristics of cargo and capacity definitions,
● Alternatives for cargo handling, looading and unloading
● Examining and choosign propulsion systems,
● Decide the automation level of engine room,
● Use of the ship with other aimes and type of cargo,
● Investment and capital cost amount,
● Forecasting of freight and changes of it,
● Finance agreement conditions.
