The Parties Involved
A paint specification is in many ways a compromise:
– It has to meet with the yards building procedures,
environmental and productivity requirements
– The shipyard is the customer of the coating manufacturers
and they have to be competitive on standards as well as
price
– It has to match the paint suppliers product range.
The PSPC is in effect making the compromise
redundant

Coating Performance Standard Review
The Performance Standard for Protective Coatings (PSPC)
provides the technical requirements for protective coatings in
dedicated sea water ballast tanks of all types of ships of 500 gt
and greater and double sided skin spaces on bulk carriers of
150m and greater in length.
It will be mandatory and is intended to be included as
amendments to SOLAS regs II-1/3-2 and XII/6
It is also recommended to be applied where possible to items,
not integral to the structure e.g. ladders, platforms – Permanent
means of access

These will change the current compromise solutions

Coating Performance Standard Review
Aims of the PSPC
– to provide a 15 year life for ballast tank coatings over which
it is defined as in being ‘good’ condition.
– ‘Good’ condition is defined in resolution A.744(18) and is
condition with only minor rust spotting”
( Note: this is different to IACS definition)
“
– Better coating systems with reduced maintenance
– Improved safety at sea

Coating Performance Standard Review
Entry into force
The proposals will apply to the aforementioned types of
vessels:
– For which the building contract is placed on or after 1st July 2008,
or
– In the absence of a building contract, the keels of which are laid or
which are at a similar stage of construction on or after 1st January
2009, or
– The delivery of which is on or after 1st July 2012

Coating Performance Standard Review
Entry into force
However IACS are applying the proposals on
ratification to tankers ( L > 150m) and bulkers
(L > 90m) under the Common Structural Rules (CSR)
for contracts signed from December 8th 2006
It is expected that the first new building classed
under the above rules will begin building in the
second half of 2007

Coating Performance Standard Review
Main Elements of the PSPC:
– Design of a specification and coating system
– Coating System approval
– Definition of inspection procedures
– Production of a Coating Technical File (CTF) which records all
aspects of the process
– Verification of compliance

The Paint Specification
The paint specification is at the heart of the PSPC
and covers:
–
–
–
–
–
–
–
Primary and Secondary surface preparation standards
Steel profile range
Cleanliness of surfaces prior to coating
Soluble salt limits
Steel condition
Thickness and number of coats
Environmental conditions allowed
www.safinah.co.uk
NPCA08
14
The Paint Specification
The paint specification applies to the coating system
that has been selected
Selection of the coating system takes into account
the service conditions and planned maintenance
All coatings to be epoxy based or equivalent and
consist of multi-coat systems of contrasting colour
The top coat to be a light colour
www.safinah.co.uk
NPCA08
15
The Paint Specification
All coatings to be pre-qualified by:
– A method corresponding to a specified test procedure or
equivalent ( now Annex 1), cross test with shop primer or…
– Documented field exposure with a final condition of “GOOD”
after 5 years
Non Annex 1 test must show equivalent testing
procedures and needs.
A Statement of Compliance or Type Approval
Certificate to be issued by a third party - independent
of the coating manufacturer

NPCA08
16
The Paint Specification
The paint specification covers all the processes and
defines the standards from:
Shop Primer Application
Block Painting
Post Erection Repairs
www.safinah.co.uk
NPCA08
17
The Paint Specification
• The painting process at each stage can be separated
into the following simple processes:
– Cleaning the surface
– Preparing the surface
– Coating the surface

18
The Paint Specification
The main elements of the specification in the PSPC are already
being carried out in many shipyards and have been for a
number of years
The main items that are new are :
– A Coating Technical File has to be produced by the shipyard
– All inspectors are to be qualified to a recognised standard
– Increased inspection and prescriptive inspection and data collection
– Audit by class

Suggested table of contents and
responsibilities for New build
YARD
– A statement of agreement
between Owner/yard and paint
company for this contract
– Paint specification as issued by
yard including key criteria and
data sheets
– A summary or full log of work
carried out by yard/coating
inspector - one for each tank
and Non-conformity/repair
summary log for each tank including verified inspection
reports
– Statement of conformance
www.safinah.co.uk
NPCA08
– Copy of type approval
certificate or statement of
compliance
– Yard procedures (for inspection
and repair) audit certificate from
class (includes application ).
Paint Company
– Planned maintenance
procedures for in service
Class Soc.
– Sign off as approved

Ambiguities
There are many ambiguities in the standard:
–
–
–
–
–
Salt measurement
90:10 rule
Area judgement and other subjective elements
CTF detail and content
Products approved through testing – will they last 15 years target
life
– What happens if they do not
There are some guidelines
– PR34 from IACS
– IACS guidance notes
Maintenance requirements
Costs of implementation
IACS members not acting in harmony – adding costs

56
Conclusions
Needs a bedding in period
Needs a cool and calm interpretation
In the wrong hands can considerably add to costs.
Places a clear increased burden on yards
It is going to get worse before it gets better.
