  1. Implementing The Paint Specification in the Performance Standard for Protective Coatings NPCA Virginia Beach June 08 NPCA08

  2. Objective • To provide a review of the requirements as laid out in the IMO PSPC and highlight important aspects NPCA08

  3. The Parties Involved at present Shipyard Ship-owner Productivity/ Environment Performance Coating supplier NPCA08

  4. 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 NPCA08

  5. 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 NPCA08

  6. Tip of the iceberg • A family of regulations • PSPC • Permanent means of access • Cargo tanks • Maintenance • These will change the current compromise solutions NPCA08

  7. 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 NPCA08

  8. Coating Performance Standard Review • Aims of the PSPC NPCA08

  9. Coating Performance Standard Review • Aims of the PSPC NPCA08

  10. 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 NPCA08

  11. 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 NPCA08

  12. The Parties Involved Shipyard Ship-owner Classification Soc. ? Productivity Performance Coating supplier NPCA08

  13. 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 NPCA08

  14. 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 NPCA08

  15. 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 NPCA08

  16. 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

  17. The Paint Specification • The paint specification covers all the processes and defines the standards from: Shop Primer Application Block Painting Post Erection Repairs NPCA08

  18. 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 NPCA08

  19. 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 NPCA08

  20. 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 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 www.safinah.co.uk NPCA08 54

  21. Suggested table of contents and responsibilities for in service Ship owner Maintenance log Inspection log Condition log Class inspection log www.safinah.co.uk NPCA08 55

  22. 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 NPCA08

  23. 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. NPCA08
