  1. The Importance of Specification Writing Neil Pittman Sr. Corrosion Engineer Lake Superior Consulting npittman@lsconsulting.com

  2. WHY? • A specification becomes a legal part of the contract. • Defines what is to be done. • Identifies what coating to use. • Removes assumptions and miscommunication. • Promotes Cooperation. • Good paints fail.

  3. WHO? • Employ a coating engineer. • Hire a consultant. • Send an employee to NACE CIP 1. • Have a corrosion engineer write it. • Plagiarize • Munger, Charles – Corrosion Prevention by Protective Coatings, Houston: NACE International, 1999. • NACE International • SSPC • Coating manufacturers’ literature

  4. WHEN? • Send specification out with bid package. • Review at pre-bid meeting. • Review at prejob meeting. • Train inspectors and applicators.

  5. What?

  6. PURPOSE This section describes what items/assets are covered by this painting specification and when to use this specification. It also covers what generic types of coatings are applicable: • Epoxies • Urethanes • Zinc rich • Galvanizing • Powders • Multi-coat systems

  7. SCOPE The Scope is different than the purpose. The scope goes into details about operating temperatures, locations and desired results.

  8. DEFINITIONS • Should • Shall • May • Can • NACE, SSPC • DFT • WFT • Etc.

  9. REFERENCES • NACE • ISO • ASTM • API • CSA • SSPC • Proprietary Procedures

  10. SAFETY • PPE • Glasses • Hard hats • Shoes • Fall protection • Respirators • Abrasive blasting • Guards • MSDS • LOTO

  11. REQUIREMENTS • Applicator qualification • Proprietary • NACE • SSPC • Applicator furnished equipment, consumables and labor • Inspection • Quality program

  12. COATING SELECTION • How? • Service life • Service Conditions • Temperature • Water • Onshore/Offshore • UV • Chemicals • Substrate • Constraints

  13. SURFACE PREPARATION • Inspection • Soluble Salts • Pre-cleaning • Atmospheric conditions • Equipment requirements • Blotter test • Abrasives • Cleanliness • Anchor profile • Blowdown

  14. COATING APPLICATION • Storage • Preheating • Dehydration • Mixing and thinning • Pot life • Method • Stripe coat • WFT • Overlap • Visual inspection • Curing • Recoat window • DFT • Holiday detection

  15. INSPECTION The inspection section will outline what measurements must be taken and what are acceptable results. • ITP • Surface preparation • Application • Visual • DFT • Cure • Holiday detection

  16. ITP

  17. REPAIRS • Size • Low DFT areas • Repair material • Stripping • Surface preparation • Cure • Heating

  18. DAILY PRODUCTION REPORT • Every measurement that is required by the specification • Dates and times • Tally • Signed by 3rd party inspector • Checklist • Benefits the applicator

  19. CONCLUSION • Is this a large task? • Is it an important task? • How much does a specification cost? • Now • Later • Is it OK to plagiarize ideas?
