1 General
1.1 This standard provides guidelines for establishing minimum requirements for the corrosion protective coatings on steel offshore structures associated with oil and gas production, and on the associated handling equipment. It covers coating materials, coating prequalification test methods and the associated acceptance criteria, surface preparation, coating application, quality assurance and control, and repair methods. It also covers generic protective coating systems, flange corrosion control, fastener coatings, pipe support corrosion control, and SS tubing corrosion control. Offshore structures include metallic offshore and coastal structures such as fixed-leg platforms, TLPs, semisubmersibles, spar platforms, and FPSOs.
1.2 For this standard, corrosion on offshore structures is divided into four zones: atmospheric zone, splash zone, exterior submerged zone, and ballast water tank (internally immersed). The exterior submerged zone also includes subsea facilities, such as valves and manifolds. Each zone may use different protective Coating systems.
1.3 This standard does not include corrosion protective coatings for subsea pipelines, pipeline risers, internal portions of production tubing, drill pipes, and chemical tanks that may be in use on the offshore structure, but does include external protection of the chemical tanks on the offshore structure in the atmospheric zone.
1.4 Passive fire protection (PFP) coatings and nickel- copper alloy (e.g., UNS N04400[Alloy400)]) splash zone sheathings also are excluded from this standard.
2 Terms and Definitions
For the purpose of this standard, the flowing terms and definitions apply.
2.1
Amine blush
Greasy film on the surface of a coating caused by its amine or polyamide curing agent reacting with carbon dioxide (CO2) and water (H2O). (It can greatly interfere with intercoat adhesion.)
2.2
Atmospheric zone
The portion of a marine structure that extends upward from the splash zone and is exposed to sun, wind, water spray, and rain.
