The NORSOK standards were developed in 1994 by the Norwegian petroleum industry to ensure the adequate safety, added value and cost-effectiveness of protective coating systems for petroleum industry developments and operations. NORSOK standards are intended for oil company specifications and serve as references for regulating authorities.

The NORSOK M-501 standard states the requirements for the selection of coating materials, surface preparation, application procedures and inspection for protective coatings to be applied during the construction and installation of offshore installations and associated facilities. It covers paints, metallic coatings and application of spray-on passive fire protective coatings. The aim of the NORSOK M-501 standard is to obtain a coating system that ensures:

• Optimal protection of the installation with minimum need for maintenance

• That the coating system is maintenance friendly

• That the coating system is application friendly

• That health, safety and environmental impacts

are evaluated and documented
