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 international 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 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
  • the coating system is application- and maintenance-friendly
  • health, safety, and environmental impacts are evaluated and documented

We have published a detailed guide that highlights examples of PPG’s protective products for coating systems that have been tested to and comply with the pre-qualification requirements established by NORSOK. Recommended systems that satisfy the defined exposure conditions are also included.
