Standard NORSOK S-006 is based on international standards to which it adds other key requirements taking into account needs and impact of the oil industry. Standard NORSOK S-006 can be integrated together with OHSAS 18001 and ISO 14001. The certification is recommended to all companies operating in the oil industry that aim to improve occupational safety and health, while minimizing the environmental impact of their business activities.

The worldwide oil and gas sector faces numerous challenges from global supply chains, which may be a challenge for procurement professionals negotiating regulatory and commercial concerns.

The Oil and Gas network, formerly Achilles JQS and Achilles FPAL, connects thousands of pre-qualified global suppliers in a single, user-friendly platform.

The joint qualification system meets with international Oil and Gas standards NORSOK S006 and IOGP 423 through renewable energy commodity codes and environmental, social, and corporate governance standards (ESG), while also aiding the energy transition to a clean green future.

This standard defines the principles and structure to ensure that equipment and systems are kept preserved during all phases of the project, before taken into use.

NORSOK standards are administered by NTS (Norwegian Technology Standards Institution).

The purpose of this industry standard is to replace the individual oil company specifications for use in existing and future petroleum industry developments, subject to the individual company's review and application. The NORSOK standards make extensive references to international standards.

Where relevant, the contents of this standard will be used to provide input to the international standardisation process. Subject to implementation into international standards, this NORSOK standard will be withdrawn.
