NORSOK standards

The NORSOK standards are developed by the Norwegian petroleum industry to ensure adequate safety, value adding and cost effectiveness for petroleum industry developments and operations. Furthermore, NORSOK standards are as far as possible intended to replace oil company specifications and serve as references in the authorities regulations.

There are forty years of petroleum experience from the Norwegian continental shelf behind the NORSOK standards.

The acronym Norsok originally stands for "the Norwegian shelf’s competitive position" and was introduced in 1994 to cut costs and improve competitiveness on the Norwegian continental shelf.

Standards Norway has signed an agreement with the owners, the Federation of Norwegian Industries, the Norwegian Oil and Gas Association and Norwegian Shipowners´ Association, for the management of the Norsok standards.

Development and maintenance of Norsok standards
The NORSOK directive A-001N states the procedures for the professional work and rules for structuring, writing and approval of Norsok standards. The directive is available in Norwegian only.

Facts about NORSOK
There are currently about 79 national NORSOK standards in active use. 

Recognised standards, both NORSOK and ISO, today form an important basis for the regulations in force on the Norwegian continental shelf, and Norway has so-called function-based regulations, where standards are an important factor in the interpretation of the various regulatory requirements.

The regulations refer to standards that provide more detailed descriptions of how things should be done. About half of these standards are used by the Petroleum Safety Authority as part of regulatory management in the North Sea.

Tripartite cooperation
Standards Norway today facilitates petroleum standardization work by hundreds of Norwegian experts in various committees and working groups nationally and internationally. Petroleum standardization in Norway is a voluntary tripartite cooperation with participants from employers' organisations, employee unions and the government.

Participants from the industry are experts from the operators, suppliers, service companies, the Petroleum Safety Authority and the maritime industry, and the sharing of experience and expertise leads to best practice in the form of standards.

The Sector Board Petroleum Industry ensures overall standardization in the industry through coordination of international standardization work in ISO and CEN and the industry standardization work of Norsok.
