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.NORSOK-Standard-M-650-certification

The standard dictates specific parameters for certifying the necessary facilities and equipment, confirming it functions according to the requirements to manufacture the specified grades. The manufacturer must also have significant experience in producing the qualifying material.  Testing in accordance to requirements set forth in the standard must be made available for review along with the established Manufacturing Summary which details each step of the manufacturing process from begin to end. Qualifications must be certified through a 3rd party witness (EN10204:3.2).

They reference internationally recognized standards while adding requirements found to be effective in battling the stringent environment and stress of the North Sea. .
