NORSOK R-001 is an industry standard developed by the Norwegian petroleum industry to ensure that reused mechanical equipment maintains the same safety and reliability levels as new equipment. It replaces the older NORSOK R-CR-001 and falls under the broader NORSOK family (R stands for "Reuse").

NORSOK R-001 modifies the API or ISO standard by introducing "exceptions and clarifications" tailored to North Sea regulatory environments (such as the Norwegian Petroleum Directorate guidelines). These modifications typically involve stricter non-destructive testing (NDT) requirements, more conservative safety factors, and specific requirements for electrical control systems (often tying into ). 6.

– Forces suppliers to provide detailed documentation (ITP, DCR, O&M manuals) and follow strict qualification processes.

Stringent and testing procedures are required before equipment is installed. This includes factory acceptance tests (FAT) and, upon installation, site acceptance tests (SAT) to verify performance. Relationship to Other Standards
