A: Typically, a "Competent Person" with at least 5 years of offshore mechanical integrity experience and specific training in the NORSOK standard. Most operators require a Level III NDT inspector or a Chartered Engineer.
For valves and fittings, the threads wear out. A gate valve that opens fine on a bench may have 50% thread depth left. R-001 demands a thread gauge inspection. If the thread engagement is below 75% of original spec, the equipment is scrapped. norsok r001
Far from being a simple checklist, NORSOK R-001—full title "Mechanical Equipment" —is a sophisticated systems engineering methodology that governs how operators like Equinor, Aker BP, and ConocoPhillips can safely and cost-effectively reuse mechanical components ranging from valves and heat exchangers to entire process modules. A: Typically, a "Competent Person" with at least
If you are working on a Norwegian shelf modification project in 2025, assume that R-001 applies. Start your data collection yesterday. And remember: In the world of NORSOK, reuse is not a compromise—it is an engineering discipline. Frequently Asked Questions (FAQ) on NORSOK R-001 Q: Does NORSOK R-001 apply to electrical equipment? A: No. Electrical and instrumentation equipment fall under NORSOK R-002 (Lifting and Transport) or R-003 (Electrical). R-001 is strictly mechanical. A gate valve that opens fine on a
If you are reusing a carbon steel flange originally bolted to a Monel heat exchanger, the flange likely suffered accelerated galvanic corrosion. R-001 requires you to inspect the interface points , not just the component in isolation.
