Norsok R001 Jun 2026
Pressure-retaining equipment (including heat exchangers), centrifuges, cyclones, and atmospheric tanks.
Mistake: "Our flanges are small, so we didn't test them." NORSOK R-001 has no "small parts" exemption. Bolts, nuts, and small forgings must be tested or supplied with certified mill test reports showing low-temperature impact values.
It specifies used in offshore petroleum facilities, including: norsok r001
✅ Design code accepted by operator and Norwegian authority (DSB for pressure) ✅ Material meets M-001 + R-001 sour service rules ✅ PWHT performed where required (beyond base code) ✅ 100% NDE on all critical welds (not just spot) ✅ Hardness testing completed (especially sour service) ✅ PMI done for alloys and cladding ✅ Hydrotest witnessed and documented ✅ Full traceability from mill to final assembly ✅ Marking per R-001, not just code requirements ✅ Storage preservation plan in place (if not installed immediately)
Compliance with is validated through rigorous engineering and documentation. Key aspects include: 1. General Design and Engineering Consult a certified NORSOK lead auditor or your
While separate standards handle specific pressure vessel codes, R-001 outlines general mechanical integration for:

You cannot reuse a pipe spool if you don't know where the original field welds are. R-001 requires weld maps that correlate to NDT results. If the welds aren't traceable, the spool is rejected.
