L-002 Pdf | Norsok

Developed by the Norwegian petroleum industry, the NORSOK standards aim to replace individual oil company specifications with a unified set of rules. L-002 specifically targets the layout and design of piping systems

A Gulf of Mexico project used carbon steel per NACE MR0175 but ignored NORSOK L-002’s requirement for HIC testing. After 6 months, wet H₂S caused blistering and stepwise cracking. A follow-up analysis confirmed that L-002’s Annex A requirements (100% HIC testing) would have rejected the batch. norsok l-002 pdf

NORSOK L-002 standard, titled "Piping system layout, design and structural analysis," serves as a critical framework for ensuring safety, cost-effectiveness, and operational efficiency in the oil and gas industry. By providing standardized guidelines for piping systems on offshore installations, L-002 bridges the gap between complex engineering requirements and practical execution. The Purpose and Scope of NORSOK L-002 Developed by the Norwegian petroleum industry, the NORSOK

The standard rigorously defines the placement of safety-critical valves, such as: A follow-up analysis confirmed that L-002’s Annex A

Calculations align with ASME B31.3 Process Piping rules.

Common requirements — Piping design, layout and stress analysis
