: The RP defines how to document the reliability, repeatability, and accuracy of an AUT system for both detecting and sizing defects.

Published by DNV (Det Norske Veritas), – full title: “Pipe-soil interaction for onshore and landfall pipelines” – fills a critical gap. It provides a unified methodology for assessing how buried and exposed pipelines interact with soil under thermal expansion, axial walking, lateral buckling, and geohazards. This article will dissect the standard, explain its key formulas, compare it to related codes (F109, F110), and explore its practical application in modern pipeline design. dnv-rp-f118

By adopting F118 early in the design phase, operators can save millions in trenching, backfill, and remediation costs – while ensuring safe, reliable operation for decades. : The RP defines how to document the

✅ Integrates with DNV-RP-F101 (corrosion) and ASME B31G, but specifically for cracking . ✅ Covers both wet (H₂S) and dry (CO₂, high pH) cracking environments. ✅ Offers acceptance criteria for crack depth, interaction, and pressure limits. This article will dissect the standard, explain its
