Precision in Every Pulse: A Guide to DNV-RP-F118 for Pipeline Girth Welds For operators managing aging assets or complex subsea

DNV-RP-F118 serves as the industry benchmark for conducting leak detection surveys using wireline technology. It moves the process beyond simple "guesswork" by establishing a rigorous framework for data acquisition and interpretation. For operators managing aging assets or complex subsea pipelines, adhering to this RP is essential for maintaining integrity and preventing environmental damage. The pipeline’s capacity is measured by its tolerable

Enlarge the population of flaws used for PoD curves, making the statistical results more robust without the cost of welding hundreds of physical samples. Why This Standard Matters

Because ground movement imposes displacement-controlled loads (not force-controlled), F118 pivots from stress-based to strain-based design . The pipeline’s capacity is measured by its tolerable tensile/compressive strain—typically governed by local buckling, wrinkling, or girth weld fracture.

DNV-RP-F118 represents a mature, risk-informed evolution in pipeline geohazard engineering. By moving away from uniform safety factors toward site-specific, strain-based assessments, it enables operators to safely manage ground movement threats while avoiding over-conservative designs. For any pipeline crossing active geological terrain—whether 1,000 meters subsea or 1 km inland—this RP is an essential reference for balancing safety, integrity, and economic feasibility.
