: Historically, pipelines were checked using X-rays (radiography), but this was slow, hazardous due to radiation, and often missed certain types of cracks. The Solution DNV-RP-F118

Evaluating the quality controls for maintenance and field operations. Performance Data Analysis: Reviewing existing data on detection and sizing accuracy. Final Evaluation: dnv-rp-f118

Establishing not just if a flaw is detected, but how accurately the system can measure its dimensions. Where to Find the Full Text Final Evaluation: Establishing not just if a flaw

Disclaimer: This report is a summary based on the general scope and technical content of DNV-RP-F118. For specific engineering decisions, the full official document provided by DNV should be consulted. To achieve a PoD of 90% with 95%

To achieve a PoD of 90% with 95% confidence, a minimum of 29 samples is typically required for simple assessments. However, DNV-RP-F118 often requires significantly more data to ensure reliability in complex weld geometries. For example, for double V submerged arc welds, the practice recommends at least 91 samples .

Before this RP, the industry lacked a standardized way to prove that an AUT system was reliable enough for critical subsea infrastructure. Use of DNV-RP-F118 allows pipeline operators and contractors to:
