DNV-RP-F118, often cited alongside the offshore service specification , outlines the requirements for demonstrating that an AUT system can reliably detect and accurately size flaws in pipeline girth welds. Traditional radiography (RT) has largely been replaced by AUT in modern pipeline projects due to the latter's speed, safety, and ability to provide three-dimensional data on weld defects. The Core Objective: Probability of Detection (PoD)

Adhering to DNV-RP-F118 ensures that pipeline operators can have high confidence in their subsea infrastructure. By requiring a rigorous, statistically backed qualification, the standard minimizes the risk of catastrophic pipeline failure due to undetected weld cracks or inclusions. dnv-rp-f118

Generating PoD and sizing accuracy curves to prove the system meets the project-specific Acceptance Criteria . The Role of Simulation (CIVA) By requiring a rigorous

DNV-RP-F118 emphasizes that a small number of samples (like 3 or 4) is insufficient to prove reliability. statistically backed qualification
