Some of the key aspects covered in DNV-RP-F118 include:
The document provides the industry-standard methodology for proving that an AUT system can reliably detect and accurately size flaws in pipeline welds. It is most frequently used in conjunction with the (formerly OS-F101) code for submarine pipeline systems. Key Technical Requirements
Reviewing how the system is operated in the field. dnv-rp-f118
DNV itself has conducted extensive research using the RP. Through numerous qualification programs, DNV GL (now DNV) gained valuable experience and published papers analyzing the statistical challenges. These studies confirm the complexity of AUT systems and the importance of a well-designed qualification study to derive meaningful conclusions about a system's true performance.

To ensure these automated systems provide consistent, reliable results, DNV developed a specific recommended practice: .
The primary goal of DNV-RP-F118 is to provide a consistent method for fulfilling the high-level requirements set by (the offshore submarine pipeline standard). It covers: DNV itself has conducted extensive research using the RP
The core objective of this RP is to ensure that the qualification and project-specific validation of any AUT system is conducted according to the requirements of (Submarine Pipeline Systems) and is performed consistently. In essence, the RP sets out to formally document an AUT system’s performance in three critical areas: reliability, repeatability, and accuracy for detecting and sizing defects.
Before any physical testing begins, the technical foundations of the AUT system are audited. This includes:
DNV-RP-F118 is key to using sophisticated acceptance criteria (based on fitness-for-purpose) rather than just workmanship standards.
Modern pipeline construction relies heavily on and Time-of-Flight Diffraction (TOFD) because they provide rapid, two-dimensional cross-sectional imaging without the safety hazards of radiation. However, an advanced AUT system is only as good as its programming, calibration, and operators.
