, a full qualification program typically involves five critical stages: Documentation Review: A thorough check of technical specs and system design. Methodology Review: Assessing the scanning strategy and operating procedures. QA System Audit:

Once the test results are analyzed, a final report is compiled documenting the Probability of Detection (PoD) and the accuracy of the defect measurements. Challenges and Future Trends

Provide a "fair basis" for comparing different AUT providers.

By implementing this RP, DNV anticipated that the industry would be able to assess AUT system and procedure suitability on an "equal terms," fostering fair competition and a higher baseline of quality.

Since its release, DNV-RP-F118 has become the industry's go-to standard for AUT qualification, effectively bridging the gap left by its parent standard, DNV-ST-F101 (formerly DNV-OS-F101). Companies specializing in Non-Destructive Testing (NDT) have developed and refined their qualification processes based on these guidelines. Furthermore, advanced software simulation tools like CIVA have incorporated the ability to model AUT inspections and compute POD curves based on the methodologies set forth in DNV-RP-F118.

To reduce costs, the industry is increasingly using CIVA simulation software to model UT inspections. DNV-RP-F118 is evolving to validate these simulations.

Historically, radiographic testing (RT) using X-rays or gamma rays was the standard approach for weld inspection. However, modern pipeline engineering heavily relies on automated ultrasonic testing (AUT), particularly utilizing technologies like and Time-of-Flight Diffraction (ToFD).

Before testing begins, the operator must review the technical documentation, operating methodology, and quality assurance system of the AUT system. 2. Performance Data Assessment

Understanding DNV-RP-F118: The Standard for Qualifying Pipeline Girth Weld AUT Systems

is a DNV recommended practice that outlines the procedures for qualifying Automated Ultrasonic Testing (AUT) systems, specifically used for the inspection of pipeline girth welds. This standard is tightly coupled with DNV-OS-F101 (Submarine Pipeline Systems), providing the validation steps needed to ensure that a chosen NDT (Non-Destructive Testing) system can meet the safety criteria for a specific project. The practice provides a structured approach for both:

Unlike classification society rules (e.g., DNV-OS-E301), which focus on new mooring designs, F118 addresses in-service degradation. It provides:
