However, transitioning to advanced ultrasonic technology introduces a vital question: How do pipeline operators prove that an automated inspection system is reliably identifying and sizing critical defects?

However, an AUT system is only as good as its validation. Without a standardized, rigorous qualification process, results can vary, leaving room for costly and dangerous errors. This is where DNV-RP-F118 enters the picture. Officially titled "Pipe Girth Weld Automated Ultrasonic Testing System Qualification and Project Specific Procedure Validation," this recommended practice (RP) from DNV provides a uniform, globally recognized framework for ensuring that any AUT system used on a pipeline project meets the highest standards of reliability, repeatability, and accuracy. dnv-rp-f118

The DNV-RP-F118 standard provides guidelines for the geotechnical design of offshore wind turbine foundations, including: This is where DNV-RP-F118 enters the picture

The operator must demonstrate that the AUT system has a history of successful performance. This involves presenting data regarding: Detection capabilities. Defect sizing accuracy [DNV GL, 2011]. 3.3. Practical Test Welds (Defective Welds)

Because physical qualification is time-consuming and expensive, industry professionals often use simulation tools like CIVA NDT Software to augment the process. Simulation can: Predict probe coverage and beam behavior. Help design calibration blocks.

is more than just a set of guidelines; it is the foundational quality assurance document for automated ultrasonic testing in the offshore pipeline industry. By providing a clear, auditable, and repeatable process for qualifying AUT systems and validating their use on specific projects, the RP ensures that the critical welding in submarine pipelines is inspected with the highest possible level of confidence. For any engineer, project manager, or NDT specialist working in the offshore energy sector, a thorough understanding of this recommended practice is essential for ensuring pipeline integrity, safety, and regulatory compliance.
