The qualification process described in DNV-RP-F118 is rigorous. It is not enough for an AUT system to simply detect a flaw; it must demonstrate the ability to accurately measure the flaw's size, type, and location. 1. Technical Documentation & Procedure Review
Performing multiple passes on these mock-ups to collect ultrasonic data. dnv-rp-f118
: It moves beyond "best guesses" to require statistical evidence of flaw detection. Accuracy is Quantified root opening) [DNV GL
, 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: and location. 1.
The DNV-RP-F118 standard provides guidelines for the geotechnical design of offshore wind turbine foundations, including:
While DNV-RP-F118 provides a clear structure, experts note that achieving "general validity" across different projects can be difficult. Factors like ultrasonic coupling weld geometry material properties
The qualification is specific to the weld profile (bevel angle, root opening) [DNV GL, 2011].
