The American Petroleum Institute (API) and Association of Oil Pipe Lines (AOPL)’s Research and Development Work Group (RDWG) and PRCI are undertaking a joint industry project to develop pull test strings and protocols to validate and test the performance specifications published for ultrasonic crack detection, electromagnetic acoustic transducer (EMAT), and spiral and circumferential magnetic flux leakage (MFL) in-line inspection (ILI) tools. The purpose of the joint industry project is to assess the current industry specifications and improve ILI crack tool capabilities. DNV GL served as the project manager for Phase I of the joint industry project.
This report summarizes the work completed in Phase I, which covered evaluating test facilities and methods of manufacturing crack-like defects, developing a preliminary defect set design and test protocol, and soliciting ILI vendor support.
