The overall objective of the program is to reduce the uncertainty of Automated Ultrasonic Testing (AUT) detection and sizing accuracy with the goal of dramatically improving the predicted reliability of pipelines in the early design stage. This will be accomplished by the following manner: 1) Develop a methodology for quantification of AUT systems, 2) Advance and quantify AUT systems image-capture capabilities, 3) Quantify the performance of multiple AUT systems and establish a guidance document, 4) Implement the quantification methodology in field tests and guidance document in Reliability Based Design and Assessment (RBDA) standards. The deliverables for this program will include a methodology to quantify imaging capabilities and AUT systems, probability of detection (POD) and sizing accuracy curves for multiple representative systems, guidance for AUT capabilities and ECA/strain based design approach applicability, and technical justification for modifications of the current requirements for AUT quantification trails demanded by the global practices of majors companies and codes. |
