ExxonMobil SENT test method and application to Strain-Based Design

This paper describes the details of the ExxonMobil SENT test procedure and its application to carry out TSC predictions for SBD. Particularly, the paper covers the following aspects: (1) test procedure including analysis and interpretation of results; (2) validation of selected specimen geometry through comparison with data from pipe Full-Scale Tests (FST); (3) use of the CTOD-R curve as input to the ExxonMobil TSC prediction model; (4) finally, recent challenges related to crack path deviation are discussed with potential ways to address this issue.
