PR186-203813-R01 Literature Review Pipeline Mid-wall Defect Detection and FFS Assessment

A literature review on the current industry understanding of mid-wall cracking and its detection was conducted. A summary of key factors influencing mid-wall cracking and modern integrity management approaches for the phenomenon are summarized. Based on the literature review and subject matter expert interviews, gaps in the published industry knowledge were identified. These gaps will be used to drive work in the direction of backfilling the valuable information that may be used to mitigate the onset of mid-wall cracking and to identify the presence of mid-wall cracking so that the threat can be actively and effectively managed.
