Narrative
On 4/20/2023 at approximately 18:25, operations received a call from a landowner concerning a petroleum odor. Line was shutdown and isolated. After investigation of the area and excavation of the pipeline, confirmation of the release was determined at 23:15. Approximately 4 barrels of crude oil was released. Clean-up crews removed free product and contaminated soil. Nrc was notified in the event that total costs would exceed $50k which they did not. The line was excavated and pinhole leak was found on a weld. A mechanical plidco clamp was installed. The line was monitored under pressure before being released to normal operations. Plans are underway to purge the line section at the clamp site, cut out the pipe section, replace with welded steel pipe, and have the section with the failure further analyzed by third party lab. The plan is to cut out the pipe and sent it to the lab by the end of first quarter 2024. Supplemental: metallurgical analysis determined the cause of the failure was a surface breaking, circumferentially oriented flaw at the girth weld which consisted of two (2) regions. The first region was an inside diameter surface breaking hydrogen assisted cold crack which initiated in the heat affected zone of the u/s pipe joint which displayed a high carbon equivalent. The second region was a semi-elliptical shaped crack that grew through wall while in service.
