Narrative
Approximately 2940 bbls of crude oil were released from a tank discharge line. The cause of the failure is still under investigation. This segment has been sent to a lab to undergo metallurgical analysis. A supplemental report will be submitted once the results are received. Costs were determined to exceed the $50,000 reporting threshold at 21:01 mt (9:01pm) on 10/15/2017. As a result, the national response center (nrc) was notified and assigned initial report #1193374 . A follow-up call to the nrc, assigned report #1193539. Supplemental report: the pressure increase on the pipe weld in conjunction with an already reduced stress capacity caused the pipe to prematurely fail along the seam of the pipe. The failure occurred during a coating remediation project of the pipeline, however, the failure location was still buried at the time. Plains has replaced the discharge line from the check valve to the manifold, which is now back in service. Part e, #1 and #3 have been updated to reflect the newly received information. This estimate is based on API 579 level 2 fad (failure assessment diagram) technique in which the material properties of the failed joint were combined with an observed flaw size of more than 4 inches in length and 50% through the wall thickness. Under normal operations this line was buried, providing natural thermal protection in the warmer months. When the line was exposed for the coating remediation project it subjected the line to abnormal temperature swings. As mentioned previously, the discharge line from the check valve to the manifold was replaced above ground. A bypass has also been installed to ensure that the line has a path for any thermal relief in the future. In addition, thermal stress is a physical hazard evaluated on work permits.
