Narrative
(updated 12/10/2018) at approximately 18:27 on 11/29/2016, enterprise's control room noticed a pressure drop on the east red pipeline, line id 603. At approximately 18:29 a member of the public called pipeline control to notify them of a fire in the vicinity of an enterprise pipeline near mp 192.� the line was shut down at 18:30 and the rupture segment was blocked in by pipeline control at valve locations mp 176.75 and mp 198.64.� � at approximately 18:36 a remote valve was closed at mp 190.06. At approximately 19:11 a manual valve was closed at mp 193.57. These valve closures were performed to further isolate the line. � operations arrived at the rupture location at approximately 19:26 and confirmed that there was a rupture and fire on the east red pipeline. The fire was monitored as it continued to burn throughout the night until the fire terminated at approximately 19:54 on 11/30/2016. The emergency phase was declared over at approximately 20:00 on 11/30. � after assessments were made, 150 feet of the line was replaced on 12/5/2016 and the line was restarted after approval from PHMSA on 12/7 at approximately 12:58. � a metallurgical analysis was performed at kiefner and associates, inc. (kiefner) to determine the cause of the failure and for evaluation of the pipe material properties. The metallurgical analysis determined that the pipeline �rupture was due to external near-neutral stress corrosion cracking (scc) along and adjacent to the erw seam. The scc was approximately 14 inches long with a maximum depth of 0.100 inch, or about 50% of the wall thickness at the location of the erw seam. � enterprise conducted hydrostatic testing of the line segment where the rupture occurred in 2017. The test results were reviewed with PHMSA central region and pipe line segment was returned to routine operations without restrictions.
