Narrative
The pipeline was operating at steady state prior to the event at approximately 10,000 bph. No abnormal operating conditions occurred immediately prior to the event. The pipeline controller via scada received an alert of high flowrate and low discharge pressure. The pipeline was promptly shutdown and remotely operated valves closed. Upon investigation it was discovered that pipeline long seam had split on top of the pipe. Further metalurgical analysis determined it was a damaged skelp edge during manufacturing that caused a lack of bonding. - see analysis attached. Removed part a #10 as instructed by email of piyali talukdar on 2/28/13. Supplemental/final (02/11/2020) updated g5-1 to remove "under investigation"
