Narrative
5/20/16 00:35hrs pt the 24" pipe segment from tracy to windmill farms ruptured. The pipeline houston control center scada detected an increase in flow rate and drop in discharge pressure. The pump station immediately shutdown on low suction. The controller took action to shutdown the entire pipeline system and isolate the pipeline. Notifications were made to the field supervisor, the control center supervisor. Personnel were sent to the area of the pump station to locate the exact location of the release. Following the replacement of the failed pipe joint the csfm gave permission to displace the heavy crude oil from the pipeline with light crude oil before an agreed plan of action on the vintage pipe which failed. Inspections and repairs were initiated, along with hydro-static pressure testing of affected segments. The pipeline was re-started with the approval of the csfm on july 19, 2016. The failed pipe was examined at a metallurgical laboratory. Splc's subject matter expert (sme) reviewed the analysis.
