Narrative
During a routine station check at coffeyville station, a pipeline technician identified a leak from the coffeyville loop pig trap. The technician immediately notified pipeline control to shut down the pump. The technician proceeded to isolate the trap to stop the leak and then placed booms to contain the leak. A hazmat response team was dispatched to remediate surface waters and 120 cubic yards of contaminated soil. The remediation was completed on 4/23/13. The trap was isolated for inspection and repairs prior to restarting the line segment. The trap door closure mechanism was subsequently replaced with a different type of closure mechanism and returned to service. Metallurgical analysis identified the o-ring fractured due to tensile overstress from being twisted and pinched at two locations, including the eventual failure origin. The o-ring may have been twisted and pinched during the installation or closure of the door, however, based on the metallurgical analysis and subsequent analysis, we could not identify when and how the o-ring became twisted and pinched.
