Incident Narrative
AN IN-LINE PRESSURE RELIEF CHECK VALVE, FOR THERMAL PROTECTION OF THE OUTGOING LAUNCHER TRAP, WAS BEING REPLACED BECAUSE IT HAD FAILED DURING THE ANNUAL INSPECTION AND TEST. DURING THE CHANGE OUT OF THE IN-LINE PRESSURE RELIEF, THE RELIEF LINE DISCHARGE 1/2"" BALL VALVE CONNECTED TO THE TOP OF THE 20"" MAINLINE ABOVEGROUND PIPING REMAINED IN THE OPEN POSITION, ALLOWED THE RELEASE. AN OPERATOR QUALIFIED KOCH PIPELINE EMPLOYEE PROPERLY ISOLATED THE UPSTREAM PIPING TO THE IN-LINE RELIEF, BUT FAILED TO CLOSE THE DISCHARGE 1/2"" BALL VALVE THAT WOULD HAVE ISOLATED THE DOWNSTREAM PIPING OF THE IN-LINE RELIEF. UPSTREAM PIPING WAS REMOVED FIRST WITHOUT ISSUE BUT DURING REMOVAL OF THE IN-LINE RELIEF, PIPELINE PRESSURE FROM THE DOWNSTREAM SIDE WAS DIRECTLY AGAINST THE IN-LINE RELIEF AS IT WAS UNSCREWED, FORCING THE IN-LINE RELIEF TO SEPARATE FROM THE TUBING CAUSING THE RELEASE. THE AMOUNT OF SOIL REMEDIATED DUE TO IMPACT WAS APPROXIMATELY 100.32 TONS.
