Cause detail: DEFECTIVE OR LOOSE TUBING OR FITTING
Cause detail: THE OPERATION CONTROL CENTER (OCC) WAS NOTIFIED ABOUT A RELEASE AT THE GUARDIAN PEAK INJECTION PUMP SITE. OPERATOR ARRIVED ON-SITE AND OBSERVED APPROXIMATELY 5 BARRELS OF CRUDE OIL WERE RELEASED TO THE GROUND. THE RELEASE ORIGINATED FROM A 1-INCH THREADED DRAIN VALVE AND A 3/8-INCH TUBING LINE DISCONNECTING FROM THE PRESSURE TRANSMITTER. THERE WERE NO INJURIES, AND THE SITE WAS CLEANED UP AND REPAIRED PROMPTLY. INVESTIGATION FINDINGS INDICATE THE 3/8-INCH TUBING LINE WAS NOT INSTALLED CORRECTLY CAUSING IT TO DISCONNECT FROM THE PRESSURE TRANSMITTER. IT IS SUSPECTED THE TUBING INSERTION DEPTH INTO THE FEMALE NPT FITTING WAS INADEQUATE OR MISALIGNED PRIOR TO COMMISSIONING. THIS RESULTED IN THE TUBING LINE SHEARING INSIDE THE COMPRESSION FITTING, CAUSING IT TO DISCONNECT FROM THE PRESSURE TRANSMITTER, LEADING TO THE RELEASE OF CRUDE OIL. THE 1-INCH THREADED DRAIN VALVE WAS A VERY MINOR SOURCE OF THE RELEASE. THE GUARDIAN PEAK INJECTION PUMP SKID DESIGN DOCUMENTS SPECIFIED THE USE OF SINGLE-PIECE CONSTRUCTION BALL VALVES TO BE INSTALLED AS VENTS AND DRAINS. THE SKID WAS DELIVERED WITH THREE-PIECE THREADED BALL VALVES INSTEAD. THE 1-INCH THREADED DRAIN VALVE DISPLAYED EARLY SIGNS OF FAILURE WHEN IT EXPERIENCED A SMALL LEAK ON THE SUCTION SIDE OF THE VALVE. TO PREVENT REOCCURRENCE, THE 3/8-INCH TUBING LINE WAS REMOVED FROM THE PRESSURE TRANSMITTER, AND THE PRESSURE TRANSMITTER WAS INSTALLED ON TOP OF THE PIPE. DELEK HAS REPLACED TWENTY-THREE (23) 1-INCH THREADED BALL VALVES WITH NEW SINGLE-PIECE CONSTRUCTION BALL VALVES. ADDITIONALLY, DELEK WILL DEVELOP AND IMPLEMENT TRAINING THAT INCLUDES THE REQUIREMENT TO DETACH PROCESS TUBING AND INSPECT FITTINGS AND INSERTION DEPTH ON UNITS PRIOR TO COMMISSIONING.
