Incident Narrative

THE MARATHON PUMP MECHANICS WHILE ENROUTE TO BOTH THE BROWN BEAR TUL MAINLINE PUMPS FOR PMS, DISCOVER THAT CRUDE OIL IS LEAKING OUT OF THE MECHANICAL SEAL FOR PUMP 4472. IMMEDIATELY THE MECHANICS CALLED THEIR SUPERVISOR, THEN THE SUPERVISOR CALLED THE CONTROL ROOM AND HAD THE PUMP 4472 SHUTDOWN. THE JOHN CRANE SEAL FAILURE WAS DUE TO THE SLEEVE RUN OUT HITTING THE BUSHING, AND HANG-UP ON THE O-RING FROM TRASH OIL AND DEPOSITS IN THE PRIMARY SEAL. THE PRIMARY SEAL WAS RUNNING ON ONE SIDE OF THE SEAL FACE. MARATHON'S INVESTIGATION FOUND THE 0.125"" RESTRICTION ORIFICE WAS INCORRECT INSTALLED IN THE TUBING CONNECTING THE API 65 SEAL POT, WHICH PREVENTED DETECTION OF THE SEAL FAILURE AND RESULTING RELEASE. PRIOR TO RECOMMISSIONING PUMP 4722, FOLLOWING REPAIRS TO THE SEAL, THE API 65 SEAL POT TUBING WAS DISASSEMBLED AND REASSEMBLED CORRECTLY ON FEBRUARY 7, 2020. CORRECTIVE ACTION: MARATHON WILL COMPLETE INSPECTIONS OF SIMILARLY DESIGNED/INSTALLED API 65 (OR LIKE) SEAL FAIL DETECTION EQUIPMENT TO ENSURE PROPER INSTALLATION, DOCUMENTING AND INSPECTION RESULTS AND CORRECTION OF DEFICIENCIES FOUND, ACCORDINGLY (DATE DUE: 8/31/2020). PREVENTIVE ACTION: FORMALIZE PROCEDURES AND TOOLS (CHECKLISTS, CHECKOUTS, ETC.) TO IMPROVE QUALITY CONTROL INSPECTION AND VERIFICATION OF THE PROPER INSTALLATION OF SEAL FAIL DETECTION EQUIPMENT PRIOR TO COMMISSIONING. (DATE DUE: 11/6/2020).
