Incident Narrative

ON MARCH 13, 2018 AT 10:58 AM PST, A 4.69 BARREL RELEASE OCCURRED AT THE LEBEC STATION DUE TO A MECHANICAL FAILURE OF THE MAINLINE PUMP SEAL. ALL OF THE PRODUCT WAS CONTAINED IN THE ENGINEERED PUMP PAD AND DID NOT REACH SOIL. THE SEAL FAILURE OCCURRED WHILE A STATION OPERATOR WAS ON SITE AND AS A RESULT, THE PUMP WAS IMMEDIATELY SHUT DOWN AND THE SUPERVISOR AND CONTROL CENTER NOTIFIED. ON THE SAME DAY, RECOVERY AND CLEAN-UP OF CRUDE OIL ON THE PUMP PAD WAS COMPLETED BY 3:30 PM PST AND THE PUMP SEAL WAS THEN REPLACED AND THE PUMP WAS PUT BACK INTO SERVICE AT 4:30 PM PST. A FAILURE ANALYSIS WILL BE CONDUCTED ON THE FAILED SEAL REMOVED FROM THE PUMP AND THE RESULTS WILL BE SHARED WITH ENGINEERING AND FIELD MAINTENANCE STAFF. A SUPPLEMENTAL REPORT WILL BE FILED WITH THE RESULTS OF THAT FAILURE ANALYSIS. SUPPLEMENTAL REPORT: PBF/TORRANCE VALLEY PIPELINE COMPANY (TVP) SENT THE MAINLINE PUMP OUT TO A SPECIALTY SHOP FOR FAILURE ANALYSIS. IT WAS DETERMINED THAT THE SEAL FAILURE WAS THE RESULT OF A COMBINATION OF HIGH TORQUE AND POOR LUBRICATION. TVP WILL REVIEW AND REVISED AS REQUIRED START UP AND SHUT DOWN PROCEDURES TO REDUCE UNNECESSARY TORQUE AND ASSURE PROPER WARM UP OF LUBRICANT AND MECHANICAL PARTS, CHECK ALL FLUSHING LINES FOR ANY OBSTRUCTIONS AND UPGRADE THE BEARING U-CUP FOLLOWER WITH AN UPGRADED ALLOY TO AVOID CORROSION.
