Incident Narrative

ON JUNE 19TH, 2019 AT 2:40 PM A CRUDE OIL LEAK WAS DISCOVERED AT THE METER ON THE WEEMS STATION #2 IMO PUMP SUCTION PIPING. THE #2 IMO PUMP IS A CRUDE INJECTION PUMP FOR THE WT-10 PIPELINE. THE SUCTION PIPING/METER WERE OUT OF SERVICE (AND ISOLATED) AT THE TIME, SO THE LEAK AT THE METER ALLOWED THE SUCTION AND METER PIPING TO DRAIN DOWN IN THE AREA. THE SPILL VOLUME WAS ESTIMATED AT 36 GALLONS. PERSONNEL DRAINED DOWN THE REMAINING CRUDE IN THE METER AND SUCTION PIPING SYSTEM AND CLEANED UP ALL THE SPILLED CRUDE. THE #2 IMO PUMP IS ROUTINELY OPERATED AS PART OF THE CRUDE INJECTION SYSTEM INTO WT-10 AT THE WEEMS STATION. DUE TO A FAILURE OF THE #2 IMO PUMP IN JANUARY 2018, THE SUCTION PIPING AND METER SYSTEM WERE ISOLATED UNTIL REPAIRS COULD BE MADE. DUE TO SPARE PARTS ISSUES, THE REPAIRS TO THE PUMP HAD NOT BEEN COMPLETED AFTER MORE THAN A YEAR AND A HALF. BECAUSE THERE WAS NO REGULAR FLOW IN THE SYSTEM, ACCELERATED INTERNAL CORROSION IN THE BOTTOM OF THE METER OCCURRED UNTIL THE METER BODY FAILED. THE CORRECTIVE ACTIONS FOR THIS INCIDENT ARE AS FOLLOWS: * THE FAILED METER WILL BE REPLACED AND THE SUCTION PIPING SYSTEM WILL BE EVALUATED TO ENSURE PROPER INTEGRITY OF THE SYSTEM BEFORE IT IS RETURNED TO SERVICE (AFTER THE #2 IMO PUMP IS REPAIRED) * REINFORCE WITH THE FIELD PERSONNEL THAT THE ISOLATED PIPING SYSTEM SHOULD HAVE BEEN VIEWED AS A DEAD-LEG SINCE THE PUMP REPAIR DID NOT OCCUR IN A TIMELY FASHION. IF THE SYSTEM WOULD HAVE BEEN RECOGNIZED AS A DEAD-LEG, THE PIPING AND METER SYSTEM WOULD HAVE BEEN DRAINED DOWN AND PURGED TO PREVENT INTERNAL CORROSION.
