Incident Narrative

ON DECEMBER 22, 2016 AT APPROXIMATELY 21:25 CST, AN EDMONTON CONTROL CENTER (ECC) OPERATOR NOTICED THE SUMP TANK LEVEL BEGINNING TO RISE AT KEY STATION. AT 21:45 CST THE SUMP RUNNING ALARMS ALERTED. THE ECC NOTIFIED ON-CALL PERSONNEL TO PHYSICALLY CHECK KEY STATION LINE 59 SUMP TANK. ECC ISOLATED KEY STATION AT 21:53 CST DUE TO THE CONTINUAL RISE IN THE SUMP TANK LEVEL. THE UNIT PUMP SEAL FAIL ALARM OCCURRED AT 21:59 CST. THE ENBRIDGE ELECTRICIAN ARRIVED ON SITE AND ACKNOWLEDGED THE UNIT PUMP SEAL FAIL ALARM AT 23:54 CST IN THE ELECTRICAL BUILDING. ON DECEMBER 23, 2016 AT APPROXIMATELY 00:15 CST, THE ELECTRICIAN WENT INTO THE PUMP BUILDING AND DISCOVERED APPROXIMATELY 12.5 BARRELS OF CRUDE OIL ON THE PUMP BUILDING FLOOR. UPON INVESTIGATION, THE CAUSE OF THE FAILURE WAS DETERMINED TO BE AN INBOARD SEAL FAILURE ON LINE 59 UNIT 2 DUE TO IMPROPER INSTALLATION OF THE SHIM KIT. THE FULL SHIM KIT WAS INSTALLED, WHICH INCREASED TENSION ON THE INBOARD SEAL FACES. THIS EXTRA TENSION CAUSED HEATING ON THE SEAL FACES RESULTING IN DETERIORATION AND EVENTUALLY THE INBOARD SEAL FAILURE. CLEAN-UP OF KEY STATION LINE 59 PUMP BUILDING WAS COMPLETED ON DECEMBER 24, 2016. IT IS ESTIMATED THAT 12.05 BARRELS WAS RETURNED TO THE SYSTEM AND THE REMAINING 0.45 BARREL MIXTURE OF OIL AND WATER FROM STEAM CLEANING WAS PROPERLY DISPOSED OF AT A DESIGNATED DISPOSAL FACILITY. ECC DE-ISOLATED KEY STATION ON DECEMBER 23, 2016 AT 02:26 CST. THE UNIT WAS LOCKED OUT UNTIL THE SEAL WAS REPLACED ON JANUARY 11, 2017.
