Incident Narrative

"ON 12/18/2024 AT APPROXIMATELY 15:20, A PIPELINE TECHNICIAN DISCOVERED OIL ON THE GROUND AROUND FINNEY STATION METER PIPING DURING A ROUTINE STATION CHECK. THE STATION WAS SHUTDOWN AND 26010.02 LONGVIEW TO FINNEY 18-INCH LINE WAS BLOCKED IN. APPROXIMATELY 5 BARRELS OF CRUDE OIL WAS RELEASED ONTO THE GROUND. CONTRACTORS CLEANED-UP FREE PRODUCT AND REMOVED IMPACTED SOIL. THE LINE WAS REPAIRED WITH A MECHANICAL CLAMP AND RESTARTED. AN NDE SCAN WAS PERFORMED AT THE ACCIDENT LOCATION AND NO OTHER ANOMALIES WERE FOUND. THE CAUSE OF THE ACCIDENT IS UNDER INVESTIGATION. THE FAILED SECTION IS PLANNED TO BE CUT OUT AND SENT TO A THIRD-PARTY LAB FOR ANALYSIS. A SUPPLEMENTAL REPORT WILL BE SUBMITTED ONCE THE INVESTIGATION IS COMPLETE. SUPPLEMENTAL & FINAL: DURING THE INVESTIGATION IT WAS DETERMINED THAT THE ACCIDENT OCCURRED ON 16-INCH STATION PIPING FOR THE INBOUND CONTROL VALVE TO THE FACILITY. THE METALLURGICAL ANALYSIS DETERMINED THAT THE FAILURE WAS DUE TO AN INTERNAL CORROSION PINHOLE AT THE 6 O'CLOCK POSITION. THE CAUSE OF THE INTERNAL CORROSION WAS MICROBIAL INDUCED CORROSION (MIC). TO PREVENT REOCCURRENCE, HYDRAULIC CALCULATIONS WERE COMPLETED ON THE INCOMING LINE TO ENSURE THAT ALL DELIVERIES THROUGH THE LINE ACHIEVE TURBULENT FLOW TO ENSURE PROPER FLUSHING. ADDITIONALLY, CONTROL VALVE PIPING WAS REDESIGNED AND CONCENTRIC REDUCERS ON THE LINE WERE REPLACED WITH ECCENTRIC REDUCERS TO PREVENT HOLDING WATER OR SOLIDS IN THE LINE BETWEEN DELIVERIES."
