Incident Narrative

"4-28-2025 AT 14:30 GAS FLOW ON THE TEMA 2001 LINE WAS REVERSED TO GO TO A DIFFERENT THIRD PARTY PIPELINE. 4-29-25 AT 7:01, MEASUREMENT TECH NOTIFIED OPERATIONS OF A POSSIBLE LEAK AT ULY SOUTH. WHEN THE SCOUT FOREMAN ARRIVED THE FOREMAN FOUND THE TEMA 2001 PSV HAD LIFTED. FOREMAN CLOSED VALVE TO THE PSV AT APPROXIMATELY 7:52 AFTER CHECKING LINE PRESSURES. UPON INVESTIGATION, WE FOUND THAT THE BLOCK VALVE BELOW THE PSV HAD NOT BEEN BLOCKED IN RESULTING IN THE PSV LIFT. THE PSV IS USED TO PROTECT THE UBS COMPRESSOR STATION FROM OVERPRESSURE AND IS SET WELL BELOW MAOP OF THE TEMA 2001 PIPELINE. THIS PSV IS NOT NEEDED WHEN GAS FLOW IS REVERSED TO GO TO THE THIRD PARTY. THE ORIGINAL PROCEDURE DID NOT INDICATE THE VALVE NEEDED TO BE IN THE CLOSED POSITION WHILE THE OFFLOAD OF GAS WAS BEING PERFORMED. IN ADDITION THE ORIGINAL PROCEDURE HAS BEEN AMENDED TO REFLECT THE VALVE SHOULD BE CLOSED DURING THE OFFLOAD PROCESS. ALTHOUGH TYPE C GATHERING LINES DO NOT REQUIRE OPERATOR QUALIFICATIONS, WE BELIEVE THIS EMPLOYEE HAS HAD ADEQUATE TRAINING TO PERFORM THIS PROCEDURE. THE EMPLOYEE PERFORMING THIS TASK HAS 30+ YEARS OF EXPERIENCE IN THE FIELD OPERATING VALVES. THE EMPLOYEE HAS ALSO REVIEWED THE AMENDED PROCEDURE."
