Incident Narrative
"ON JANUARY 24, 2024, AT APPROXIMATELY 01:57, ENERGY TRANSFER (ET) PERSONNEL WERE NOTIFIED BY GAS CONTROL OF A COMPRESSOR SHUT DOWN AT THE GALVAN G5L CDP COMPRESSOR STATION. THIS STATION IS TIED TO THE G5LTS-8 LINE, WHICH IS A TYPE C GAS GATHERING LINE LOCATED IN WEBB COUNTY. ET PERSONNEL ARRIVED ON SITE AT 02:43 AND NOTICED THAT A UNIT WAS ON FIRE. ET PERSONNEL IMMEDIATELY INITIATED AN EMERGENCY AREA SHUT DOWN BY CLOSING THE FUEL LINE SUCTION HEADER VALVE AND DISCHARGE VALVE AT 02:45, WHICH ALLOWED THE FIRE TO BURN OUT. DAMAGE WAS LIMITED TO THE INDIVIDUAL ENGINE. THE UNIT WITH THE DAMAGED ENGINE WAS ISOLATED FROM THE COMMON HEADER, WHICH ALSO HAS 3 OTHER UNITS CONNECTED TO IT. THE FACILITY WAS STARTED UP AND PUT BACK IN SERVICE ON JANUARY 24TH AT APPROXIMATELY 06:41 ON JANUARY 24TH. THE DAMAGED ENGINE HAS BEEN ASSESSED AND A REPLACEMENT ENGINE HAS BEEN ORDERED. INVESTIGATION REVEALED THAT THE MOST APPARENT CAUSE OF THE INCIDENT WAS THE STARTER/FUEL GAS SUPPLY DEVELOPED A LEAK AT OR NEAR THE VICINITY OF THE SEALCO VALVE. THE START/FUEL GAS LEAKAGE FOUND AN IGNITION SOURCE. THE HIGH HEAT CAUSED THE SEALCO VALVE TO LOSE ITS INTEGRITY AND SEPARATE INTO PIECES. THIS ALLOWED THE 120# OF FUEL GAS TO FUEL THE FIRE."
