Incident Narrative
"ON 5/17/2021 AT 9:43 AM, GULF COAST HELICOPTERS WAS FLYING THE SAHI LINE AND REPORTED A LEAK ON THE 24"" SWEENY FRAC LAUNCHER. FIELD TECHNICIAN RESPONDED TO THE VALVE SITE AND IMMEDIATELY SAFELY ISOLATED THE 24"" LAUNCHER BY CLOSING SWEL1-B & SWEL1-D VALVES ISOLATING IT FROM MAINLINE OUTLET. AFTER LAUNCHER WAS VENTED SAFELY WITH 0 PSI, THE TATTLETALE WAS REMOVED TO OPEN CLAM SHELL. AFTER OPENING THE LAUNCHER DOOR, TECHNICIAN FOUND THE O-RING DETERIORATED AND NO LONGER INTACT. TECHNICIAN REPLACED WITH A NEW O-RING AND LAUNCHER DOOR WAS CLOSED AND SEALED. AS A CORRECTIVE ACTION, THE DAMAGED O-RING WAS REPLACED WITH THE NEW ONE. INVESTIGATION REVEALED THAT THE PROBABILITY OF LEAK COULD BE DUE TO EITHER INCORRECT MATERIAL OF CONSTRUCTION OR IMPROPER INSTALLATION(PINCHED DURING INSTALLATION) OR DEBRIS ON THE O-RING AFTER PIGGING (WEAR AND TEAR). THE CAUSE IS INDETERMINABLE."
