Incident Narrative
ON MAY 13, 2023 AT 10:50AM (MDT) ONEOK PIPELINE CONTROL RECEIVED A CALL FROM A 3RD PARTY OPERATOR WHO REPORTED A POTENTIAL ICE BALL AT ONEOK LINAM RANCH METER SKID. A ONEOK OPERATOR WAS DISPATCHED AND ARRIVED ON SITE TO DISCOVER A RELEASE ON THE ONEOK LAUNCHER DOOR. THE LAUNCHER WAS ISOLATED AND EVACUATED OF PRODUCT. UPON INVESTIGATION, THE OPERATOR FOUND THE LAUNCHER DOOR O-RING HAD FAILED. THE O-RING WAS REPLACED, PRODUCT REINTRODUCED TO THE LAUNCHER WITH THE OPERATOR REMAINING ON SITE TO ENSURE NORMAL OPERATIONS. ONEOK REVIEWED PRESSURE TRANSMITTER DATA AND DETERMINED THE O-RING FAILURE LIKELY STARTED AT APPROXIMATELY 5:50 PM ON MAY 12TH. UPDATE: ONEOK SUBMITTED THE FAILED O-RING TO A THIRD PARTY FOR ANALYSIS. THE THIRD PARTY ANALYSIS DETERMINED THE O-RING FAILED DUE TO A DECOMPRESSION EVENT AND DID NOT FIND ANY INDICATION OF O-RING MATERIAL DEGRADATION. THE O-RING MATERIAL ITSELF, AS COMPARED TO AN EXEMPLAR, APPEARED TO HAVE MAINTAINED ELASTICITY, HAD APPROPRIATE HARDNESS, APPROPRIATE CHEMICAL ANALYSIS, AND A 1.1 PERCENT DEVIATION IN THE O-RING CIRCUMFERENCE MEASUREMENT. THE LAB WAS NOT ABLE TO DETERMINE THE CAUSE OF THE DECOMPRESSION EVENT. ONEOK VERIFIED THE O-RING WAS INSTALLED PER ONEOK'S PROCEDURE.
