Incident Narrative

AT APPROXIMATELY 9:30 ON 9/14/2018 A SUSPECTED RELEASE WAS DISCOVERED BY 3RD PARTY OPERATOR AROUND THE LACT UNIT AT THE ADVANTAGE DELIVERY POINT OFF OF THE PECOS CROSSING 12"" PIPELINE. THE CONTROL CENTER WAS NOTIFIED AND THE STATION WAS SHUT DOWN WHILE LOCAL COMPANY OPERATIONS PERSONNEL WERE DISPATCHED TO THE LOCATION TO INVESTIGATE. AFTER ARRIVING ONSITE A RELEASE OF APPROXIMATELY 16 GALLONS OF CRUDE OIL WAS CONFIRMED FROM THE LACT UNIT. TX RRC WAS NOTIFIED AT 11:30 AND CASE NO. 1837 WAS ASSIGNED. THE RELEASE WAS CAUSED BY A CRACK IN THE THREADS OF A 1/4 PIPE NIPPLE ON THE SAMPLER PROBE AT THE CUSTODY TRANSFER METER. THE NIPPLE WAS REPLACED AND THE LACT UNIT WAS RETURNED TO SERVICE AT APPROXIMATELY 13:09 ON 9/14/2018. ALL CONTAMINATED SOIL WAS REMOVED FOR PROPER REMEDIATION. FURTHER INVESTIGATION DETERMINED THAT THE NIPPLE FAILED DUE STRESS FROM VIBRATION WHICH WAS CAUSED BY THE DIFFERENTIAL SETTINGS BETWEEN METER BACK PRESSURE VALVE AND INCOMING PIPELINE PRESSURE CONTROL VALVE WHILE PROVING OPERATIONS TOOK PLACE ON THE METER. TO PREVENT RECURRENCE THE INCOMING PRESSURE CONTROL VALVE AND FLOW WILL BE ADJUSTED PRIOR TO PROVING TO PREVENT VIBRATION. ADDITIONAL SUPPORT WAS ALSO INSTALLED TO THE SAMPLER CONNECTION TO PREVENT VIBRATION.
