Incident Narrative
"AT APPROXIMATELY 12:10 ON 2/26/2018, THE ONEOK PIPELINE CONTROL CENTER RECEIVED A CALL FROM A DCP EMPLOYEE AT THE DCP ANDREWS METER STATION CONNECTION, ADVISING OF VAPOR RELEASE ON ONEOK'S METER PIPING. THIS CONNECTION IS NOT ACTIVE AT THIS TIME. ONEOK FIELD EMPLOYEES RESPONDING TO THE CALL DETERMINED THE LEAK ORIGINATED BETWEEN TWO FLANGES WHERE A FLEXITALLIC GASKET AND A FIBER INSULATOR GASKET HAD BEEN IMPROPERLY INSTALLED TOGETHER. THE INSULATOR GASKET HAD FAILED AND WAS THE CAUSE OF THE LEAK. THE PIPING WAS ISOLATED AND DE-PRESSURED. THE FLEXITALLIC GASKET WAS REMOVED AND A NEW INSULATOR GASKET INSTALLED BETWEEN THE FLANGES AND RETURNED TO NORMAL OPERATIONS. ONEOK'S INVESTIGATION DETERMINED THE GASKETS HAD BEEN IMPROPERLY INSTALLED IN 2012 BY THE PREVIOUS OPERATOR OF THE ASSET."
