Incident Narrative
"AT APPROXIMATELY 11:17 ON 8/10/2018 THE ONEOK PANTHER CREEK PLANT OPERATOR NOTIFIED THE LOCAL PIPELINE OPERATOR OF A LEAK ON THE LIQUIDS PIPELINE METER SKID. THE SOURCE OF THE LEAK WAS IDENTIFIED TO BE THE YZ SAMPLE PUMP ON THE METER SKID. THE SAMPLE PUMP WAS REPLACED AND THE METER SKID WAS RETURNED TO SERVICE. UPON INVESTIGATION, IT WAS DETERMINED THAT A POSSIBLE CAUSE WAS VIBRATION FROM THE CUSTOMER'S PLANT PD PUMPS. THE CUSTOMER EVALUATED THE TWO PUMPS AND REPLACED THE DISCHARGE PULSATION STABILIZER BLADDERS ON BOTH OF THEM. IN ADDITION, THE CUSTOMER HAS SETUP A PREVENTATIVE MAINTENANCE PROGRAM TO EVALUATE THE PULSATION STABILIZERS QUARTERLY. A VIBRATION SWITCH HAS ALSO BEEN INSTALLED ON THE ONEOK NGL METER SKID AS AN ALARM TO NOTIFY THE ONEOK NGL PIPELINE CONTROL CENTER."
