Incident Narrative
"ON MAY 13TH AT APPROXIMATELY 3:50 PM, AT THE ONEOK LUFKIN PUMP STATION, A SEAL FAIL WAS IDENTIFIED ON THE OB SEAL OF PUMP #2. THE OPERATOR ISOLATED AND FLARED DOWN THE PUMP AND MADE ALL INTERNAL NOTIFICATIONS AS REQUIRED. THE SEAL AND RELATED COMPONENTS WERE REPLACED AND THE PUMP WAS PLACED BACK IN SERVICE. THE FAILED SEAL WAS SENT TO THE MANUFACTURER FOR FAILURE ANALYSIS WHICH REVEALED THE FAILURE OF THE SEAL WAS CAUSED BY THE EXCESSIVE AMOUNT OF AXIAL THRUST, WHICH WAS DUE TO THE THRUST BEARING RETAINER ANTI-ROTATION TAB BEING WORN DOWN. THIS SPINNING OF THE THRUST BEARING'S OUTER RACE ALLOWED THE THRUST END PLATE TO WEAR RAPIDLY UNTIL THE OVERALL THRUST OF THE PUMP CAUSED THE FAILURE."
