Accident Classified As: Reportable Quantity
Cause of Problem: Seal or Gasket
The seal on a diesel circulation pump on VPS-2 (a crude distillation unit) failed as a reslut of a suspected bearing problem. This seal failure caused the release of approximately 434 bbls of untreated (sour) diesel, which ignited, resulting in a fire.
Discharge Preventable - No
An unanticipated pump seal failure caused this incident. Motiva regularly monitors, inspects, and conducts preventive maintenance on pumps. Despite the significant efforts, pump seal failures can still occasionally occur.
Notes/Remedial Actions
Motiva has slowed down production throughout the refinery until investigations are complete. Inspected, repaired, and rebuilt the pump as necessary. W/r/t pump seal failure, rotating equipmt and other personnel will complete the investigation and implement necessary changes to monitoring, inspection, and maintenance procedures
