Accident Classified As: Reportable Quantity
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.
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.
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
