Accident Classified As: Below Reportable Quantity (BRQ)
Cause of Problem: Piping or Tubing
The emission point involved was a pinhole leak on the pump casing of 222-1501-02. Sour LPG leaked to the atmosphere causing the unit fixed monitor 222-AI-0019 to go in and out of alarm. Operators donned SCBA's to investigate and discovered a leak in the weld for the seal flush piping at the pump casing of 222-1501-02. The 222-1505-02 Liguid Feed Pump was out of service, leaving no spare. Emergency Shutdown of Unit 222 Sats Gas Plant (SGP) was activated.
Discharge Preventable - Under Investigation
Notes/Remedial Actions
Unit 222 Sats Gas Plant was shutdown when the emergency shutdown EIV-1 was closed from a remote location by the Shift Emergency Response Team (SERT). The pump was kept on until all liquid could be diverted to Unit 222 (Sats Gas Plant). The pump was then isolated for maintenance. Once the investigation is complete, recommendations will be implemented.
