Accident Classified As:
Refinery letter states that Motiva experienced a flaring release caused by an unexpected shutdown of the Coker Wet Gas compressor due to power loss. Power loss is attributed to fault in MCC breaker and 4160V buss.
"Motiva has determined that this event is not preventable due to the design configuration and failure mechanism."
RQ. Coker Unit shutdown and restarted when flaring stopped. Re-evaluated relay settings and adjusted as needed to reduce potential for future trips.
