Accident Classified As: Below Reportable Quantity (BRQ)
On 3/4/2014, Shell Chemical's OP-1 Unit flared process gas at the GO1 Elevated Flare due to low lube oil pressure on the process gas compressor (PGC). The main lube oil pump for the PGC had a mechanical failure and unexpectedly shutdown, resulting in the shutdown of the PCG.
The mechanical failure of the PGC was sudden and unexpected.
Immediately, feed was safely removed from the OP-1 PGC and once the failure was identified, the feed was removed from the OP-1 furnace to repair the PGC. To prevent the recurrence of this incident, the failed mechanical components of the affected lube oil system of the PGC were repaired and the OP-1 Unit was safely restarted and returned to normal operation on 3/14/2014.
