Summary
This alert describes an offshore production spill involving diverted flare-header flow and a failed rupture disc. More than 35 barrels of oil entered the ocean, mostly recovered. Alarm failures and continued pump operation worsened the incident. Recommendations address change management, rupture-disc inspection, alarm reliability and training; the initial process-upset cause remained undetermined.
