Summary
An investigation of a reported one-barrel oil spill during offshore platform restart identifies discharge from a relief scrubber before closed drain sump pumps were reset. Hydrostatic pressure forced oil through the sump vent. Findings discuss unfamiliarity with restart protocols, unchanged logic following pump replacement, and subsequent vent and safety-system modifications.
