Summary
Investigation of an approximately one-gallon condensate discharge from West Delta 41 A Platform into the Gulf of Mexico. A failed blanket-gas pressure regulator caused vessel overpressure and safety-valve relief. The vent discharged trapped rainwater and residual oil; debris obstructing the vent-boom drain allowed fluid to enter the sea.
