Accident Classified As: No Information Given
RTO unit atmospheric safety and associated flaring caused by loss of an electronic card and computer failure. Failure of a computer control card resulted in several control valves to fail in the closed position and the atmospheric safety valve then lifted to the flare.
Non preventable released as failure of computer card could not be anticipated.
The card was replaced with a spare and the unit operations were reduced to minimize released.
