The collision caused a release of liquefied petroleum gas, which entered the air intake for the main propulsion engines andignited. The Shanon E. Settoon was destroyed by the fire; the tank barge had limited fire damage and did not release any of the 93,000 gallons of crude oil it was carrying. The four crewmembers on board the Shanon E. Settoon escaped from the vessel, but one of them sustained second-and third-degree burns from which he died 1 month later.
