Summary
Torch cutting near oil storage tanks preceded an explosion without fire that ruptured two tanks and spilled an estimated 29 barrels of crude oil overboard. The investigation identified probable ignition of escaping vapours, aggravated by a corrosion-plugged flame arrestor. Recommendations address periodic inspection, accessible positioning and protection of tanks during hot work.
