Date May 1991
Location: Off the coast of Angola The oil tanker ABT Summer, headed for Holland, was full to the brim when an explosion on board caused the ship to catch fire about 1 450 kilometres off the coast of Angola. Due to the explosion, the ship began leaking its oil into the ocean. The leak created a 128 square kilometre oil slick as the tanker burned for three days before sinking. The whole cargo of 80 million gallons of oil was lost to the sea, but thankfully the majority of the spill is believed to have been broken up by rough seas and caused little environmental damage, thanks to the offshore location of the event.
