The incident

On the morning of 28 May 1991, the Liberian oil tanker ABT Summer exploded 1,287 km off the coast of Angola (Africa). It was transporting 260,000 tonnes of heavy Iranian crude. In the afternoon, 7 vessels arrived onsite to rescue the crew. 27 people were rescued, however one person was killed and 4 went missing.

Two tugs, the Red Kestrel and the Red Robin, as well as a plane attempted to fight the fire onboard the ship.

On 29 May, the flames were still raging onboard the ABT Summer and an oil slick was beginning to form around the ship (32 km long by 7 km wide). The tanker burnt for 3 days before sinking on 1st June.

In June, the response team attempted to track down signs from the ABT Summer to locate the wreck, in vain. The wreck has never been found since.

Impact

As the incident occurred far from the coast, there was little environmental impact.
