The Boonwipa Rescue Volunteer unit reported the explosion of tanker Ampar 8 at 1.50pm while the ship was sailing past Phra Chulachomklao Fort of the Royal Thai Navy on its way to Bangkok.
The explosion was followed by a huge fire and billowing smoke at the front section of the ship. One crew member was killed and another injured, the volunteer unit said. Fourteen others were rescued.
