Betelgeuse Incident - The Incident

The Incident

On 24 November 1978, the Betelgeuse left Ras Tanura in the Persian Gulf bound for Leixoes, Portugal with a full cargo of crude oil. Built in 1968 by Chantiers de l'Atlantique in Saint-Nazaire, France, the 121,432 DWT vessel was registered by Total S.A. at Le Havre, France.

Originally the Betelgeuse was to call at Sines, Portugal, to lighten the load of the ship, but poor weather conditions prevented the vessel from entering the harbour. Plans were further frustrated at Leixoes, where a ship had run aground across the harbour entrance, preventing the Betelgeuse from berthing there to discharge her cargo. The Betelgeuse was then instructed to sail for Whiddy Island, Ireland.

The Betelgeuse first put in at Vigo, Spain to change some of her crew, and then sailed for Whiddy Island on 30 December 1978. During the passage the vessel encountered heavy weather in the Bay of Biscay and after reporting a leakage of oil was instructed to head towards Brest, France at reduced speed. However, the origin of the leak was discovered and stopped. The vessel proceeded on its original planned course, arriving in Bantry Bay on 4 January 1979.

By 8 p.m. on 6 January 1979, the Betelgeuse had completed berthing at the offshore jetty in around 30 metres (98 ft) of water. At 11:30 p.m. the same day, the vessel commenced discharging its 114,000 tonnes of mixed Arabian crude oil, which was expected to take about 36 hours. A number of the crew went ashore while this was in progress and the wife of one of the officers joined her husband on the vessel.

At about 1:00 a.m. (evidence on the precise time conflicts) on Monday, 8 January, a rumbling or cracking noise was heard from the vessel, followed shortly by a huge explosion within its hull. The force of the explosion was seen to blow men from the jetty into the sea. Local residents reported seeing the Betelgeuse engulfed in a ball of fire a few moments later. A series of further explosions followed, breaking the vessel in half. Much of the oil cargo still on board ignited and this generated temperatures estimated to exceed 1,000 °C. The concrete unloading jetty crumbled and firefighters, arriving on the scene from several neighbouring towns, were unable to get near the vessel. The firefighters concentrated their efforts on preventing the fire from spreading to the tanks of the storage farm and on containing the oil spillage. Local families living on the island fled for their lives.

About 12 hours after the explosion the Betelgeuse sank at her moorings in 40 metres (130 ft) of water (with her stern becoming completely submerged), which largely extinguished the main body of the fire. In spite of this, rescue workers were not able to approach the wreck (the bows of which was still above water) for two weeks due to clouds of toxic and inflammable gas surrounding it. After two weeks, it was possible to start recovering bodies from the wreck and pumping off the remainder of the oil cargo that was still on board.
