The Betelgeuse incident, also known as the Betelgeuse or Whiddy Island disaster, occurred on 8 January 1979, at around 1 a.m., when the oil tanker Betelgeuse exploded in Ireland at the offshore jetty of the Whiddy Island Oil Terminal due to the failure of the ship's structure during an operation to discharge its cargo of oil. The tanker was owned by Total S.A. and the oil terminal was owned and operated by Gulf Oil.
The explosion and resulting fire claimed the lives of 50 people (42 French nationals, 7 Irish nationals and 1 English national). Only 27 bodies were recovered. A further fatality occurred during the salvage operation with the loss of a Dutch diver.
