Witness

In 1980, 123 men were killed when the Alexander L. Kielland platform capsized in the North Sea oil fields.It was Norway's biggest industrial disaster and led to a range of safety improvements for those working in the country’s oil and gas sector. Lars Bevanger speaks to survivor Harry Vike, who spent 10 hours in a lifeboat waiting to be rescued, and his wife Grete, who was waiting for a call to find out if he was alive or dead.(Photo: The broken leg of the Alexander Kielland oil drilling platform, 1980.
