Early in the evening of 27 March 1980, more than 200 men were off duty in the accommodation on Alexander L. Kielland. Conditions were rainy with dense fog, with the wind gusting to 40 knots (74 km/h) and waves up t. .

Kielland was recovered in 1983 at the third attempt. The rig was scuttled later that year in the Fjord after a search for missing bodies had been completed, as well as several tests to determine the cause of the disas.

[pdf] This article lists the main components of a onshore . rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the items listed below.
