In 2001, an explosion destabilised the P36 production rig in the Campos Basin, Brazil, eventually causing it to sink.Ī design error resulted in the structural failure in 1991 of the gravity base unit of the original Sleipner A platform.Update 3:00 p.m. In 1980, a Wilson Brothers rig on Lake Peigneur drilled into a salt mine, leading to the flooding and eventual collapse of the mine.Ī ballast control malfunction caused the Ocean Ranger to capsize during a ferocious storm in the North Atlantic in 1982, with the loss of all hands. The Rowan Gorilla I was crossing the North Atlantic in 1988 when it capsized and sank after structural failure caused by bad weather.Ī storm in 1990 caused structural failure and flooding to the West Gamma, resulting in its sinking after towline loss. Mr Bice sank in 1998 in the Gulf of Mexico after structural failure and flooding. The Ocean Master II sank off West Africa in 1977 as a result of structural problems and bad weather. The Key Biscayne capsized and sank off Australia's west coast in 1983 after flooding and towline failure.Īnother casualty of towline failure, the Ocean Express sank in 1976 during a storm in Gulf of Mexico. In 1979, the jack-up Bohai 2 capsized and sank in a storm while on tow off the coast of China.Īfter a dramatic crew rescue in 1989, the Interocean II sank in a North Sea storm after towline failure. One of the first drilling rigs in the North Sea, the Sea Gem collapsed in 1965 as a result of metal fatigue.Ī rare self-elevating semi-submersible, the Transocean III capsized and sank East of Orkney after a jackable leg broke away in 1974.

The UK-built semi-sub Ocean Prince, finder of the first UK offshore oil, broke up off England's east coast during a storm in 1967.įailure of the jacking mechanism caused the Parker rig to collapse in 2003.Īfter being jacked up on location in 1979, the rig Ranger I collapsed due to fatigue in the stern leg. Whilst skidding the rig cantilever, the jack-up Al Mariyah collapsed and lost its derrick onto the platform below.Ī punch-through caused extensive damage to the Maersk Victory while working in Australian waters in 1996. Kielland capsized during a storm after a leg support brace failed. In 1980, the semi-submersible accommodation rig Alexander L. Material failure on oil platforms and the assoiated gear parts is unforging as huge ocean portions can be polluted and many animals killed.Ī few examples of collapsed platforms are : These subsea solutions may consist of one or more subsea wells, or of one or more manifold centres for multiple wells. Remote subsea wells may also be connected to a platform by flow In many cases, the platform contains facilities to house the workforce as well.ĭepending on the circumstances, the platform may be fixed to the ocean floor, may consist of an artificial island, or may float. Product until it can be brought to shore for refining and marketing. Oil platforms, offshore platforms, or more colloquially oil rigs are huge engineering structures for enabling to drill wells, to extract and process oil and natural gas, or to temporarily store
