The ANDOC design can be considered as the British construction industry's attempt to compete with Norway in this sector. McAlpine constructed three concrete platforms for the North Sea oil industry at Ardyne Point. The ANDOC type is very similar to the Sea Tank design, but the four concrete legs terminate and steel legs take over to support the ...
A tension-leg platform (TLP) or extended tension leg platform (ETLP) is a vertically moored floating structure normally used for the offshore production of oil or gas, and is particularly suited for water depths greater than 300 metres (about 1000 ft) and less than 1500 metres (about 4900 ft).

Platforms offshore Mexico. Offshore geotechnical engineering is a sub-field of geotechnical engineering. It is concerned with foundation design, construction, maintenance and decommissioning for human-made structures in the sea. [1] Oil platforms, artificial islands and submarine pipelines are examples of such structures. The seabed has to be ...
A fixed platform base under construction on a Louisiana river. A fixed platform is a type of offshore platform used for the extraction of petroleum or gas. These platforms are built on concrete and/or steel legs directly planted onto the seabed, supporting a deck with space for drilling rigs, production facilities and crew quarters. [1]
The Troll A platform is the tallest Condeep to date. [7] It was built over a period of four years, using a workforce of 2,000, and deployed in 1995 to produce gas from the enormous Troll oil field . With a total height of 472 metres (1,549 ft), Troll A was the tallest object that has ever been moved to another position, relative to the surface ...
