The Lun-A (Lunskoye-A) platform, located off the north eastern coast of Sakhalin Island and is a concrete gravity base substructure (CGBS).. An oil platform (also called an oil rig, offshore platform, oil production platform, etc.) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed.
Offshore drilling 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.
Offshore drilling. Holstein, an oil drilling platform at Green Canyon in the Gulf of Mexico, approximately 100 miles from land. Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum that lies in rock formations beneath the ...
Spar (platform) A spar is a marine structure, used for floating oil/gas platforms. Named after navigation channel Spar buoys, spar platforms were developed as an extreme deepwater alternative to conventional platforms. [1] The deep draft design of spars makes them less affected by wind, wave, and currents and allows for both dry tree and subsea ...
Bullwinkle was a 1,736 feet (529 m) [1] tall, pile-supported fixed steel oil platform in the Gulf of Mexico. Installed in 1988, the total weight of the platform was 77,000 tons, of which the steel jacket comprises 49,375 tons. [2] At the time of its construction it was the third tallest freestanding structure ever built – shorter than only ...
Semi-submersible platform. A semi-submersible platform is a specialised marine vessel used in offshore roles including as offshore drilling rigs, safety vessels, oil production platforms, and heavy lift cranes. They have good ship stability and seakeeping, better than drillships. [1]
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). Use of tension-leg platforms has also been proposed ...
Petronius (oil platform) Coordinates: 29°06′30″N 87°56′30″W. Petronius is a deepwater compliant tower oil platform built from 1997 to 2000 [1] and operated by Chevron in the Gulf of Mexico, 210 km (130.5 mi) southeast of New Orleans, United States. A compliant piled tower design, it is 640 metres (2,100 ft) high [1] to the tip of ...
