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 oil well drilling platform, Continental Oil Co., Gulf of Mexico, 1955. Around 1891, the first submerged oil wells were drilled from platforms built on piles in the fresh waters of the Grand Lake St. Marys in Ohio. The wells were developed by small local companies such as Bryson, Riley Oil, German-American and Banker's Oil. [2]
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.
In early oil exploration, drilling rigs were semi-permanent in nature and the derricks were often built on site and left in place after the completion of the well. In more recent times drilling rigs are expensive custom-built machines that can be moved from well to well.
An oil rig is any kind of apparatus constructed for oil drilling. Kinds of oil rig include: Drilling rig, an apparatus for on-land oil drilling; Drillship, a floating apparatus for offshore oil drilling; Oil platform, an apparatus for offshore oil drilling; Oil well, a boring from which oil is extracted
Platform being towed out to sea. 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]
The base and the deck were built separately, and were joined in 1998 while the base was partially submerged. The base is a Condeep gravity base structure built from reinforced concrete. The Troll platform was towed over 200 kilometres (120 mi) from Vats, in the northern part of Rogaland, to the Troll field, 80 kilometres (50 mi) north-west of ...
Specialist floating hotel vessels known as flotels or accommodation rigs are used to accommodate workers during the construction and hook-up phases. This is a high cost activity due to the limited space and access to materials. [clarification needed] Oil platforms are key fixed installations from which drilling and production activity is ...
