Condeep
Condeep is a make of gravity-based structure for oil platforms invented and patented by engineer Olav Mo in 1972, which were fabricated by Norwegian Contractors in Stavanger, Norway.Fagerberg; Mowery; Verspagen, p.192 ''Condeep'' is an abbreviation for ''concrete deep water structure''. A Condeep usually consists of a base of concrete oil storage tanks from which one, three or four concrete shafts rise. The Condeep base always rests on the sea floor, and the shafts rise to about 30 meters above the sea level. The platform deck itself is not a part of the construction. The Condeep is used for a series of production platforms introduced for crude oil and natural gas production in the North Sea and Norwegian continental shelf. Following the success of the concrete oil storage tank on the Ekofisk field, Norwegian Contractors introduced the Condeep production platform concept in 1973. This gravity-based structure for a platform was unique in that it was built from reinforced conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brent Oil Field
The Brent field was an oil and gas field located in the East Shetland Basin of the North Sea, north-east of Lerwick in the Shetland Islands, Scotland, at the water depth of . The field operated by Shell UK Limited was discovered in 1971 and was once one of the most productive parts of the UK's offshore assets but has reached the stage where production is no longer economically viable. Decommissioning of the Brent field is complete with the exception of Brent C, which is producing from another field. The discovery well 211/26-1 was drilled in 1971 by the semi-submersible drilling rig "Staflo". This was a major surprise at the time as the nearest land in Scotland and Norway is composed of granite and other non reservoir metamorphic rocks. Name Shell initially named all of its UK oil fields after seabirds in alphabetical order by discovery – Auk, Brent, Cormorant, Dunlin, Eider, Fulmar and so on. Brent refers to the brent goose, and in turn gave its initials to the geologic s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stavanger
Stavanger (, , American English, US usually , ) is a city and municipalities of Norway, municipality in Norway. It is the fourth largest city and third largest metropolitan area in Norway (through conurbation with neighboring Sandnes) and the administrative center of Rogaland county. The municipality is the fourth most populous in Norway. Located on the Stavanger Peninsula in southwest Norway, Stavanger counts its official founding year as 1125, the year the Stavanger Cathedral was completed. Stavanger's core is to a large degree 18th- and 19th-century wooden houses that are protected and considered part of the city's cultural heritage. This has caused the town center and inner city to retain a small-town character with an unusually high ratio of detached houses, and has contributed significantly to spreading the city's population growth to outlying parts of Greater Stavanger. The city's population rapidly grew in the late 20th century due to its oil industry. Stavanger is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beryl Oil Field
The Beryl oil field is a major crude oil production field in the UK sector of the northern North Sea, 335 km north east of Aberdeen. Production of oil started in 1976 and the field is still producing oil and gas (2021). The field The Beryl oil field is located in Block 9/13a of the UK North Sea. It is named after Beryl Solomon wife of Charles Solomon the President of Mobil Europe at the time of the field’s discovery. The Beryl field was discovered in May 1972 and is a Triassic and Jurassic sandstone at an average depth of 11,000 feet (3,353 m). The reservoir and the fluids have the following characteristics: Owners and operators The Beryl field was originally licensed to partners comprising Mobil North Sea Ltd (50%), Amerada Hess (UK) Ltd (20%), Texas Eastern North Sea Inc. (20%), and Enterprise Oil Ltd. (10%). Mobil was the Beryl field operator. In January 2012 the Apache Corporation acquired all the assets of Mobil North Sea and from then was the operator of the Beryl f ...

Oil Platform
An oil platform (or oil rig, offshore platform, oil production platform, and similar terms) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed. Many oil platforms will also have facilities to accommodate the workers, although it is also common to have a separate accommodation platform bridge linked to the production platform. Most commonly, oil platforms engage in activities on the continental shelf, though they can also be used in lakes, inshore waters, and inland seas. Depending on the circumstances, the platform may be fixed Platform, fixed to the ocean floor, consist of an artificial island, or floating oil production system, float. In some arrangements the main facility may have storage facilities for the processed oil. Remote subsea wells may also be connected to a platform by flow lines and by umbilical cable, umbilical connections. These sub-sea facilities may include of one or more subsea ...

Sleipner A Offshore Platform
Sleipner A is a combined accommodations, production and processing offshore platform at the Sleipner East gas field in the Norwegian sector of the North Sea. It is a Condeep-type oil platform, built in Norway by the company Norwegian Contractors for Equinor. It is known for its catastrophic failure on 23 August 1991, due to a design flaw, that resulted from an error caused by unconservative concrete codes and inaccurate finite element analysis modelling of the tricell, which formed part of the ballasting/flotation system. Location Sleipner A is located on the Sleipner East gas field on the North Sea. Also six satellite fields–Gungne, Loke, Alpha North, Sigyn, Volve and Volve South–are tied-back to Sleipner A. In addition to its own operations, the platform is used as a remote operation center for the Sleipner B wellhead platform. The Sleipner B is operated from the Sleipner A via an umbilical cable. In addition, the Sleipner T carbon dioxide treatment platform is linked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troll Oil Field
Troll is a natural gas and oil field in the Norwegian sector of the North Sea, one of the biggest in the North Sea, holding 40% of Norway’s gas – it also possesses significant quantities of oil, in thin zones under the gas cap, to the west of the field.

Gravity-based Structure
A gravity-based structure (GBS) is a support structure held in place by gravity, most notably offshore oil platforms. These structures are often constructed in fjords due to their protected area and sufficient depth. Offshore oil platforms Prior to deployment, a study of the seabed must be done to ensure it can withstand the vertical load from the structure.Dean, E.T.R. (2010). Offshore Geotechnical Engineering - Principles and Practice. Thomas Telford, Reston, VA, U.S.A., 520 p. It is then constructed with steel reinforced concrete into tanks or cells, some of which are used to control the buoyancy. When construction is complete, the structure is towed to its intended location. Wind turbines Early deployments of offshore wind power turbines used these structures. As of 2010, 14 of the world's offshore wind farms had some of their turbines supported by gravity-based structures. The deepest registered offshore wind farm with gravity-based structures is Thornton Bank 1, Belgi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Platform Norway
An oil is any polarity (chemistry), nonpolar chemical substance that is composed primarily of Hydrocarbon, hydrocarbons and is hydrophobe, hydrophobic (does not mix with water) & lipophilicity, lipophilic (mixes with other oils). Oils are usually flammable and surfactant, surface active. Most oils are unsaturated lipids that are liquid at room temperature. The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal fats, animal, vegetable oil, vegetable, or petrochemical in origin, and may be Volatility (chemistry), volatile or non-volatile. They are used for food (e.g., olive oil), fuel (e.g., heating oil), medical purposes (e.g., mineral oil), lubrication (e.g. motor oil), and the manufacture of many types of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies and rituals as purifying agents. Etymology First attested in English 1 ...
