Dunlin Oilfield
The Dunlin oilfield is situated 195 km northeast of Lerwick, Shetland, Scotland, in block number 211/23a and 211/24a. It was originally operated by Royal Dutch Shell, Shell but was sold in 2008 and is now operated by Fairfield Energy and partners MCX. Under Fairfield initially the platform was operated using the duty holder model. Amec (now Worley) were the duty holder contractor and Aker Solutions was the engineering and upgrade project contract. Fairfield became the duty holder in April 2014. The Field was originally discovered in July 1973 in a water depth of 151 metres (495 ft) approximately 12 km from the UK-Norway median line. Estimated recovery is 363 million barrels of oil. The oil reservoir is located at a depth of 9,000 feet (2,740 metres). Dunlin acts as the host platform for production from the Osprey and Merlin subsea fields.

Lerwick
Lerwick (; non, Leirvik; nrn, Larvik) is the main town and port of the Shetland archipelago, Scotland. Shetland's only burgh, Lerwick had a population of about 7,000 residents in 2010. Centred off the north coast of the Scottish mainland and on the east coast of the Shetland Mainland, Lerwick lies north-by-northeast of Aberdeen; west of the similarly sheltered port of Bergen in Norway; and south east of Tórshavn in the Faroe Islands. One of the UK's coastal weather stations is situated there, with the local climate having small seasonal variation due to the maritime influence. Being located further north than Saint Petersburg and the three mainland Nordic capitals, Lerwick's nights in the middle of summer only get dark twilight and winters have below six hours of complete daylight. History Lerwick is a name with roots in Old Norse and its local descendant, Norn, which was spoken in Shetland until the mid-19th century. The name "Lerwick" means ''bay of clay''. The c ...

North Sea Oil Fields
North Sea oil is a mixture of hydrocarbons, comprising liquid petroleum and natural gas, produced from petroleum reservoirs beneath the North Sea. In the petroleum industry, the term "North Sea" often includes areas such as the Norwegian Sea and the area known as "West of Shetland", "the Atlantic Frontier" or "the Atlantic Margin" that is not geographically part of the North Sea. Brent crude is still used today as a standard benchmark for pricing oil, although the contract now refers to a blend of oils from fields in the northern North Sea. From the 1960s to 2014 it was reported that 42 billion barrels of oil equivalent (BOE) had been extracted from the North Sea since when production began, and there is still a potential of 24 billion BOE left remaining there, which is equivalent to about 35 years worth of production, the North Sea will remain as an important petroleum reservoir for years to come. History 1851–1963 Commercial extraction of oil on the shores of the North Sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Flare
A gas flare, alternatively known as a flare stack, flare boom, ground flare, or flare pit is a gas combustion device used in places such as petroleum refineries, chemical plants and natural gas processing plants, oil or gas extraction sites having oil wells, gas wells, offshore oil and gas rigs and landfills. In industrial plants, flare stacks are primarily used for burning off flammable gas released by safety valves during unplanned over-pressuring of plant equipment. (See Chapter 11, ''Flare Stack Plume Rise''). During plant or partial plant startups and shutdowns, they are also often used for the planned combustion of gases over relatively short periods. At oil and gas extraction sites, gas flares are similarly used for a variety of startup, maintenance, testing, safety, and emergency purposes. In a practice known as production flaring, they may also be used to dispose of large amounts of unwanted associated petroleum gas, possibly throughout the life of an oil well. 5 ...

Electrical Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external electrical circuit, circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand crank (mechanism), cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sullom Voe
Sullom Voe is an inlet of the North Sea between the parishes of Delting and Northmavine in Shetland, Scotland. It is a location of the Sullom Voe oil terminal and Shetland Gas Plant. The word Voe is from the Old Norse ' and denotes a small bay or narrow creek. The head of the voe makes up the eastern side of Mavis Grind. The Voe, the longest in Shetland, and partially sheltered by the island of Yell was used as a military airfield during World War II both by the Royal Air Force and the Royal Norwegian Air Force as a location for flying boats. With the coming of the oil terminal, the remains of the airfield were upgraded and modernised to create Scatsta Airport which was primarily used to service the terminal. The first crude oil was discovered in the North Sea in 1969, and soon thereafter construction began on the oil terminal at Sullom Voe, north east of the village of Brae, which became operational in 1975 and was completed in 1982, becoming the largest in Europe.

Shetland
Shetland, also called the Shetland Islands and formerly Zetland, is a subarctic archipelago in Scotland lying between Orkney, the Faroe Islands and Norway. It is the northernmost region of the United Kingdom. The islands lie about to the northeast of Orkney, from mainland Scotland and west of Norway. They form part of the border between the Atlantic Ocean to the west and the North Sea to the east. Their total area is ,Shetland Islands Council (2012) p. 4 and the population totalled 22,920 in 2019. The islands comprise the Shetland constituency of the Scottish Parliament. The local authority, the Shetland Islands Council, is one of the 32 council areas of Scotland. The islands' administrative centre and only burgh is Lerwick, which has been the capital of Shetland since 1708, before which time the capital was Scalloway. The archipelago has an oceanic climate, complex geology, rugged coastline, and many low, rolling hills. The largest island, known as " the Mainland", ...

Offshore Concrete Structure
Offshore concrete structures have been in use successfully for about 50 years. They serve the same purpose as their steel counterparts in the oil and gas production and storage. The first concrete oil platform has been installed in the North Sea in the Ekofisk field in 1973 by Phillips Petroleum. Since then 47 major concrete offshore structures have been built. Introduction Concrete offshore structures are mostly used in the petroleum industry as drilling, extraction or storage units for crude oil or natural gas. Those large structures house machinery and equipment needed to drill and/or extract oil and gas. But concrete structures are not only limited to applications within the oil and gas industry. Several conceptual studies have shown recently, that concrete support structures for offshore wind turbines are very competitive compared to common steel structures, especially for larger water depths. Depending on the circumstances, platforms may be attached to the ocean floor, cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
