Containment Dome
A containment dome is a component of the system designed to contain the underwater blowout of an oil well such as occurred with the Macondo Well blowout from the Deepwater Horizon oil spill. This portion of the system is designed as a vacuum to suck up the products being expelled from a blowout and deliver those products to the containment system housed on the vessel moored above the blowout. Superior Energy Services is constructing this device to be used by Shell Oil Company on the barge '' Arctic Challenger'' as their "fourth line of defense" against a blowout in the Arctic drilling regions in the Chukchi Sea and Beaufort Sea The Beaufort Sea (; french: Mer de Beaufort, Iñupiaq: ''Taġiuq'') is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, the Yukon, and Alaska, and west of Canada's Arctic islands. The sea is named after Sir Fr .... The fourth method, which was constructed in Bellingham, Washington, US is the containment barge carryin ...

Arctic Challenger
''Arctic Challenger'' is a barge which has been converted by Superior Energy Services for use in the Arctic drilling operations of Shell Oil Company. This barge is designed to function as a "novel engineering solution" which they refer to as an Arctic Containment System to respond should a blowout event occur at drilling sites in the Beaufort or Chukchi Seas. According to testimony provided to Senator Mark Begich on 11 October 2012, Coast Guard Rear Admiral Thomas Ostebo said the certification for the Shell spill barge Arctic Challenger to operate in Alaska was given on the 10th of October at the Bellingham, Washington shipyard where it was constructed. Ostebo is commander of the Coast Guard's 17th district, which covers Alaska. The US Bureau of Safety and Environmental Enforcement (BSEE) reported that the vessel was able to meet their requirement for processing 2000 gallons of seawater per minute during testing in March, 2013. Greenberry Industrial has been contracted to provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Containment Dome For Arctic Challenger
Containment was a geopolitical strategic foreign policy pursued by the United States during the Cold War to prevent the spread of communism after the end of World War II. The name was loosely related to the term ''cordon sanitaire'', which was containment of the Soviet Union in the interwar period. As a component of the Cold War, this policy caused a response from the Soviet Union to increase communist influence in Eastern Europe, Asia, Africa, and Latin America. Containment represented a middle-ground position between détente (relaxation of relations) and rollback (actively replacing a regime). The basis of the doctrine was articulated in a 1946 cable by US diplomat George F. Kennan during the post-World War II term of US President Harry S. Truman. As a description of US foreign policy, the word originated in a report Kennan submitted to US Defense Secretary James Forrestal in 1947, which was later used in a magazine article. Earlier uses of term There were major historica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blowout (well Drilling)
A blowout is the uncontrolled release of crude oil and/or natural gas from an oil well or gas well after pressure control systems have failed.'All About Blowout', R. Westergaard, Norwegian Oil Review, 1987 Modern wells have blowout preventers intended to prevent such an occurrence. An accidental spark during a blowout can lead to a catastrophic oil or gas fire. Prior to the advent of pressure control equipment in the 1920s, the uncontrolled release of oil and gas from a well while drilling was common and was known as an oil gusher, gusher or wild well. History Gushers were an icon of oil exploration during the late 19th and early 20th centuries. During that era, the simple drilling techniques, such as cable-tool drilling, and the lack of blowout preventers meant that drillers could not control high-pressure reservoirs. When these high-pressure zones were breached, the oil or natural gas would travel up the well at a high rate, forcing out the drill string and creating a gus ...

Macondo Prospect
The Macondo Prospect (Mississippi Canyon Block 252, abbreviated MC252) is an oil and gas prospect in the United States Exclusive Economic Zone of the Gulf of Mexico, off the coast of Louisiana. The prospect was the site of the ''Deepwater Horizon'' drilling rig explosion in April 2010 that led to a major oil spill in the region from the first exploration well, named itself MC252-1 (nicknamed also Macondo-1), which had been designed to investigate the existence of the prospect. Name Oil companies routinely assign code names to offshore prospects early in the exploration effort. This practice helps ensure secrecy during the confidential pre-sale phase, and later provides convenient names for casual reference rather than the often similar-sounding official lease names denoted by, for example, the Minerals Management Service in the case of federal waters in the USA. Names in a given year or area might follow a theme such as beverages (e.g., Cognac), heavenly bodies (e.g., Mars), or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deepwater Horizon Oil Spill
The ''Deepwater Horizon'' oil spill (also referred to as the "BP oil spill") was an industrial disaster that began on 20 April 2010 off of the coast of the United States in the Gulf of Mexico on the BP-operated Macondo Prospect, considered to be the largest marine oil spill in the history of the petroleum industry and estimated to be 8 to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf of Mexico. The United States federal government estimated the total discharge at . After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. Reports in early 2012 indicated that the well site was still leaking. The ''Deepwater Horizon'' oil spill is regarded as one of the largest environmental disasters in world history. A massive response ensued to protect beaches, wetlands and estuaries from the spreading oil utilizing skimmer ships, floating booms, controlled burns and of oil dispersant. Due to t ...

Chukchi Sea
Chukchi Sea ( rus, Чуко́тское мо́ре, r=Chukotskoye more, p=tɕʊˈkotskəjə ˈmorʲɪ), sometimes referred to as the Chuuk Sea, Chukotsk Sea or the Sea of Chukotsk, is a marginal sea of the Arctic Ocean. It is bounded on the west by the Long Strait, off Wrangel Island, and in the east by Point Barrow, Alaska, beyond which lies the Beaufort Sea. The Bering Strait forms its southernmost limit and connects it to the Bering Sea and the Pacific Ocean. The principal port on the Chukchi Sea is Uelen in Russia. The International Date Line crosses the Chukchi Sea from northwest to southeast. It is displaced eastwards to avoid Wrangel Island as well as the Chukotka Autonomous Okrug on the Russian mainland. Geography The sea has an approximate area of and is only navigable about four months of the year. The main geological feature of the Chukchi Sea bottom is the Hope Basin, which is bound to the northeast by the Herald Arch. Depths less than occupy 56% of the total ...

Beaufort Sea
The Beaufort Sea (; french: Mer de Beaufort, Iñupiaq: ''Taġiuq'') is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, the Yukon, and Alaska, and west of Canada's Arctic islands. The sea is named after Sir Francis Beaufort, a hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea's shores. The sea, characterized by severe climate, is frozen over most of the year. Historically, only a narrow pass up to opened in August–September near its shores, but recently due to climate change in the Arctic the ice-free area in late summer has greatly enlarged. Until recently, the Beaufort Sea was known as an important reservoir for the replenishment of Arctic sea ice. Sea ice would often rotate for several years in the Beaufort Gyre, the dominant ocean current of the Beaufort Sea, growing into sturdy and thick multi-year i ...
