Corexit
Corexit (often styled COREXIT) is a product line of oil dispersants used during oil spill response operations. It is produced by Nalco Holding Company, an indirect subsidiary of Ecolab. Corexit was originally developed by the Standard Oil Company of New Jersey. Corexit is typically applied by aerial spraying or spraying from ships directly onto an oil slick. On contact with the dispersant, oil that would otherwise float on the surface of the water is emulsified into tiny droplets and sinks or (in the unusual case of sub-surface application) remains suspended in the water. In theory this allows the oil to be more rapidly degraded by bacteria (bioremediation) and prevents it from accumulating on beaches and in marshes. Corexit was used in unprecedented quantities during the 2010 Deepwater Horizon oil spill in the Gulf of Mexico and became the largest use of such chemicals in the United States. In addition to spraying the dispersant onto the surface slick, it was used in an unteste ... [...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 ...

Oil Dispersants
An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill. Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water. Dispersant use involves a trade-off between exposing coastal life to surface oil and exposing aquatic life to dispersed oil. While submerging the oil with dispersant may lessen exposure to marine life on the surface, it increases exposure for animals dwelling underwater, who may be harmed by toxicity of both dispersed oil and dispersant. Although dispersant reduces the amount of oil that lands ashore, it may allow faster, deeper penetration of oil into coastal terrain, where it is not easily biodegraded. History ''Torrey Canyon'' In 1967, the supertanker ''Torrey Canyon'' leaked oil onto the English coastline. Alkylphenol surfactants were primarily used to break up the oil, but proved very toxic in the marine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Bonython Oil Spill
The Port Bonython oil spill occurred on 30 August 1992, when the fuel tank of the tanker ''Era'' was pierced by the bow of the tugboat ''Turmoil'' during berthing operations in upper Spencer Gulf, South Australia.AMSA: Australian Maritime Safety Authority > Era''Australian Maritime Safety Authority'', Government of Australia, Australia. Accessed 2014-02-07. Wind and swell were high and 296 tonnes of bunker fuel were released into Spencer Gulf. The incident resulted in 500 oiled birds and damage to 15 km of mangrove and seagrass habitat south-west of Port Pirie. Spill 30 August The spill occurred at 10.52am, as the ''Era ''was berthing at the Port Bonython wharf in rough seas. The vessel had arrived to load oil for the Kwinana refinery. The ''Era'' was chartered by BP and the tugboat involved, ''Turmoil'', was property of the Adelaide Steamship Company.Pearce, Wade "Chemicals attacking 2km slick - Oil spill threat to Gulf animals" ''The Advertiser'', South Australia (1 ...

Montara Oil Spill
The Montara oil spill was an oil and gas leak and subsequent slick that took place in the Montara oil field in the Timor Sea, off the northern coast of Western Australia. It is considered one of Australia's worst oil disasters. The slick was released following a blowout from the Montara wellhead platform on 21 August 2009, and continued leaking until 3 November 2009 (in total 75 days), when the leak was stopped by pumping mud into the well and the wellbore cemented thus "capping" the blowout. The West Atlas rig is owned by the Norwegian-Bermudan Seadrill, and operated by PTTEP Australasia (PTTEPAA), a subsidiary of PTT Exploration and Production (PTTEP) which is in turn a subsidiary of PTT, the Thai state-owned oil and gas company was operating over on adjacent well on the Montara platform. Houston-based Halliburton was involved in cementing the well. The Montara field is located off the Kimberley coast, north of Truscott airbase, and west of Darwin. Sixty-nine workers we ...

Exxon Valdez Oil Spill
The ''Exxon Valdez'' oil spill occurred in Prince William Sound, Alaska, on March 24, 1989. '' Exxon Valdez'', an oil supertanker owned by Exxon Shipping Company bound for Long Beach, California struck Prince William Sound's Bligh Reef, west of Tatitlek, Alaska at 12:04 a.m. and spilled (or 37,000 tonnes) of crude oil over the next few days. The ''Exxon Valdez'' spill is the second largest in U.S. waters, after the 2010 ''Deepwater Horizon'' oil spill, in terms of volume of oil released. Prince William Sound's remote location, accessible only by helicopter, plane, or boat, made government and industry response efforts difficult and made existing response plans especially hard to implement. The region is a habitat for salmon, sea otters, seals, and seabirds. The oil, extracted from the Prudhoe Bay Oil Field, eventually affected of coastline, of which were heavily or moderately oiled.

Oil Spill
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land. Oil spills may be due to releases of crude oil from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined petroleum products (such as gasoline, diesel) and their by-products, heavier fuels used by large ships such as bunker fuel, or the spill of any oily refuse or waste oil. Oil spills penetrate into the structure of the plumage of birds and the fur of mammals, reducing its insulating ability, and making them more vulnerable to temperature fluctuations and much less buoyant in the water. Cleanup and recovery from an oil spill is difficult and depends upon many factors, including the type of oil spilled, the temperature of the water (affec ...

SS Arrow
The SS ''Arrow'' was an oil tanker built by Bethlehem Steel Company, Sparrows Point, Baltimore, Maryland in 1948 as the tanker ''Olympic Games''. Renamed ''Sea Robin'' in 1960 and finally ''Arrow'' in 1962, the ship was a Liberian-registered tanker owned by the Sun Navigation Company. At 551.2 feet (167.9 metres) in length and 68.3 feet (20.7 metres) in width, with a draft of 29.9 feet (9.1 metres), she was an enlarged version of the standard American World War II tanker design and one of the oldest tankers in the fleet of Aristotle Onassis. The ''Arrow'' ran aground and spilled its load of oil into Chedabucto Bay on February 4, 1970. This remains the most significant oil spill off Canada’s East Coast, with some 10,000 tonnes (about 25% of the amount spilled by the Exxon Valdez in Alaska in 1989). Only the MV ''Kurdistan'' accident has come close, spilling about 6,000 tons of oil after breaking apart in the Cabot Strait on March 15, 1979. Accident and loss ''Arrow'' took on app ...
