Oil Drilling

Have you forever seen an animal covered in sludge, helpless and weak? offshore oil color bore is one of our introductions biggest concerns. seaward oil drilling is the discovery of finding oil or gasoline resources underwater. comm hardly the oil is found off the coasts of each continent and dismiss also be found in lakes and small seas. Drilling for oil provides the energy to make fuels for cars and other machinery. Many different weapons platforms can be used for offshore oil drilling such as drill ships, jack up barges, brand name jackets, and semi- submersibles for trencher water argonas.The issue at hand is that oil drilling can lead to oil twilights into oceans, seas, and lakes and can harm the purlieu. Barge collisions, explosions, leaks, spills, and pipeline corrosion ar all come across factors in the harmful effects of oil drilling. Drilling leads to pollution in the environment and kills many organisms and aquatic animals. Animals play a key role in society , especially the marine animals. Long term effects create damage to the f atomic number 18 chain, fisheries, health, the ecosystem balance, and enjoyment of nature.Oil spills harm the lives of marine life and the federal government allows them to be killed during gas and oil drilling. When explosives are used to remove the oil sets, pipelines can be demolished the oil go away spill everywhere. Aquatic life is endangered around these oil rigs and causes many hatchlings not to be brought into the world. Sea turtles are attracted to bright lights and if the oil rig has created an explosion, they will head toward that direction, endangering their own lives for vicious predators along the way.Not only is marine life affected, only if birds. Many types of birds are endangered as well like ducks, seagulls, and pelicans. If the ocean is polluted with toxic oil and they decide to swim in it, all the oil will loll stuck on their feathers not allowing them to fly. Oil drilling is dangerou s and can lead to the extinction of many animals. The linked States needs oil, but offshore drilling is not the way to get it. There are potbelly of other alternating(a)s we can use to create gasoline such an ethanol.Ethanol uses agricultural products to make an alternative gas product and it has proven to proven to be cost effective. The U. S. should also use hybrid cars and galvanizing vehicles instead of relying on oil. Forms of transportation should also be aware of the oil efficiency and should begin apply smart growth to make less pollution and reduce gridlock. Air pollution will be cut and the amount of oil used will be reduced for a better environment. Offshore oil drilling does provide puffy amounts of oil, but there should be a limit on how much should be consumed at one given time.Another key factor of oil drilling is the cost. President Barack Obama has come up with energy proposals to help the environment and cut the costs our nation has attribute on oil. In ord er to economise energy and taxpayer dollars, my administration is doubling the list of hybrid vehicles in the federal fleet, even as we seek to reduce the number of cars and trucks used by our government overall, Obama said. His plans are too drill along the Southern Atlantic coastlines and move away from Alaska, for it is too dangerous and uncollectible for the environment.Expanding drilling is definitely not the solution our country needs and therefore something needs to be done. Since the bolt down that is going to be drilled cannot provide a base for offshore drilling as it does for shoreward drilling, an artificial platform must be created. This artificial platform can take many forms, depending on the characteristics of the well to be drilled, including how far underwater the drilling target is. One of the most important pieces of equipment for offshore drilling is the subsea drilling template.Essentially, this piece of equipment connects the underwater well site to the d rilling platform on the break through of the water. This device, resembling a cookie cutter, consists of an open steel box with multiple holes in it, dependent on the number of wells to be drilled. This drilling template is placed over the well site, and usually lowered into the use up position required using satellite and GPS technology. A relatively school hole is then dug, in which the drilling template is cemented into place.The drilling template, secured to the sea floor and attached to the drilling platform above with cables, allows for blameless drilling to take place, but allows for the movement of the platform, which will inevitably be affected by faulting wind and water currents. There are two basic types of offshore drilling rigs those that can be moved from place to place, allowing for drilling in multiple locations, and those rigs that are permanently placed. Moveable rigs are ofttimes used for exploratory purposes because they are much cheaper to use than permanent platforms.Once large deposits of hydrocarbons have been found, a permanent platform is built to allow their extraction. The sections below describe a number of different types of negotiable offshore platforms. Drilling barges are used mostly for inland, shallow water drilling. This typically takes place in lakes, swamps, rivers, and canals. Drilling barges are large, floating platforms, which must be towed by tugboat from location to location. Suitable for still, shallow waters, drilling barges are not able to withstand the water movement experienced in large open water situations.Semisubmersible rigs are the most common type of offshore drilling rigs, combining the advantages of submersible rigs with the ability to drill in deep water. A semisubmersible rig works on the same rule as a submersible rig through the inflating and deflating of its lower hull. The main difference with a semisubmersible rig, however, is that when the aerate is let out of the lower hull, the rig does n ot submerge to the sea floor. Instead, the rig is partially submerged, but still floats above the drill site.When drilling, the lower hull, filled with water, provides stability to the rig. Semisubmersible rigs are held in place by huge anchors, each weighing upwards of 10 tons. These anchors, combined with the submerged portion of the rig, ensure that the platform is stable and safe enough to be used in turbulent offshore waters. Semisubmersible rigs can be used to drill in much deeper water than the rigs mentioned above. Drillships are exactly as they sound ships intentional to carry out drilling operations. These boats are specially designed to carry drilling platforms out to marine locations.A typical drillship will have, in addition to all of the equipment normally found on a large ocean ship, a drilling platform and derrick located on the middle of its deck. In addition, drillships master a hole (or moonpool), passing right through the ship down through the hull, which all ows for the drill string to extend through the boat down into the water. Drillships are often used to drill in very deep water, which can often be turbulent. Drillships use what is known as dynamic positioning systems.Drillships are equipped with electric motors on the underside of the ships hull, capable of propelling the ship in any direction. These motors are integrated into the ships computer system, which uses satellite positioning technology, in conjunction with sensors located on the drilling template, to ensure that the ship is directly above the drill site at all times. Offshore oil drilling creates disasters not only in the ocean or seas, but generates explosions of the oil rig itself. Bits and pieces of the rig can rust at the bottom of the ocean and endanger precious reefs and homes of animals.I mean offshore oil drilling is a mistake and should be limited around the world. There are plenty of renewable energy sources to survive off of. Fuels can be costly but the envir onment would be a safer place to live in. Having a limited supply of oil can unless millions of aquatic lives and provide worries from environmentalists will be satisfied. Drilling should be banned all together to save human lives as well. Many have been lost because of accidental explosives. Hopefully oil drilling will end soon and promote the general welfare of living in a clean, oil-free environment.Works Citedhttp//www.freerepublic.com/ nidus/f-news/2525743/postshttp//english.aljazeera.net/business/2010/03/201033118235692566.html
