What are the environmental consequences of offshore drilling Research Proposal

What are the environmental consequences of offshore drilling - Research Proposal Example ost difficult and more than for land-based fitting and much of the improvement in the offshore petroleum sector revolves around overcoming these challenges. This includes a significant necessity of â€Å"Manned facilities have to to be kept above sea-level.† This can be only achieved with vast constructions with their foundations on the sea bed, like â€Å"the Troll† – A platform stationed on a depth of 300 meter. With height of 472 meter, it can be acknowledged as the biggest man-made movable construction. Type of other platforms including floating types only anchored to the sea-floor. These floating platforms trim down the construction costs but the additional security measures are required as well as apparatus for nulling out heave due to strong waves. In both of oil ridges, the ocean adds numerous hundred meters to the liquefied column in the drill string increasing â€Å"bottom hole pressure† as well as escalating the required amount of energy to lift sand and cuttings for oil-sand separation on the platform. as of modern times the emphasis of oil companies is to conduct maximum production subsea for instance amenities to split sand from oil and re-inject sand prior to pumping up to the platform. In this proces s there are no installations visible above the sea-level. Subsea installations enhance the goal of the petroleum industry of exploiting natural resources at gradually deep waters that have been inaccessible in the past. It also evades several challenges related to sea ice as in the Barents Sea. An offshore oil ridge can also be defined more or less as a small world with support utilities like cafeteria, resting quarters and administration located offshore. In the North Sea, the employees are transported on the platform by helicopter for a 2-week shift. This in turn means higher air pollution. Materials and wastes are transported by the means of ship and it is required to be delicately maneuvered due to the inadequate floor area on the platform. As of
