OiL SpilL... a big disaster



An oil spill is the release of liquid petroleum into the environment as a result of human activity. The term often refers to marine oil spills, where oil is released into the ocean or coastal waters. Oil can refer to many different materials, including crude oil, refined petroleum products (such as gasoline or diesel fuel) or by-products, ships' bunkers, oily refuse or oil mixed in waste. Spills take months or even years to clean up. The fate, behavioral and environmental effects of spilled oil can vary, depending upon the type and amount of material spilled. petroleum products such as diesel and gasoline are more likely to mix in the water column and are more toxic to marine life, but tend to evaporate more quickly and do not persist long in the environment. With large numbers of people living and depending on coastal areas for fishing and tourism throughout the world, the consequences of oil spills can be serious. Such possibilities have caused outcries for oil companies, ship owners, and shipbuilders to share the responsibility of preventing such a disaster. As oil is lighter than water, and does not quickly decompose, it can remain on the surface for a long time. As it is also flammable, oil spills can fuel ocean fires.
One solution to mitigate the effects of an oil spill is through being able to contain and effectively treat spilled oil. A new step being developed in preventing oil damage is through installations of systems made for Fast Oil Recovery (FOR) of oil from wrecked ships.
