Now let's stop lying on oil like a rainbow falling to the ground. As a child I always wish for more beautiful whirlpools to deform to the ground. When it rained, people knew that oil movement had already made me feel that I lost my opinion of my time. A few minutes after midnight on March 24, 1989, Exxon Valdez Super Tanker collided with a coral reef of Prince William Sound, Alaska.
VLCC tankers can carry 2 million barrels (320,000 cubic meters) of crude oil. This is about 8 times the leak of well-known Exxon Valdez oil. In this accident, in March 1989 the ship rolled over and dumped 260,000 barrels of oil (41,000 cubic meters) into the sea. Scientists, managers and volunteers have been murdered for over 400,000 seabirds, about 1,000 sea otters and numerous fish. . But considering the amount of oil transported by sea, tanker owners often claim that industry safety records are very good and that the proportion of shipped oil is negligible. The International Tanker Shipowners' Association said, "The accidental oil spill over the past 10 years was at a record low of 1 / 10th of a tenth or a tenth of the past, more than doubled "
Because the time of oil is known, oil spills are also known. Oil spill is the release of liquid petroleum hydrocarbons into the environment by human activity and is regarded as a form of pollution. It refers to the oil spill of the oceans, which is mainly released into the ocean and coastal waters. Oil spill involves oil spills from tankers, oil drilling equipment, offshore platforms, etc. In addition, oil may enter from penetration of natural oil. There are three main modes of oil spill and transport of petroleum products. The first is smooth () surface transport. This is very important as thickness, shape, and position affect the ability of dispersants to act on them. The next step is vertical transport (initial dilution of dispersed oil is done) (). The last step is horizontal underground transport, which completely dilutes the oil. ()
