This video helps us understand the safety of supertankers.
Random Thoughts About Supertankers:
Not too many years ago the Exxon Valdez supertanker went aground and spilled eleven million gallons of crude oil into Prince William Sound.
The average length of today's four largest supertankers is close to 1,500 feet. Their cargo capacity is 3,166,353 barrels each. Every year over two billion barrels of oil are transported in supertankers.
Crude oil contains polycyclic aromatic hydrocarbons which lasts for years in sediment and marine environment.
The supertanker hull is either single hulled or double hulled. One would assume that since double hulled supertankers have more space between the oil and the water they are safer.
After the Exxon Valdez disaster the United States passed an 'Oil Pollution Act' which stated that all tankers entering US waters have to be double hulled by 2015.
Doubtless this news is extremely comforting to the sea otters and birds who died for the sake of oil.
