Taking oil spills seriously
In 1989 an oil tanker, the Exxon Valdez struck a rock and spilled 34,000 tonnes, (about one third of its cargo) of thick polluting crude oil into the sea. This oil spill devastated a pristine Arctic environment.
Like most oil tankers in those days it was a single hull oil tanker. Many people thought at the time that if the Exxon Valdez had been built with a double hull only a small amount of oil would have been lost.
Learning from this disaster all the world’s 2000 single hull tankers are being replaced. Since 1996 only double hull tankers have been built and the last single hull tankers will be taken out of service by 2010.
