In the Gulf, struggling with the oil disaster

今年9月,深水地平线,石油钻机的跨洋向BP拥有和租用的,在历史上最深的钻油井在一个三万五千零五十英尺垂直深度。 4月20日,爆炸造成11名机组人员死亡,释放进入墨西哥湾以来已增加高达数百万加仑的石油洪流。 



In September, Deepwater Horizon, an oil rig owned by Transocean and leased to BP, drilled the deepest oil well in history at a vertical depth of 35,050 feet. On April 20, an explosion left 11 crew members dead and unleashed a torrent of oil into the Gulf of Mexico that has since added up to many millions of gallons.

Since the explosion, BP and U.S. government agencies been struggling to contain and clean up the massive flow. Meanwhile, oil continues to gush. It has already devastated stretches of the Louisiana coast, threatening wildlife and livelihoods.

On Friday, BP CEO Tony Hayward acknowledged in an interview with CNN that the situation has become an "environmental crisis and catastrophe." Also on Friday, the company said that it is continuing with its "top kill" effort to try to stem the flow of oil, and Hayward said, "I think it's probably 48 hours before we'll have a conclusive view of this."

In this slideshow, CNET takes a look at efforts over the past five weeks to contain the disaster. In addition to the overall work to stop the flow itself, other efforts have included burning off oil, using chemical dispersants, and building booms and levees.

上周四,美国地质调查局估计,水井喷出约50万至100万的产量是每年一天 - 超过21万加仑天以前估计的多。

On Thursday, the U.S. Geological Survey estimated the well has spewed about 500,000 to 1 million gallons each day--greater than a previous estimate of 210,000 gallons a day.

If the estimates are accurate, even the most conservative figures would mean this disaster is worse than the 1989 Exxon Valdez spill in Alaska. The Valdez spilled 11 million gallons into Prince William Sound.

BP said Friday that it now estimates the total cost of the response to the Deepwater Horizon disaster at $930 million.

On May 5, a containment cofferdam is hoisted onto the deck of a ship, but efforts to use that containment method proved a failure.

On May 11, a containment chamber known as a "top hat" was loaded onto a ship's deck.

The unit was lowered onto the sea floor near the flow, and undersea robots positioned the cap over the flow. This effort failed too.
