BP Replaces Containment Cap Over Broken Oil Well

A cap was back in place on BP's broken oil well after a deep-sea blunder forced crews to temporarily remove what has been the most effective method so far for containing some of the massive Gulf of Mexico spill.

Engineers using remote-controlled submarines repositioned the cap late yesterday after it had been off for much of the day. It had captured 700,000 gallons of oil in 24 hours before one of the robots bumped into it late in the morning.

BP says it has reinstalled a containment cap on its blown-out well in the Gulf of Mexico after an accident unleashed a torrent of oil.

BP was forced to remove the cap after an underwater robot bumped into the venting system.

Gas had risen through the vent that carried warm water down to prevent ice-like crystals from forming in the cap.
