The Coast Guard reported two people involved in the clean-up effort died on Wednesday. This report changes the number of fatalities to 13.
The Coast Guard says BP has been forced to remove a cap that was containing some of the oil gushing into the Gulf of Mexico.
Coast Guard Adm. Thad Allen says an underwater robot bumped into the venting system. That sent gas rising through vent that carries warm water down to prevent ice-like crystals from forming in the cap.
Allen says the cap has been removed and crews are checking to see if crystals have formed before putting it back on. In the meantime, a different system is still burning oil on the surface.
Before the problem with the containment cap, it had collected about 700,000 gallons of oil in the previous 24 hours. Another 438,000 gallons was burned.
The current worst-case estimate of what's spewing into the Gulf is about 2.5 million gallons a day.
BP PLC said Wednesday that managing director Bob Dudley will head the new Gulf Coast Restoration Organization, which is in charge of cleaning up the oil spill.
Dudley won't say if the oil giant will resume deepwater drilling in the Gulf, where it's the largest oil and gas producer.
Dudley says the company will "step back" from the issue while investigating the April 20 explosion. Dudley told the CBS "Early Show" he has completed taking over the disaster response and cleanup from CEO Tony Hayward. Hayward repeatedly sparked criticism from the Gulf to the U.S. Capitol for missteps and insensitive comments.
The White House has promised an immediate appeal of a federal judge's reversal of the administration's six-month moratorium on deepwater drilling in the Gulf of Mexico. And Interior Secretary Ken Salazar said he will issue a new order imposing a moratorium that eliminates any doubt it is needed and appropriate.
Judge Martin Feldman overturned the ban Tuesday, saying the government simply assumed that because one rig exploded, the others pose an imminent danger, too. The Interior Department had imposed the moratorium last month in the wake of the BP disaster, halting approval of any new permits for deepwater projects and suspending drilling on 33 exploratory wells.
The Louisiana judge who struck down the Obama administration's six-month ban on deepwater oil drilling in the Gulf of Mexico has reported extensive investments in the oil and gas industry, according to financial disclosure reports. He's also a new member of a secret national security court.
U.S. District Judge Martin Feldman, a 1983 appointee of President Ronald Reagan, reported owning less than $15,000 in stock in 2008 in Transocean Ltd., the company that owned the sunken Deepwater Horizon drilling rig. His 2008 financial disclosure report the most recent available showed investments in more than a half-dozen other energy-related companies including Halliburton, which was also involved in the doomed Deepwater Horizon project. Feldman did not respond to requests for comment and to clarify whether he still holds some or all of these investments.
In London, British Prime Minister David Cameron's office said he would discuss BP and the oil spill in a meeting Saturday with President Barack Obama. Cameron's spokesman Steve Field told reporters Wednesday the men will discuss the beleaguered energy company during a meeting during the G-8 and G-20 summits in Canada.
