The arduous process of lowering the four-story containment dome and getting it in place is expected to continue into the weekend. The technique has never been attempted at the depth of the leak spewing from the sunken oil rig, officials said.
"If all goes according to plan by early next week, we hope to make it operational," said Doug Suttles, chief operating officer of BP. "As we always do, though, we stress this has never been done before. We'll likely encounter numerous challenges, but we'll remain committed to make it work."
The stakes are high for the beleaguered oil company and the many residents of coastal Louisiana who make their living from fishing in the Gulf.
Oil washed ashore on Louisiana's barrier islands and drifted west past the mouth of the Mississippi River on Thursday. An ominous pinkish-orange foam mixture of seawater and crude oil streaked across large stretches of water in the northern Gulf and turned up on the shores of the Chandeleur Islands, off southeastern Louisiana.
The slick has been spreading across the northern Gulf of Mexico since late April, when BP's drilling rig Deepwater Horizon blew up and sank about 40 miles off the mouth of the Mississippi River. Eleven missing workers who were aboard the rig are presumed dead.
Efforts to shut down the well have failed, leaving it spewing about 210,000 gallons (5,000 barrels) of oil per day into the Gulf, and concern is rising that the oil could kill wildlife and damage livelihoods for thousands in the Gulf states.
BP has conducted more control burns in an effort to destroy "several thousand" barrels of oil on the surface Wednesday, Suttles said.
But the real hope for quelling the massive surge of oil was the containment dome.
The hope is that the container will collect the leaking oil, which would be sucked up to a drill ship on the surface. If the operation is successful, BP plans to deploy a second, smaller dome to deal with a second leak in the ruptured pipe.
Adm. Thad Allen, commandant of the Coast Guard, said he is keeping the faith that the containment dome will work.
"I think we're all hopeful that this will have an impact on this leak," Allen said. "It's been done before, but never at these depths and you think it goes to show the amount of effort that's going in to try everything potential to diminish the oil coming out of the ocean floor but this will be difficult."
