BP Oil Spill: Coast Guard Says Oil Could Be Contained in 3-4 Days

New containment cap could make the difference, says Coast Guard.

July 9, 2010 -- The oil spilling into the Gulf of Mexico from BP's blown-out well could be effectively contained in the next three days, National Incident Commander Thad Allen said today.

Work to install a new, tighter containment cap on the well head will begin Saturday, Allen said at a New Orleans news conference. At the same time, an additional ship to collect escaping oil, the Helix Producer I, is expected to come online Sunday.

The new cap, nicknamed Top Hat No. 10, is currently on the deck of the Discoverer Enterprise, one of the ships on the surface sucking up oil.

"We're going to attempt to remove the current cap [Saturday]," Allen said. "That will start the sequence. At the same time, we will bring the Helix Producer into production. We're going to have to take Discoverer, connected to the riser, and move it to the side."

Three vessels will be in place to capture oil from three different lines coming up from the well.

The Discoverer Enterprise is hooked up directly to the riser -- the main pipe coming from the well -- and collects 15-18,000 barrels a day. Another ship, the Q400, is connected to a smaller "choke line" and produces 5-10,000 barrels a day. The Helix Producer will connect to a third line -- known as the "kill line" -- and produce 20-25,000 barrels.

If all goes according to plan, the new cap and the ships could start to contain all the leaking oil by Monday, stopping it from escaping into the Gulf for the first time since the Deepwater Horizon drilling platform caught fire and the disaster began April 20.

"I use the word 'contained,'" Allen said. "'Stop' is when we put the plug in down below."

Still, Allen offered cautious hope that the blowout might finally come under control in the next few days.

"This is in anticipation of a weather window that will allow us seven to 10 days of good weather," Allen said. "We'd like to take advantage of that."

Depending on whose estimates one believes, the BP disaster may now be the biggest accidental oil spill in history, exceeding the 140 million gallons of oil estimated to have escaped into the Gulf of Mexico in 1979 and 1980 from the Mexican-owned Ixtoc 1 well 800 miles to the south.
