NEW ORLEANS — Robotic submarines working a mile underwater removed a leaking cap from the gushing Gulf oil well Saturday, starting a painful trade-off: Millions more gallons of crude will flow freely into the sea for at least two days until a new seal can be mounted to capture all of it.
There's no guarantee for such a delicate operation almost a mile below the water's surface, officials said, and the permanent fix of plugging the well from the bottom remains slated for mid-August.
"It's not just going to be, you put the cap on, it's done. It's not like putting a cap on a tube of toothpaste," Coast Guard spokesman Capt. James McPherson said.
Robotic submarines removed the cap that had been placed on top of the leak in early June to collect the oil and send it to surface ships for collection or burning. BP aims to have the new, tighter cap in place as early as Monday and said that, as of Saturday night, the work was going according to plan.
If tests show it can withstand the pressure of the oil and is working, the Gulf region could get its most significant piece of good news since the April 20 explosion on the BP-leased Deepwater Horizon rig, which killed 11 workers.
"Over the next four to seven days, depending on how things go, we should get that sealing cap on. That's our plan," said Kent Wells, a BP senior vice president, of the round-the-clock operation.
It would be only a temporary solution to the catastrophe that the federal government estimates has poured between 87 million and 172 million gallons of oil into the Gulf as of Saturday. Hope for permanently plugging the leak lies with two relief wells, the first of which should be finished by mid-August.
