More oil gushing into Gulf after problem with cap

NEW ORLEANS (AP) — Tens of thousands of gallons more oil gushed into the Gulf of Mexico on Wednesday after an undersea robot bumped a venting system, forcing BP to remove the cap that had been containing some of the crude.
It was yet another setback in the nine-week effort to stop the gusher, and it came as thick pools of oil washed up on Pensacola Beach in Florida and the Obama administration tried to figure out how to resurrect a six-month moratorium on deepwater drilling.
When the robot bumped the system just before 10 a.m. Wednesday, gas rose through the vent that carries warm water down to prevent ice-like crystals from forming, Coast Guard Adm. Thad Allen said.
Crews were checking to see if crystals had formed before putting it back on. BP spokesman Bill Salvin could not say how long that might take.
“We’re doing it as quickly as possible,” he said.
Before the problem with the containment cap, it had collected about 700,000 gallons of oil in 24 hours. That’s oil that’s now pouring into the Gulf. Another 438,000 gallons was burned on the surface by a different system that was not affected by the issue with the cap.
A similar problem doomed the effort to put a bigger containment device over the blown-out well in May. BP had to abandon the four-story box after the crystals called hydrates clogged it, threatening to make it float away.
The smaller cap, which had worked fine until now, had been in place since early June. To get it there, though, crews had to slice away a section of the leaking pipe, meaning the flow of oil could be stronger now than before.
The current worst-case estimate of what’s spewing into the Gulf is about 2.5 million gallons a day. Anywhere from 67 million to 127 million gallons have spilled since the April 20 explosion on the Deepwater Horizon rig that killed 11 workers and blew out the well 5,000 feet underwater. BP PLC was leasing the rig from owner Transocean Ltd…
