New cap put on Gulf well in effort to contain oil

NEW ORLEANS — A new cap has been installed on the leaking well in the Gulf of Mexico, offering hope of containing the gusher for the first time since BP’s deepwater rig exploded in April.

BP officials said Monday evening the cap was mounted on the well after two days of preparing the site and a day of slowly lowering it into place.

The company plans to run tests starting Tuesday to see if the cap can withstand pressure.

The old cap, removed Saturday, did not have a tight fit and allowed crude to escape.

The new cap will enable BP to capture all the oil and funnel it up to ships.

BP is drilling two relief wells so it can pump mud and cement into the leaking well for a permanent fix.

THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP’s earlier story is below.

NEW ORLEANS (AP) — Undersea video showed BP robots landed a new, tighter-fitting cap on top of the gushing Gulf of Mexico oil leak Monday, raising hopes that the crude could be kept from polluting the water for the first time in nearly three months.

Placing the cap on top of the leak was the climax of two days of delicate preparation work and a day of slowly lowering it into position. The capping project — akin to building an underwater Lego tower — is just a temporary fix, but the oil giant’s best hope yet for containing the spill.

Around 6:30 p.m. CDT, live video streams trained on the wellhead showed the cap being slowly lowered into place, 11 hours after BP Chief Operating Officer Doug Suttles said the company was close to putting the seal in place. Company officials did not comment on the operation Monday evening or say how long it would take to latch the cap permanently in place.

From the White House to Gulf Coast marinas and town halls, all eyes were on the slow, deliberate process unfolding a mile below the sea. President Barack Obama is getting repeated updates, his adviser David Axelrod said. Residents on the coast were skeptical, though, and know that even if the gusher is contained, the disaster will be far from over.

The 18-foot-high, 150,000-pound metal cap will be tested and monitored to see if it can withstand pressure from oil and gas starting Tuesday morning for six to 48 hours, according to National Incident Commander Thad Allen. The cap will be tested by closing off three separate valves that fit together snugly like pairs of fists, choking off the oil and blocking it from entering the Gulf.

BP doesn’t want the flow of oil to stop instantaneously, said Don Van Nieuwenhuise, director of Professional Geosciences Programs at the University of Houston. Shutting the oil off too quickly could cause another explosion, he said.

“Rather than like a train running into a brick wall, it’ll be more like putting the brakes on slowly,” he said. “That’s what they’re aiming for. You can keep the brakes on and everyone arrives alive, or you hit the wall and have big problems.”

Even if the cap works, the blown-out well will still be leaking. But the newer, tighter cap will enable BP to capture all the oil, or help funnel it up to ships on the surface if necessary.

One of those ships, the Helix Producer, began operating Monday and should be up to its capacity of collecting roughly 1 million gallons of oil a day within a few days, Chief Operating Officer Doug Suttles said.

A permanent fix will have to wait until one of two relief wells being drilled reaches the broken well, which will then be plugged up with drilling mud and cement. That may not happen until mid-August.

Meanwhile, the Obama administration issued a revised moratorium on deep-water offshore drilling Monday to replace the one that was struck down by the courts as heavy-handed. The original moratorium halted the approval of any new permits for deep-water projects and suspended drilling on 33 exploratory wells in the Gulf. The new ban, in effect until Nov. 30, does not appear to deviate much from the original moratorium, as it still targets deep-water drilling operators while defining them in a different way.

Work on the new capping operation began Saturday with the removal of a leaky cap that captured about 1 million of the 1.5 million to 2.5 million gallons of oil the government estimates is spilling from the well every day.

Engineers will be watching pressure readings. High pressure is good, because it would mean the leak has been contained inside the wellhead machinery. But if readings are lower than expected, that could mean there is another leak elsewhere in the well.

“Another concern right now would be how much pressure the well can take,” and whether intense pressure would further damage the well, said Eric Smith, associate director of the Tulane Energy Institute.

Gulf residents closely watched the operation, knowing the damage already done to the biologically rich Gulf and the coast’s two leading industries, fishing and tourism.

“I think we’re going to see oil out in the Gulf of Mexico, roaming around, taking shots at us, for the next year, maybe two,” said Billy Nungesser, president of Louisiana’s oil-stained Plaquemines Parish. “If you told me today no more oil was coming ashore, we’ve still got a massive cleanup ahead.”

BP “can’t do much, but they know how to drill wells,” dock master Jimmy Beason said at a marina in Orange Beach, Ala. “I think that by the end of the month it will be stopped, and this work with the cap is part of it. I see the light at the end of the tunnel.”

As of Monday, between 89 million and 176 million gallons of oil had poured into the Gulf, according to government estimates.
