BP Plans to Replace Containment Cap Next Month
Last Updated 4:16 p.m. ET
As officials reported a gradual increase in the amount of oil being captured from a spewing wellhead at the bottom of the Gulf of Mexico on Monday, BP PLC said it plans to replace the cap collecting the crude with a slightly bigger device next month.
The newer cap will "provide a better, tighter fit" than the current one collecting roughly one-third to three-fourths of the oil gushing daily from the sea floor, company spokesman Robert Wine told The Associated Press.
The oil began spewing forth after a BP oil rig explosion April 20 and recently increased after officials cut the pipe carrying the flow as part of the latest containment effort.
BP believes the bigger cap will fit over more of the outflow pipe than the current cap, Wine said, but the change will allow the oil now being collected to again spew out into the Gulf during the changeover.

Wine acknowledged the frustration people must have when they look at the video feeds from undersea that show a lot of oil still flowing into the sea.
"We want to capture every drop of oil that is still leaking," he said. "We want to protect the coastline and repair the coastline that has been damaged."
Officials say the current cap is collecting more than 460,000 gallons of oil per day. BP continues to drill relief wells in hopes of a permanent solution.
Wine said the estimate of the proportion of gushing oil being collected is based on the government's contention that the containment cap is collecting 466,200 gallons of oil of the roughly 604,800 to 1,260,000 it believes is coming out daily.
Cutting the riser likely increased the flow of oil by 20 percent from the 504,000 to 1,050,000 gallons the government contends was coming out previously, Wine said.
Coast Guard Adm. Thad Allen, the government's point man for the oil spill response, provided the updated oil-collection figure during a news conference earlier Monday at the White House.
Meanwhile, President Barack called the Gulf Coast ecosystem and its people resilient and reassured Americans that "we will get through this crisis", but that it will take time and effort.
"The economic impact is going to be substantial and ongoing," Mr. Obama said.
Surrounded by Cabinet members, Mr. Obama and top federal officials were briefed on the government's battle against an unprecedented oil spill by Coast Guard Adm. Thad Allen, who is overseeing the government's efforts in dealing with the tragedy.
"Even if we are successful in containing some or much of this oil, we are not going to have this problem solved until we have the relief well completed," Mr. Obama said.
President Obama told reporters after the briefing that the people of the Gulf coast "are going to need help from the entire country," but that he is determined that the region be restored to a condition better than it was before the BP well blew out on April 20.
Speaking at a White House press briefing this morning, Admiral Allen said said that the emphasis on operations is shifting as the spill disaggregates itself.
"We're no longer dealing with a large, monolithic spill, but hundreds of thousands of patches of oil going in different directions," Allen said. "We've had to adapt to meet that threat."
"We're adapting to an enemy that changes," he said. "With currents and wind, as the spill has changed, our response has changed. "
Allen said that in the last 24 hours, the Discovery Enterprise, the ship siphoning off crude from the broken wellhead, produced 11,000 barrels of oil, or 462,000 gallons. This compares to the 6,000 barrels collected the first day the wellhead was capped, and is approaching a projected production of 15,000 barrels a day.
Judging by flow rate estimates supplied by the government, the cap could be collecting anywhere from 37 percent to 77 percent of the oil still gushing out.
The inverted funnel-like cap is being closely watched for whether it can make a serious dent in the flow of new oil. It's not clear how much oil is still escaping from the well, but more is being collected as more vents on the cap are closed. The process is gradual because crews need to keep water and gas from creating a slush that thwarted a previous containment effort.
Federal authorities have estimated the ruptured pipe is leaking between 500,000 gallons and about 1 million gallons a day.
Allen said BP was moving a second vessel, called the Q4000, to join the Discover Enterprise to boost capacity to a combined 20,000 barrels a day, and to close the venting vales on the containment cap. Once the wellhead is completely capped - BP's collecting ships cannot yet process the full amount of oil escaping - the actual flow rate of oil can be determined.
He said a command post in Alabama is in control of skimming vessels working to collect smaller patches of oil off the Mississippi, Alabama and Florida coasts. Allen said they were working to increase the number of ships available, which is currently at 1,500, and will move Coast Guard units in as well, including a cutter conducting command and control, and helicopters for surveillance.
He said BP was also working on creating a permanent connector for the collection hoses that can be shut in the event of a hurricane.
A wellhead cap at the bottom of the Gulf of Mexico is slowly pinching off a geyser of oil spewing from the earth, but there's no containing much of the crude that's already escaped, a reality becoming increasingly evident on the region's beaches.
More Tar Balls Expected in Middle of Florida Panhandle
The patchy oil slick from the ruptured pipe off Louisiana has stained beaches and marshes in spots along more than 100 miles of coast from Louisiana to the Florida Panhandle, and a sheen on the surface was spotted as far as about 150 miles west of Tampa, Fla.
The tourist hotspot of Panama City Beach, in the middle of the Panhandle, expected oil to reach its famous beaches within 72 hours, which would mark a new easternmost point for the oil washing ashore.
"We have just entered the area of uncertainty for about half of our beach," said Dan Rowe, president of the city's convention and visitors bureau. "We are still hoping tar balls don't show up here, but we are putting the contingency plans in place and everyone is out there looking at the beach and inspecting it."
Tar balls continued to roll onto shore Monday morning farther west at Pensacola Beach, leaving a distinct line in the sand from the high-rise condos above as the sun rose. Beach walkers had to stay between the line of dime- and quarter-size tar balls and the retreating surf or risk getting the gummy, rust-staining gunk stuck to their feet.
Jody Haas, a tourist from Aurora, Ill., was among the few walking the beach early Monday after a crowded weekend here. Haas, who had visited the beach before, said it was not the same.
"It was pristine, gorgeous, white sand," she said. "This spot is light compared to some of the other spots farther down and (the tar) is just everywhere here. It's just devastating, awful."

At Barataria Bay, La., just west of the mouth of the Mississippi River, large patches of oil the consistency of pancake batter in the still waters Monday. A dead sea turtle caked in brownish-red oil lay splayed out with dragonflies buzzing by.
The Barataria estuary, which has become one of the hardest-hit areas, was busy with shrimp boats skimming up oil and officials in boats and helicopters patrolling the islands and bays to assess the state of wildlife and the movement of oil.
On remote islands, oil visibly tainted pelicans, gulls, terns and herons.
Also falling victim to the oil are those who make their living off the Gulf by fishing or operating tourist traps along the region's white-sand beaches. Allen said Monday that BP needs to make improvements on getting money to individuals and businesses harmed by the spill.
"It's not a core competency of BP so we're trying to get them some help," Allen said.
In Panama City Beach, which just opened a major airport to capture fly-in tourists, officials were fighting to keep their traditional drive-in customers while they still could, Rowe said.
"The folks here are very concerned about the oil out there," Rowe said. "We are working so diligently to get the word out there to the public that are beaches are clean right now."
Officials put out a report late Sunday that dead, oiled birds had been found in Texas but retracted it Monday morning. U.S. Fish and Wildlife Service spokeswoman Nancy Brown blamed the mistake on a clerical error.
BP said Monday that the cost of the response has reached about $1.25 billion. The company said the figure does not include $360 million for a project to build six sand berms meant to protect Louisiana's wetlands from spreading oil.
A Long-Term Battle
The battle to contain the oil is likely to stretch into the fall, Allen said Sunday on CBS' "Face the Nation." The cap will trap only so much of the oil, and relief wells being drilled won't be completed until August.
Allen elaborated on his comments over the weekend, acknowledging the full cleanup would take much longer. He said that "dealing with the oil spill on the surface will take a couple of months" but that the process of getting oil out of marshlands and other habitats "will be years."
White House press secretary Robert Gibbs said that penalties eventually leveled against BP would be based on how much oil has been spilled, and the government will use its own figures.

Allen said BP needs to make improvements on getting money to individuals and businesses who have been harmed by the spill.
"We'd like them to get better at claims," Allen said.
Individuals have begun to get partial payments, but Allen said the government is pushing for that to be "routinized" so that people know to expect regular checks. The problems with business claims are worse, he said. Because such claims require more complicated documentation and processing, they are going slower and government officials were meeting with BP on Monday to try to speed it up, Allen said.
"That appears that may be a little cumbersome right now," he said. "We think they need to do that better and quicker."
"It's not a core competency of BP so we're trying to get them some help," Allen said.
Allen wouldn't directly answer whether he trusted BP, but he said the company is cooperating with the government's demands for action and information.

like the idea of interrupted thread bolts, been thinking the same myself, perhaps quarter screw but longer such as used on an artillery gun breech?
i'm damn sure that you or i could easily fix this problem, you seem to be far more qualified than i am on the engineering score, but to put it simply, if i can knock up a quick solution based on existing technology that will seal and cap off the well properly, and not leak 50% of it out there for the world to wade in, i'm damn sure that a decent fully qualified guy who knew more about the actual equipment then we do could do a lot better if he was left to do it.
something stinks here and it's not the smell off the crude.
simple isn't it?
are you seriously telling me at that depth you can't cut the heads off the bolts on the flange and replace them?
if you can but the pipe, you can cut the heads off the bolts.... if you can cut the heads off the bolts you can take the flange off....
if you can take the flange off you can replace it with either another damn pipe or a short pipe with a valve on and shut the lot off.
i think that's pretty straightforward and simple.... the technology to do it is already there use the gear they already use on cutting and replacing sections on oil pipelines.... if you're worried about the robots not being able to work the bolts you modify the nuts and bolts....
you put a cone on the end of the bolt and use a longer nut with a tapered start to make it easier.
my god i'm no engineer, but that's so damn simple, i'm suprised they ain't tried it already.
There is good logic in cutting off the bolts, in my non-engineer opinion, asince there is a precison machined surface which can be referenced to clamp to, but your suggestion is possibly more complex than it needs to be.
Little info has been released on the structure of the flange, but if it is considered a gas-tight weld generated by the crushing pressure of the bolts rather than a crushable gasket, then the upper half of the flange may remain unreliably stuck to the lower half of the flange once the bolts are cut, and this would add an undesirable variable to the equation (contemplatable if the IGES blueprint files of the well were released).
I do wish BP would release full CAD blueprints of the wellhead, as I'd be modeling a two-week-'til-fabricated ductile iron solution in the next two days if the data was available, but it is not, and I'm in no position to gain this data. Well, if I got the data I'd be modeling a non-engineered and non-managed fix as soon as it arrived. BP seems only interested in managed fixes, not engineered fixes or my type of fix suggestion.
What IS a constant is the existing upper and lower flange, and as bolted together it is likely a rock-solid hardpoint to bolt and seal an extreme-pressure repair fixture to. The new riser pipe is also a blueprinted entity which is perfect for completlely sealing the upper segment of the improvised fixture at extreme pressures.
Without even removing the current leaking cap, a nodular iron casting can completely encase and seal the wellhead to the riser pipe using crushable energy directors machined into the datum surfaces and cylinders. Yeah, "crushable energy directors" ain't exactly searchable, but "ultrasonic energy directors" are, and the ductile translation is the same thing: A gas tight weld which will not leak oil at relevant pressures. I'm sure ther are engineers that know what is required.
One mile down is not a place for rubber seals. Future talk of rubber seals in such a case needs to be discounted as "management sourced", not engineering sourced. Not that I would know. I don't.
When I learned a rubber gasket was going to provide a base seal for the current cap, I could only think the "waxed gasket" used on toilet bases, suitable for pressure differentials up to about 0.5 psi, the equivalent of a very large turd. Since steady-state pressure differentials of 20,000 psi, and impulse differentials of 40,000 psi must be anticipated in this particular case, I would really like to see the rubber gasket replaced by a ferritic/pearlitic nodular iron energy director in an assembly that was finite element modeled to suport the stresses.
Anyhow, like you, I am an observer. I have no idea why ANY solution would take longer than two weeks from inception until completion, but BP has made one thing clear from the start: Engineering is subservient to management, and management is subservient to golfing. If a technician or engineer advises there is an issue, management is empowered to override them for the sake of the shareholder. Well, this is what I got from the early news reports. Not sure how it is now. I haven't heard of any shakeups at BP, so I guess the status remains quo.
As for the longer nut you suggest, I am personally in favor of longer studs with strategically intermittent threading to permit rapid fixture deployment and removal, but we may be on the same page. For now, both of us must apparently sit by and watch fixtures being applied to the well which look remarkably like flat welded steel plate attached to well piping. Not very satisfying, especially since they have not been working.
Public release of IGES files would be appreciated. It's not like anyone is going to go out an copy the design of this particular wellhead.
I think a couple of well placed, directional explosive charges, would shut this down. It would make it harder for them to access the well later, but I've talked to some explosive experts, who say that with the proper budget, they think it would work. Some of the same technology that we used to seal flaming gushers in Kuwait.
I agree that a few charges might work well in taking care of things. I just think that they should be planted at BP's office.
And today, the Gulf States, the same people who put Bush/Cheney in - are mad that the oil spill is destroying their way of life.
Do you think that the schools in the Gulf States don't teach the concept of Cause and Effect? It sure sounds like it.
I think a lot of the democrats would like Obama to punish those states, from some of the posts I've read.
