BP's top kill effort fails to plug Gulf oil leak

ROBERT, La. (AP) - The most ambitious bid yet to stop the worst
oil spill in U.S. history ended in failure Saturday after BP was
unable to overwhelm the gusher of crude with heavy fluids and junk.
President Obama called the setback "as enraging as it is
The oil giant immediately began readying its next attempted fix,
using robot submarines to cut the pipe that's gushing the oil and
cap it with funnel-like device, but the only guaranteed solution
remains more than two months away.
The company determined the "top kill" had failed after it
spent three days pumping heavy drilling mud into the crippled well
5,000 feet underwater. It's the latest in a series of failures to
stop the crude that's fouling marshland and beaches, as estimates
of how much oil is leaking grow more dire.
The spill is the worst in U.S. history - exceeding even the 1989
Exxon Valdez disaster - and has dumped between 18 million and 40
million gallons into the Gulf, according to government estimates.
"This scares everybody, the fact that we can't make this well
stop flowing, the fact that we haven't succeeded so far," BP PLC
Chief Operating Officer Doug Suttles said Saturday. "Many of the
things we're trying have been done on the surface before, but have
never been tried at 5,000 feet."
Frustration has grown as drifting oil closes beaches and washes
up in sensitive marshland. The damage is underscored by images of
pelicans and their eggs coated in oil. Below the surface, oyster
beds and shrimp nurseries face certain death. Fishermen complain
there's no end in sight to the catastrophe that's keeping their
boats idle.
News that the top kill fell short drew a sharply worded response
from President Barack Obama, a day after he visited the Gulf Coast
to see the damage firsthand.
"It is as enraging as it is heartbreaking, and we will not
relent until this leak is contained, until the waters and shores
are cleaned up, and until the people unjustly victimized by this
manmade disaster are made whole," Obama said Saturday.
In the days after the spill, BP was unable to use robot
submarines to close valves on the massive blowout preventer atop
the damaged well, then two weeks later ice-like crystals clogged a
100-ton box the company tried placing over the leak. Earlier this
week, engineers removed a mile-long siphon tube after it sucked up
a disappointing 900,000 gallons of oil from the gusher.
In the latest try, BP engineers pumped more than 1.2 million
gallons of heavy drilling mud into the well and also shot in
assorted junk, including metal pieces and rubber balls.
The hope was that the mud force-fed into the well would
overwhelm the upward flow of oil and natural gas. But Suttles said
most of the mud escaped out of the damaged pipe that's leaking the
oil, called a riser.
Suttles said BP is already preparing for the next attempt to
stop the leak that began after the Deepwater Horizon drilling rig
exploded in April, killing 11 people.
The company plans to use robot submarines to cut off the damaged
riser, and then try to cap it with a containment valve. The effort
is expected to take between four and seven days.
"We're confident the job will work but obviously we can't
guarantee success," Suttles said of the new plan, declining to
handicap the likelihood it will work.
He said that cutting off the damaged riser isn't expected to
cause the flow rate of leaking oil to increase significantly.
The permanent solution to the leak, a relief well currently
being drilled, won't be ready until August, BP says.
Experts have said that a bend in the damaged riser likely was
restricting the flow of oil somewhat, so slicing it off and
installing a new containment valve is risky.
"If they can't get that valve on, things will get much worse,"
said Philip W. Johnson, an engineering professor at the University
of Alabama.
Johnson said he thinks BP can succeed with the valve, but added:
"It's a scary proposition."
Word that the top-kill had failed hit hard in fishing
communities along Louisiana's coast.
"Everybody's starting to realize this summer's lost. And our
whole lifestyle might be lost," said Michael Ballay, the
59-year-old manager of the Cypress Cove Marina in Venice, La., near
where oil first made landfall in large quantities almost two weeks
Johnny Nunez, owner of Fishing Magician Charters in Shell Beach,
La., said the spill is hurting his business during what's normally
the best time of year - and there's no end in sight.
"If fishing's bad for five years, I'll be 60 years old. I'll be
done for," he said after watching BP's televised announcement.
The top official in coastal Plaquemines Parish said news of the
top kill failure brought tears to his eyes.
"They are going to destroy south Louisiana. We are dying a slow
death here," said Billy Nungesser, the parish president. "We
don't have time to wait while they try solutions. Hurricane season
starts on Tuesday."
