Oil spill quick fix dashed

Hopes of a quick fix to stop oil from the
Deepwater Horizon oil rig gushing into the Gulf of Mexico were dashed on
Saturday, when a build-up of crystallised gas blocked the pipes in the huge
metal containment tower, which then had to be lifted from the seabed.

While BP engineers wrestled with the
problem, reports came in of the first tar balls and tar beads washing up on the
white sand beaches of Dauphin Island, off Alabama.

The metal tower, specially designed and constructed
to cap the leak, is the height of a four-storey building and weighs 100 tonnes.
The hope was it would hold the oil still gushing out of the well, which could
then be siphoned out of the top, but the blocked pipes made that impossible.

The chief operating officer, Doug Suttles,
said: “I wouldn’t say it’s failed yet. What I¬†would say is what we
attempted to do last night didn’t work because these hydrates plugged up the
top of the dome.”

He predicted that it could take another 48
hours to find a resolution.

The problem is blamed on methane gas,
partly frozen into slush by the cold temperatures on the seabed at 1,500 metres
(5,000ft). Engineers anticipated the problem, but not the volume of the gas
build-up in the pipes. Suttles said that solutions could include heating the
area, or adding methanol to break up the hydrates.

Meanwhile, oil continues gushing into the
Gulf of Mexico at a rate of 4,000 barrels a day or more.

Teams were sent by BP to Dauphin Island to
test the tar washing up on the beaches, to establish whether it really does
come from the spill. They will also lay down clusters of oil-absorbing
synthetic fibres, and build storm-fencing along the beach.

A spokesman for the spill response command
said that tar washing ashore on Alabama’s beaches was common. However, local
residents, holding up fist-sized chunks, said they had never seen anything like
it before.

Construction workers have been racing
around the clock, all weekend, to finish laying a three-mile boom across the
mouth of Mobile Bay, Alabama, the ninth largest port in the US. The boom,
tethered to a line of pilings driven into the sea bed, is being built with a
double gate to allow ships to pass through. Vessels will be held between the
gates, checked for oil contamination, and cleaned if necessary before being
allowed to proceed. The bay is also home to beach resorts and commercial and
leisure fisheries, including oyster beds.

Fishing restrictions mean thousands of
boats have been tied up idle. Oyster processing plants are running out of
supplies and shutting down, putting hundreds of people out of work.

Wayne Eldridge, owner of J&W Marine
Enterprises, an oyster plant operator, said: “I’m screwed. The biggest
thing is I’ve got 35 people unemployed there.”
