Tar balls hit Texas as oil spill cost soars

Meanwhile while a giant Taiwanese ship deployed to boost the clean-up effort remained in testing, with initial results inconclusive because of choppy waters.

The A Whale tanker cruised near the Deepwater Horizon oil spill, but Bob Grantham, a spokesman for the super-skimmer’s owner, TMT Shipping, said results were “inconclusive in light of the rough sea state we are encountering.”

Grantham said the company, working with the US Coast Guard, would continue testing the ship “to make operational and technological adjustments” for the supertanker.

The ship is believed to be able to suck up to 500,000 barrels (21 million gallons) of oily water a day through its “jaws,” a series of vents on the side of the ship.

By comparison, more than 500 smaller vessels in 10 weeks have only managed to collect some 671,428 barrels (28.2 million gallons) of oil-water mix between them.

Kathi Walsh, a spokeswoman for the unified response command, told AFP the oil skimmer is still undergoing testing by US authorities.

“The results should be available by the end of the week,” Walsh told AFP Sunday.

The tar balls from Galveston, Texas, were being tested to determine if they were from the BP oil spill, officials said.

“We immediately commenced clean-up operations and sent samples for laboratory analysis,” said Coast Guard Commander Jim Elliott, commanding officer of Marine Safety Unit Galveston.

Meanwhile, oil sheen and tar balls also were spotted Monday near the mouth of Lake Pontchartrain in Louisiana, prompting response crews to unfurl 600 feet (200 meters) of boom to prevent more oil from getting sullying the estuary.

Cleanup operations were scheduled to resume Tuesday morning, officials said.

BP said its latest estimate showed the costs to the British energy firm had risen in the past week.

“The cost of the response to date amounts to approximately 3.12 billion dollars, including the cost of the spill response, containment, relief well drilling, grants to the Gulf states, claims paid, and federal costs,” BP said.

BP’s share price has collapsed more than 50 percent since the Deepwater Horizon oil rig it leased sank on April 22, two days after a blast that killed 11 workers.

After intense pressure from President Barack Obama over the worst ever US environmental disaster, BP agreed last month to suspend its shareholder dividend and create a 20-billion-dollar fund for costs arising from the spill.

BP is also selling non-core assets to raise 10 billion dollars, while international ratings agencies have downgraded the company’s credit worthiness.

A new low-pressure center threatened the region, but the National Hurricane Center dropped an alert it had issued for a possible cyclone for the area off Louisiana.

Nearly a week after Hurricane Alex swept through the region, bad weather continued to hamper the clean-up, keeping smaller skimming vessels tied up in harbors in the affected Gulf states of Mississippi, Alabama and Florida.

Skimming and other operations have resumed in calmer seas off the coast of Louisiana, however.

Although there was no direct hit from Alex, this year’s first major Atlantic storm provided a reminder of the urgent need to clean up a disaster surpassed only by Iraqi troops’ deliberate release of crude in Kuwait during the 1991 Gulf War.

The US Navy’s MZ-3A Airship was expected to reach the Gulf Coast Tuesday to help detect oil, direct skimming vessels and search for wildlife threatened by the thick brown-orange mess.

The fractured pipe that connected the BP-leased platform to the well a mile (1,600 meters) down on the seafloor has now spewed somewhere between two and four million barrels of oil into the Gulf.

The firm’s current containment systems can only capture or flare some 25,000 barrels of oil a day, a number set to double when a third vessel is expected to be in place on Thursday.

It will likely be mid-August at the earliest before the ruptured well is permanently capped by injecting mud and cement with the aid of relief wells.
