Oil vessel runs aground off Alaska
A large drilling vessel belonging to oil major Shell ran aground off Alaska last night after drifting in stormy weather, company and government officials have said.
The drilling barge, the Kulluk, broke away from one of its tow lines yesterday afternoon and was driven to rocks just off Kodiak Island, where it grounded at about 9pm Alaska time, officials said.
The 18-member crew had been evacuated by the Coast Guard late on Saturday because of risks from the storm.
With winds reported at up to 60 miles an hour (100km/h) and Gulf of Alaska seas of up to 35 ft (10.6m), responders were unable to keep the conically-shaped vessel from grounding, said Coast Guard Commander Shane Montoya, the leader of the incident command team.
"We are now entering into the salvage and possible spill-response phase of this event," Cmdr Montoya told a news conference late last night in Anchorage.
There is so far no known spill and no reports of damage, but the Kulluk has about 155,000 gallons of fuel on board, Cmdr Montoya said.
The grounding of the Kulluk, an Arctic-class drill vessel weighing nearly 28,000 gross tonnes, is a blow to Shell's $4.5 billion (€3.4 billion) offshore programme in Alaska.
Shell's plan to convert the area into a major new oil frontier has alarmed environmentalists and many Alaska natives, but excited industry supporters.
Environmentalists and native opponents say the drilling programme threatens a fragile region that is already being battered by rapid climate change.
"Shell and its contractors are no match for Alaska's weather and sea conditions either during drilling operations or during transit," Lois Epstein, Arctic programme director for The Wilderness Society, said in an email.
"Shell's costly drilling experiment in the Arctic Ocean needs to be stopped by the federal government or by Shell itself given the unacceptably high risks it poses to both humans and the environment," she added.
The leading Democrat on the US House of Representatives' Natural Resources Committee, Ed Markey, of Massachusetts, said in a statement that this incident and others illustrated the perils of oil drilling in the Arctic.
"Oil companies cannot currently drill safely in the foreboding conditions of the Arctic, and drilling expansion could prove disastrous for this sensitive environment," Mr Markey said.
The Kulluk's woes began on Friday, when the Shell ship towing it south experienced a mechanical failure and lost its connection to the drill vessel.
That ship, the Aivik, was reattached to the Kulluk early yesterday morning, as was a tug sent to the scene by the operator of the Trans Alaska Pipeline System. But the Aivik lost its link yesterday afternoon, and the tug's crew could only try to guide the drill barge to a position where, if it grounded, "it would have the least amount of impact to the environment", Mr Montoya said.
The Kulluk was used by Shell in September and October to drill a prospect in the Beaufort Sea. It was being taken to Seattle for the off-season when the problems began on Friday.
Susan Childs, emergency incident commander for Shell, held out hope that a significant spill from the drill vessel was unlikely.
"The unique design of the Kulluk means the diesel fuel tanks are isolated in the centre in the vessel and encased in very heavy steel," she told the news conference.
Shell is waiting for weather to moderate "to begin a complete assessment of the Kulluk," she said. "We hope to ultimately recover the Kulluk with minimal or no damage to the environment."
The Kulluk was built in 1983 and had been slated to be scrapped before Shell bought it in 2005. The company has spent $292 million since then to upgrade the vessel.
Shell's Arctic campaign has been bedevilled by problems. A second drill vessel, the Discoverer, was briefly detained in December by the Coast Guard in Seward, Alaska, because of safety concerns. A mandatory oil-containment barge, the Arctic Challenger, failed for months to meet Coast Guard requirements for seaworthiness and a ship mishap resulted in damage to a critical piece of equipment intended to cap a blown well.
