An enormous Shell Oil offshore drilling rig ran aground on an island in the Gulf of Alaska on Monday night after it broke free from tow ships in rough seas, officials said.
The rig, the Kulluk, which was used for test drilling in the Arctic last summer, is carrying about 139,000 gallons of diesel fuel and 12,000 gallons of lubricating oil and hydraulic fluid, the officials said.
A Coast Guard helicopter flew over the rig after the grounding at 8:48 p.m. and “detected no visible sheen,” said Darci Sinclair, a spokeswoman for a unified command of officials from Shell, Alaskan state agencies and other groups that has been directing the response since the troubles with the rig began last Thursday.
