31 December 2012. The tow vessel Aiviq (left) and the tug Alert tow the conical drilling unit Kulluk through rough seas southeast of Kodiak, Alaska. Response crews have been fighting severe weather in the Gulf of Alaska while working with the Kulluk. Days of effort trying to guide a mobile offshore drilling rig through stormy Alaska seas hit a crisis Monday night when crew members were forced to disconnect the rig from its last remaining tow line and the vessel went aground on a small island south of Kodiak.
