31 December 2012. A Coast Guard Air Station Kodiak MH-65 Jayhawk helicopter delivers personnel to the conical drilling unit Kulluk, southeast of Kodiak, Alaska. 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.
