Shell rig grounds in Alaska

A U.S. Coast Guard helicopter crew from Air Station Kodiak conducts the 13th hoist of 18 crewmen from the Arctic-class mobile drilling unit Kulluk 80 miles southwest of Kodiak City, Alaska, on Dec. 29. The Aiviq, an Edison Chouest Offshore-owned 360’8″x80’x34′ offshore support vessel, lost power while towing the 266′-dia. Kulluk roughly 50 miles off the coast of Kodiak Island, Alaska. The rig has been under charter to Royal Dutch Shell since March 2012. The Kulluk sat grounded on the southeast side of Sitkalidak Island for about a week. On Jan. 6, the drilling unit was refloated and reattached to the Aiviq, whose engines had been repaired, and towed some 45 miles at an average speed of roughly 3.5 knots to Kiliuda Bay. A review of the Kulluk’s hull was completed by divers and remotely operated vehicles in mid-January.
