This Jan. 10, 2013, photo provided by the U.S. Coast Guard shows an inspector climbing damaged stairs during an inspection aboard the Shell Arctic drilling rig Kulluk in Kiluida Bay, near Kodiak, Alaska. The rig grounded on Sitkalidak Island on Dec. 31, 2012, and was towed to Kiliuda Bay Jan. 7, 2013. The unified command overseeing salvage of the rig says it will release minimal information on the vessel until an assessment is complete. (AP Photo/U.S. Fish and Wildlife Service)
