Tug boats set lines and begin towing Shell Oil's drill ship Kulluk as it is prepared to be loaded onto the Xiang Rui Kou heavy lift transport ship in Captains Bay in Unalaska. The Kulluk, a circular barge with a diameter as long as nearly three basketball courts, broke away from its towing vessel in late December on its way to a shipyard in Washington State. On New Year's Eve it ran aground off a remote Alaska Island near Kodiak Island. It was pulled off six days later but requires repairs. The Kulluk will be loaded onto the heavy lift vessel for transport to a shipyard in Asia.
