The Kulluk and the Xiang Rui Kou heavy lift vessel are no longer in Captains Bay -- but the ships aren’t leaving Unalaska just yet. The vessels have been moved to Broad Bay, says Coast Guard Lt. Jim Fothergill. They’ll stay there until Friday, when they’re scheduled to leave for Singapore.

Shell has pushed back the departure twice now. Fothergill says he doesn’t know the reason for the delays, and a Shell spokesman did not return requests for information.
