One of the tanks fastened to the shipwrecked Costa Concordia cruise liner to help prepare it for removal to land has shifted due to a tangled chain.

The consortium overseeing the operation said technicians were working to reconnect the chain properly, and that the "situation was under control."

Workers began fastening tanks to the ship last week. The tanks, 19 in all, were being filled with water to help stabilize the Concordia, now resting on an artificial seabed after it was set upright in September.

The liner capsized off the Italian island of Giglio in 2012 after striking a reef. Thirty-two people died. The ship's captain is being tried on manslaughter and other charges.

The Concordia will be floated to a port, yet to be determined, for scrapping.
