A time lapse video shows the Costa Concordia as it inches away from the rock shelf where it has been stuck for more than 20 months.
In the biggest and costliest operation of its kind, salvage teams teams started the process of raising the cruise liner on Monday.
It capsized in January of 2012 off the coast of the Italian island of Giglio - with more than 4000 passengers and crew were on board.
32 people died in the accident - and the bodies of two victims were never found.
Survivor Luciano Castro returned to the island to witness the operation.
SOUNDBITE: (Italian) CONCORDIA SURVIVOR LUCIANO CASTRO, SAYING:
"Naturally, I think of those people who didn't make it and especially for those two families who are still waiting to find the remains of their loved ones, they must still be under the keel of the Concordia and I hope, after this, finally they will have a grave over which they can cry."
The so-called "parbuckling" operation to right the ship was originally scheduled to take about 12 hours.
But, officials who declined to estimate how much longer the operation would take - said crews could be working well into the night.
