the moment of truth would come between 10.00am-11.00am local time on Monday "when we raise the wreck and can compare our calculations and forecasts with actual data"
In the next phase of the operation, the Costa Concordia is to be moved 30 metres from the shoreline and held steady by two tugs and cables secured on land.
refloating the giant vessel and moving it into open waters would take "a week or, at best, five days".
If all goes well, the tugs will then tow it 200 nautical miles to Genoa, where it will be broken up.
Travelling at about two and a half knots, the Costa Concordia is expected to take another four to five days to complete the journey.
