Costa Concordia’s near $1-billion parbuckling (i.e. righting the ship) is set for a go on Monday, depending on weather and sea conditions, according to Italian authorities.

“The first date useful for the rotation of the Concordia is fixed at six o’clock in the morning of Monday, September 16,” read a statement. “However, weather conditions have to be favorable. The final decision about the beginning of operations will be therefore communicated by 2 pm of the previous day.”

The salvage consortium has been at work for over a year putting in various platforms and compartments to essentially provide a base and support to eventually rotate the ship upright.

That rotation may start as soon as Monday as the preparation work is done and Italian authorities have given it a green light.

The process could take all day, and the local waterways will be closed to traffic, and a no-fly zone will in addition be ordered.
