Default World's biggest submersible to remove Concordia

World's biggest submersible hired to remove Costa Concordia from Giglio

The world’s largest heavy lifting ship may be used to remove the Costa Concordia from the island of Giglio, where it capsized in January 2012.

The flat-shaped transport ship "Dockwise Vanguard," developed for moving oil platforms, works by submerging its middle section so heavy loads can be placed on top of it Photo: AP

That would be pretty cool to see, just as it was when they uplifted it...I did hear it will be sometime next year before it can finally be removed??

Default The Costa Concordia Removal Operation is a Wrong Approach

The Costa Concordia par-buckling Operation is a Wrong Approach
I think the idea of moving the wreck of Costa Concordia to upright position
is not the best solution. It is time-consuming and materials-consuming and
it is by far more expensive.

It would have been better to float and tow it in its tilted position because
keeping a damaged ship upright after shifting and distorting its center of
gravity and after its bottom cavity was destroyed is clearly huge task.
We must notice that almost one quarter of its left side is crushed

I suggest a much easier and cheaper approach, as follows:
1. Make many small light weight tanks
2. Sink equal numbers of these tanks on both sides along the length of the wreck
3. Tie each tank with at least three tanks on the opposite side of the wreck with steel cables passing underneath the wreck
4. Tighten the mesh of steel cables to bring the opposite tanks as close as possible
5. Start pumping the water out of the air-tight tanks simultaneously to make them float and lift the wreck
6. Add more connected tanks as much as needed on both sides of the wreck to raise the load substantially
7. While it is afloat and still on its tilted position it is possible to tow the wreck away to a ship dismantling yard
