For the purposes of the safe removal of the Costa Concordia wreck, SOIL Srl has been involved into all aspects concerning the geological and geotechnical design and assistance for the construction of the foundation structures.

The Costa Concordia Wreck Removal Project foresaw in the first stage the rotation of the wreck to its vertical position (parbuckling phase) and subsequently its re-floating by means of the installation of steel caissons on both sides of the ship.

The parbuckling required the construction of underwater anchoring structures on the landward side of wreck and the installation of three submerged platforms for its temporary support in vertical position on the seaward side. The structures were built respectively at water depths of 5 ÷ 10 m and 40 ÷ 50 m below sea level. Drilled steel piles (D = 2 m) were designed for the platforms foundations.
