Costa Concordia

The recovery concept for the ship Costa Concordia, which sank off the coast of the island of Giglio in January 2012, involves upright positioning using leverage applied through bundle strands and hydraulic presses. The resulting deflection forces are safely re-anchored into the existing rock on the side between the ship and the coast through underwater cast foundation blocks using SAS injection anchors of the SAS 670/800 grade. For this project, the planners of the salvage company and our client Trevi S.p.A, together with the research and development department of SAH, developed a project-specific special solution, which was quickly implemented in collaboration with our Italian subsidiary SASITA s.r.l. The SAS threaded bars were factory-equipped with PE piping in the area of the free length. The annular space was subsequently pre-injected with corrosion protection material at the factory to ensure both the free elongation of the threaded bar during the stressing process and the corrosion protection of the system. This enabled us to provide the client with a ready-to-install solution without the need for time-consuming assembly work on the confined construction site.
