LEDI Subsea Drilling® MSC Napoli

In order to be able to install the twelve lifting chains, the wreck was drilled through and for the first time this will be done with a drilling installation placed on the seabed, which is a revolution in salvaging shipwrecks. In a first salvage operation, all containers were unloaded from the ship and bunkers were removed. The bow has also been towed away for scrapping. The remaining wreckage has an estimated total weight of 3.800 tons. The intention was to demolish the stern, with a lenght of approximately 65 m and a width of 36 m, on site. In order to dismantle the stern of the MSC Napoli, the wreckage must be lifted. To this end, drilling is being carried out underneath the shipwreck to install twelve lifting chains. Pontoons, each equipped with twelve specially designed winches (chain pulling machines), are moored parallel to both sides of the wreck. The cranes on both pontoons will then lift the demolished wreckage and place them on the pontoons where they can be cut into smaller sections.
