Device of salvage the sunken ship remains overturned towards the deck in the water

摘要

A method of lifting a ship hulled with a deck facing downward in water to solve the above problems, comprising the steps of: a) lifting a hull provided with a hull attachment portion, a connecting portion, and a pulling tow for covering the bottom side of the hull; A step of installing a towing portion and a hull rotating buoyancy body provided with a buoyant body connected to the attachment portion to the hull so as to supply air to the buoyant body of the hull rotating buoyancy body so that the deck faces the upper surface by buoyancy A step of rotating the hull, a step c of installing a reference lifting condition checking unit provided with a lifting condition detecting unit connected to the lifting condition attaching unit on the hull, d, and a lifting condition checking unit having the same configuration as the reference lifting condition checking unit Installing a hull lifting body having the same shape as that of the hull rotating buoyancy body; f) floating the hull by buoyancy by supplying air to the buoyant body of the hull lifting body, G, lifting the hull to the water surface while checking the height of the hull and the horizontal state of the hull through the lifting state sensing unit; The deck is turned upside down toward the lower surface of the ship, and the sunken ship is lifted.According to the present invention, it is possible to provide a method of lifting a ship hulled with a buoyant body, and the use of a buoyant body can naturally cope with a change in flow velocity.In addition, since a plurality of buoyant members are installed on the hull, it is possible to provide a method of lifting a sunken hull which is safe because it is dispersed, and which is easy to balance during the lifting process.;
