BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for lifting a sunken ship,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for lifting a sunken ship, and more particularly, to a method of lifting a ship by floating the ship on a water surface after buoyancy is applied to the ship, .

It is stored in the water of a shipwreck caused by the stranding of a ship or a marine accidents, causing severe problems such as pollution of the ocean or loss of property.

Korean Patent Application No. 1999-0014304 "Ship sinking device ", No. 2004-0033228" Ship equipped with sinking prevention device "and the like are disclosed to prevent or prevent sinking, It has the purpose of providing buoyancy to the hull to prevent sinking.

However, these known examples are applied only to the hull before the sinking, and there arises a problem that a separate method should be applied to the hull after the sinking.

As another known example, air is directly injected into a sunken cargo hold or compartment, and buoyancy is generated to float the sunken ship.

However, the direct air injection method as described above has to close the openings such as the cargo hold, and it is impossible to precisely seal the openings, so that the inflated compressed air needs to be supplied indefinitely.

As another known example, a large crane can be used for lifting. Large cranes have to withstand large loads during lifting, so it is difficult to equalize the environment immediately and there is a risk of accidents.

In addition, there is a problem that the boat is cut or partially damaged due to the hoisting string wound around the sunken hull.
