FIELD: ship raising and rescue operations; raising surface ships, submarines and other large objects from deep depths.
SUBSTANCE: proposed method of raising sunken object consists in connecting this object with hoisting gear of rescue ship by means of elastic couplings followed by veering-in said couplings till sunken object has been surfaced. Rescue ship is made in form of catamaran with winches mounted on each hull; winches are driven by hydraulic turbine drive provided with hydraulic pump with shut-off and adjusting fittings. Winches are smoothly distributed along each hull of catamaran; flexible couplings connecting the winches with sunken object are passed through inner sides by means of blocks. Total number of winches and flexible couplings is equal to quotient of force required for raising the sunken object and limiting cargo hoisting capacity of separate flexible coupling.
EFFECT: avoidance of bending forces in hull of object being raised.
