METHOD OF RESCUE OF CREW FROM SUNKEN SHIP AND HOISTING AND TOWING THIS SHIP Russian patent published in 2004 - IPC

FIELD: methods of rescue of crews from sunken ships.

SUBSTANCE: proposed method includes positioning the submarine above sunken ship, coupling them together by means of towing ropes, making the crew to pass to submarine from sunken ship through hatches of this submarine, hoisting the sunken ship by means of submarine and joint towing of them to dock. Submarine is positioned above sunken ship on bottom ground located below submarine and connected with her sides by means of hood provided with aft gates and upper transversal ropes; then water is pumped out of hood at simultaneous delivery of atmospheric air to it over lines connecting the submarine with auxiliary ship. Crew passes to submarine by suspended ladders. Then, buoyancy of sunken ship is restored by draining water and repairing holes followed by filling the damaged compartments with foam-generating solution. Towing ropes are connected with fore and aft couplings of hood and lower transversal ropes are passed under sunken ship and are secured on hood couplings, after which hatches are closed, hood is filled with water and buoyancy is admitted to submarine.

EFFECT: enhanced efficiency of conducting rescue jobs.
