The invention discloses a steel
wire rope splicing device and method for deepwater salvage, and relates to the technical field of salvage and salvage of offshore sunken ships, the steel
wire rope splicing device comprises a sunken ship, a crane ship and a crane installed on a
deck of the crane ship, a
stern side jack is arranged at the
stern of the
deck of the crane ship, and a bow side jack is arranged at the bow of the
deck; a 80t anchor gear is arranged at one end of the
stern side jack, and a wave compensator is arranged at the other end of the stern side jack; one end of the bow side jack is provided with a
rope container used for storing bow side steel wire ropes, the crane is provided with two main hook steel wire ropes, each main hook steel
wire rope is provided with a triangular plate, the main hook steel wire ropes are spliced or disassembled through the bow side steel wire ropes and a second steel wire
rope, and the triangular plates can achieve switching of lifting force when the steel wire ropes are spliced; the stern side jack is used for bearing ship sinking acting force when the steel wire
rope is spliced or detached; the ship bow side jack plays a role in temporarily fixing the steel wire rope B in
