FIELD: transport.
SUBSTANCE: invention relates to ship lifting and rescue operations. Proposed complex comprises two self-propelled derrick boats furnished with load handling appliances with grippers. The latter comprises frame with rotary driven lugs that can embrace sunken ship without squeezing it. Note here that gripper can vary lengthwise and crosswise gripping angles to rule out suction of hull to bottom. Ship lifted to self-propelled derrick boats, bow and stern adapters-fairings and bottom adapters are attached to form self-propelled floating drydock.
EFFECT: possibility to lift sunken ships from various depth and safe transportation.
