Abstract

To provide a recovery device for underwater vessel capable of easily recovering an underwater vessel by a small scale towing device, the towing device, a recovery system for the underwater vessel, and a recovery method for the underwater vessel.SOLUTION: When an underwater vessel 1 is recovered: a recovery device 50 provided with a structure 52 towed in a state of floating on the water surface by separating a floating body 1B from a body unit 1A of the underwater vessel 1 and having the floating body unit 1B floated on the water surface in a state of having the floating body 1B and the body unit 1A connected by a cable 1C and a connecting mechanism 51 for connecting the structure body 52 to a towing device 20, is towed by the towing device 20; the underwater vessel 1 is captured by hooking the cable body 1C or the floating unit 1B of the underwater vessel 1 to a capture unit 53 of the structure 52; and towing the recovery device 50 to a recovery target water area in a state of having the underwater vessel 1 captured in the capture unit 53 of the structure 52.SELECTED DRAWING: Figure 1
