Abstract: The invention relates to a system and a method for recovering a submarine vehicle. The submarine vehicle is pulled by a rope and hauled by means of the rope and a recovery ramp from the body of water on board a ship or onto land. The system comprises the recovery ramp and a wave equalization ramp. The wave compensation ramp can be rotated relative to the recovery ramp about a swivel axis S and is supported by a floating body. The watercraft is picked up by means of the recovery ramp. The wave compensation ramp is hauled together with the picked-up submarine vehicle by means of the recovery ramp. The invention permits the recovery of a submarine vehicle, even in moderate or heavy seas, with less risk of damage to the submarine vehicle.
