SALVAGING DEVICE AND SALVAGING METHOD FOR SALVAGING CONDENSED MATTER LOCATED ON THE WATER SURFACE OF A WATERWAY

The invention relates to a salvaging device and a salvaging method for salvaging condensed matter, such as an underwater vehicle, located on the water surface of a waterway. The salvaging device is an unmanned watercraft and comprises a boat hull with a maneuvering means and with a carrier device as well as a salvaging receptacle fastened to the boat hull. The watercraft is maneuvered in a self-driven manner on the water surface and collects the condensed material into the salvaging receptacle where the collected matter is stored. A crane of a supply ship then lifts the salvaging device and stored condensed matter out of the waterway. The invention permits the salvaging of the condensed matter, e.g., an underwater vehicle, with a reduced risk of damage to the condensed matter, as well as with a reduced risk to personnel who do not need to enter the water for this purpose.
