Ikhtisar

Norwegian 8 m diesel survey USV built for hydroacoustic work, AUV support, and fishery research.

Sounder is Kongsberg's 8 m uncrewed surface vessel for hydroacoustic missions. A 125 hp diesel engine gives a 12-knot top speed and about ten days of endurance at a 4-knot survey speed, while delivering more than 4 kW of power to the payload. Sensors can be fitted in a moonpool, at the bow, or in the hull, so the same craft can carry multibeam echosounders for hydrography, USBL transducers to track and aid HUGIN AUVs, fishery sonars and scientific echosounders, or a CTD winch. Kongsberg's K-MATE autonomy engine supports direct, supervised, and fully autonomous operation over broadband radio and Iridium. The boat ships in a standard container with a folding mast, and its operators include survey contractors and Aker BioMarine for Southern Ocean krill surveys.
