The underwater robot is able to work 15 days and cover 1,100 square kilometers without assistance

The Norwegian company Kongsberg Maritime has reported that the new version of its Autonomous Underwater Vehicle (AUV), called HUGIN Endurance, can carry out surveillance missions of up to fifteen days offshore.

This high level of autonomy allows the AUV to operate without a mother ship to support it and travel from coast to coast, further reducing the so-called carbon footprint that results from using additional ships. The HUGIN Endurance has received communication equipment of the Maritime Broadband Radio (MBR) type so that the robotic vehicle can transmit large amounts of data when it appears. These are sent by radio to a ship, land station or even an offshore wind turbine on which an antenna has been installed.

Defense applications are broad, ranging from mine detection, classification and identification, to patrol missions in submarine transit areas, to others that require long periods of use where the AUV is left unattended. The civil applications are mainly focused on mapping large areas for the hydrocarbon industry or the installation of offshore wind turbines.

The HUGIN Endurance can be equipped with different sensors depending on the type of mission, e.g. B. Kongsberg’s own HiSAS sonar with synthetic aperture, a broadband multi-beam echo sounder, soil profilers and magnetometers as well as other sensors for the detection of parameters such as methane, properties of currents or turbidity of the water.
