With its internal long endurance battery the HROV is a self-propelled underwater vehicle which can be used as a Remotely Operated Vehicle, ROV, as well as an Autonomous Underwater Vehicle, AUV.
Equipped with high resolution sensors and powerful electrical arms the HROV can be used for survey, inspection or intervention in depth down to 2500 m.
