HROV

Hybrid ROV for coastal applications

The H-ROV is an underwater vehicle, powered by on-board Li-on batteries, which can be deployed in both teleoperated mode (ROV) and autonomous mode (AUV), for coastal applications (up to 2500m) and from small vessels without dynamic positioning.

Missions

  • Acoustic cartography
  • Local inspection very close to the sea floor
  • High resolution & geo-referenced optical imaging
  • Samples collecting
  • Light tools manipulating
  • Ability to work on steep slopes

Concept

The Hybrid ROV is powered by on-board batteries that reduces the weight and volume of on-deck equipment. It can beoperated in:

• teleoperated mode (ROV), via a light optic fibre cable deployed from a depressor or a cage. This tether management system allows the vehicle to operate from vessels without dynamic positioning.

• autonomous mode (AUV), with an optional acoustic communication link.
