What is it for?

Ifremer has a modern fleet, under French flag, and all the necessary underwater equipment and know-how to conduct successful underwater intervention down to 6000 metres depth.

These means allow the location, the identification and the salvage of inert objects or equipment.

How it works?

These means are:

  • For the location: the vessels of the Ifremer fleet are equipped with multibeam echosounders for shallow and deep waters and can operate towed side scan sonars, such as the SAR. These equipment are combined with most up-to-date positioning systems.
  • For the identification and the inspection: mainly the manned submersible Nautile and the Remotely Operated Vehicle Victor 6000.
  • For the salvage: these vehicles are equipped with telemanipulator arms operating many tools adapted to the most difficult recoveries of inert objects. Basket systems or light density fluid bags allow to recover objects from 50 kg to several tons.
  • Vessels and vehicles crew is French.

Key innovation

  • The manned submersible Nautile allows a direct vision of the objects laying on the seabed and an immediate intervention thanks to the highly qualified pilot.
  • The Remotely Operated Vehicle Victor 6000 send images from the seabed in real time and allow also the intervention and recovery of objects selected by the customers.

Key achievements
