New energies

With over 40 years of expertise in offshore work and projects, Geocean is your partner in deploying offshore solutions for marine renewable energies (MRE).

Geocean develops and accounts for the carbon footprint of all our projects to make them as environmentally friendly as possible and to work towards the 2030 and 2050 targets set by the VINCI Group.

Currents sea energy

It uses the movement of seawater generated by natural marine currents to drive turbines.

Sea energy

It harnesses the energy of rising and falling tides. Tidal dams or underwater turbines can convert this energy into electricity.

Waves energy

It converts the kinetic energy of waves into electricity using various floating devices or devices fixed to the seabed.

Sea thermal energy

It exploits the difference in temperature between surface seawater, heated by the sun, and cold deep-sea water to produce electricity.

Offshore energy

Thanks to our experience in offshore projects and the installation of anchoring systems, we are already positioned as a strong player in the emerging floating wind market.
