    1/50 scale model tests have proven that our floater is able to withstand with both harsh seastates and misaligned wind-wave conditions.

    Many thanks to IFREMER, France Energies Marines and Agence Nationale de la Recherche.

    A floating wind farm of 300 x 50 km produces as much as the whole 58 french nuclear power plants !

    Using a single point mooring reduces cost of energy : installation and maintenance operations are simplified while park's availibility is better

Market

Energy transition is already going on in Europe : Germany plans to get 90% of renewable penetration by 2050 while in 2015, 9% of UK's electricity came from wind and half of it from offshore wind.

#

On the contrary of conventional fixed offshore wind, floating wind parks are compliant with sea depth greater than 50 meters (blue and pink areas on the picture below).

#

A wind park of 300km long and 50 km width produces 400 Twh each year : same value as the 58 french nuclear powerplants.


Worlwide potential is 10 000 TWh/y while France Energie Eolienne evaluates french potential to 400 TWh/y.

A breakthrough concept

  • A patented structure which offers a better stress distribution and no vibrations issues. This leads to less fatigue damage and less structure's Capital Expenditure.

#

  • A patented floating wind turbine which deploys a single point mooring. This simplifies installation and maintenance because power cables and mooring lines are installed independantly from the wind turbines.
  • Innovative control strategies able to reduce fatigue damage and floater's size.


Cost of energy

Onshore wind is already competitive but a massive implantation in Europe seems difficult because of population density.

Offshore wind cost are decreasing, and 103€/MWh has been recently achieved in Denmark (2017 update : 76 and 64€/MWh in Netherlands and Denmark !)

#

Considering that Europe have very small fossil resources,

Considering nuclear power has underestimated both major disaster probability and dismantling cost,

Massive floating wind parks will be part of a renewable energy mix in the next decades. Massive means scale economy.

In this economical context, the whole EOLINK design is optimized to get best-in-class cost of energy :

  • EOLINK concept increases Annual Energy Production thanks to a high availability rate using redundant systems (multiphased synchroous direct drive generator, twin-pitch system, plug-in electric layout).
  • EOLINK decreases Wind Farm Capital Expenditure thanks to its structure which easily sustains bigger rotors and nacelles (>10 MW generator, rotor > 200m).
  • EOLINK also cuts down Capital Expenditure reducing loads and stresses and thus using less materials for the structure (-30% of steel at iso-power and iso-control strategies).
  • EOLINK doesn't require huge cranes or expensive vessels for both installation and maintenance. EOLINK wind farms are also designed for very low down-times : reduced Operational Expenditure costs.

Computed LCOE benefits are higher than 25% compared with a reference 6MW SPAR.
