The Design Basis of Naval Energies’ floaters, applicable to the Groix & Belle-Ile wind farm, and calculation and design methods applicable to its floaters in general are certified by DNV GL, a world-class certification body involved in renewable energies and specifically in offshore wind energy.

Obtaining this demanding certification demonstrates that Naval Energies’ calculation and design methods are applicable to the company’s semi-submersible floater technology, and aligned with the standards and recommended practices of DNV GL in terms of floating wind turbines. The detailed assessment carried out by DNV GL experts focused on the overall calculation methods related to hydrodynamics, structure, anchoring and tank test campaigns. It resulted in the approval, documented in a certification report, of the calculation and design methods applicable to Naval Energies’ semi-submersible floater. This certification shows that Naval Energies’ calculation and design methods are applicable for the company’s current and future floating wind turbine projects.

In fact, Naval Energies’ floater for offshore wind turbines was awarded the Solar Impulse Efficient Solution label following an evaluation carried out by independent external experts and based on verified standards. The Naval Energies floater thus joins the #1000solutions challenge, an initiative of the Solar Impulse Foundation to select solutions that meet high standards in terms of profitability and sustainability, and to present them to decision-makers in order to speed up their implementation. Three criteria are taken into account to obtain this label: the solution’s technological feasibility, its profitability, and the environmental and socio-economic benefits it provides.
