Naval Energies’ design of its foundation for floating offshore wind turbines (FOWTs) has been certified by Bureau Veritas

15.06.2017

Bureau Veritas has issued a Preliminary Design Approval for a FOWT foundation designed by Naval Energies. This major step in the FOWTs development is validation for upcoming projects in France, the USA and beyond.

The floating foundation is based on a semi-submersible floater, designed to be competitive, adapted to mass production, easily towable, connectable and dis-connectable, and adaptable to site conditions & local industrial environments.

This approval was provided as part of the General Electric (ex-Alstom) and Naval Energies Sea Reed project, a FOWT product development initiative supported by ADEME, the French Environment and Energy Management Agency.

Thierry Kalanquin, Chief Executive Officer, Naval Energies, commented, ‘The approval by Bureau Veritas of our latest foundation design is a step forward towards the development of our global industrial and integrated FOWT solutions. This certification granted by an independent and reputable international certification agency proves the maturity and seriousness of our solution. It also validates our system in the short-term for our ongoing projects, in France and in the United States but also in the mid and long term for our future commercial farms projects all around the world.’

A Preliminary Design Approval for Bureau Veritas implies that the Basis of Design has been approved. The design is feasible, achievable, and contains no technological show-stoppers that may prevent the design from being matured. Bureau Veritas engineers verified design methodologies, covering hydrodynamics, structure, stability and electricity. They also checked that the design is deemed to be suitable for use in all phases of operation including in-transit to field, installation and commissioning as well as providing recommendations through subsequent phases of the project.

Matthieu de Tugny, COO, Senior Vice-President and Head of Offshore, Bureau Veritas, commented, ‘We are seeing increasing interest in FOWT technology as demand for wind power increases. FOWTs, fabricated onshore, can be installed in deep water and variable seafloor topographies. ’Because of their low environmental impact during installation and application in deeper waters, we can see that demand for FOWTs will grow. ‘

Cooperation between Bureau Veritas and Naval Energies in the floating offshore wind sector will continue to grow with floating wind project planned to be deployed between the Groix & Belle-Ile Islands. The array will comprise four 6MW GE Haliade turbines, installed on a hybrid version (steel & concrete) of Naval Energies floating foundations. Bureau Veritas has been awarded for the whole Project Certification of the floating wind array, covering the different project phases: site conditions assessment, design evaluation, manufacturing, transportation and commissioning surveillance. The units are expected to be operational in 2020.
