A collaboration on floating wind technology has been signed between France’s Naval Energies and Japan’s Hitachi Zosen Corporation.

The two companies will design and build floating wind turbines with a capacity of several hundred megawatts off the Japanese coast using Naval Energies’ semi-submersible floating solution, which is a concrete, steel or a hybrid combination fixed to the seabed by an anchoring system that controls its movements.

Naval Energies says that compared to traditional fixed-foundation wind turbines, the technology “overcomes the constraints of deep-water installation and is able to produce renewable energy farther from the coast with a low visual impact”.

Takashi Fujita, windpower general manager at Hitachi Zosen, said: “Among all floaters developed in the world, we consider that Naval Energies’ semi-submersible is one of the best on the market.”

Naval Energies president Laurent Schneider-Maunoury said: “The environmental conditions in Japan are very favourable for the installation of this technology and we have all the necessary know-how for the local development of this new industrial sector. We hope that this step is the first of a long-lasting and fruitful collaboration between our two companies.”

The deal between the companies was signed during a visit to Japan by French President Emmanuel Macron and Minister of Economy and Finance Bruno Lemaire.
