Project description

Floating turbines could unlock the full potential of offshore wind energy

Offshore wind is a highly promising renewable energy source that could make a major contribution to European and global efforts to decarbonise the economy by 2050. Where bottom-fixed foundations can only be installed in shallow water depths of around 40 m, floating foundations allow access to deeper waters. Recognising that a great part of the ocean’s resource potential lies in deep waters, the EU-funded LEADFLOAT project is developing a floating offshore wind platform. The platform will be extremely compact and simple, and compatible with existing and future extra-large wind turbines. The consortium is also exploring the possibility of using concrete or steel for its construction.


Offshore wind has emerged as a highly effective, cost competitive and a key contributor to the European energy transition challenge.
Yet, current technologies limit offshore wind deployment to shallow water depth (less than 40m) restricting the market potential to a few countries (mainly the North Sea), while the vast majority and the best wind resources are located in deep waters. The installation of wind turbines on floating foundations inevitably appears as the future of offshore wind. Floating foundation solutions unleashes the market potential with no restriction on the water depth or on the seabed soil conditions, allowing developing projects further offshore where wind is stronger and the visual impact is limited.
IDEOL, a French SME created in 2010, has emerged as one of the few international leaders in floating wind, with two demonstrators built in France and Japan, relying on its patented floating platform technology, the most cost competitive solution in the market. Its team, composed by more than 40 engineers, is globally recognized as one of the best technical team with a unique know-how and innovative approach. IDEOL is already engaged in different pre-commercial and commercial projects in France, Japan and California. It is the only European technology provider and the only foreign company having convinced the Japanese government and experts.
Its technology is characterized by its extreme compactness and simplicity, its compatibility with the existing and the future extra-large wind turbines without modification, its construction either in concrete or in steel.
LEADFLOAT aims to impose IDEOL’s solution as the market leader of floating wind by keeping its cost competitiveness advantage, leveraging on its demonstrators’ return of experience and securing early market share in key markets. It will contribute to keep Europe ahead and to positions its industry on the top of the new emerging floating-wind market over the competition from US and Japan.
