Globally Validated Floating Offshore Wind Technology and Operational Experience

KF Wind is committed to the successful execution of its Ulsan project using globally validated floating offshore wind technology, with expertise coming from its shareholders.

Ocean Winds, the majority shareholder of KF Wind, is currently advancing 17 offshore wind power projects across eight countries, including France, the United States, Belgium, Australia, Poland, Portugal and the United Kingdom, with a third of this portfolio being floating offshore wind technology. Drawing on more than 15 years of experience, from the WindFloat1 prototype to today’s successful five years of operations of WindFloat Atlantic and the current construction of the EFGL project, Ocean Winds is a pioneer in floating offshore wind and applies its experience to its commercial scale floating offshore wind energy projects, currently under development, including KF Wind.

WindFloat 1 Demonstration Project, 2011-2026
Ocean Winds’ track record and experience with floating technology traces back to the WindFloat 1 demonstration project launched in Portugal in 2011. It combined a semi-submersible floating platform with a 2MW floating wind turbine. Operated off the coast of Portugal for five years, the project generated and supplied approximately 17 GWh of electricity to the surrounding region before being decommissioned in 2016.

WindFloat Atlantic, In Operation since 2020
The WindFloat Atlantic floating offshore wind farm, with a capacity of approximately 25MW, consists of three semi-submersible floating platforms and three 8.4MW turbines. It has been in operation since 2020, located about 20 kilometers off the coast of Viana do Castelo, Portugal, in waters around 100 meters deep.

This is the world’s first semi-submersible floating wind, that has been supplying clean, renewable energy to 25,000 Portuguese households annually since 2020.

EFGL, 2025
The EFGL floating offshore wind project, currently under construction off the coast of Leucate, France, has an installed capacity of 30MW and consists of three 10MW turbines, the most powerful ever to be installed in France. It features a new generation of WindFloat semi-submersible floating platform technology. This project marks the first instance of a floating wind farm being built within a marine protected area—the Gulf of Lion Natural Park—where environmental preservation is a top priority. EFGL is currently under construction at the Port of Port La Nouvelle, with the first turbine assembly celebrated in June 2025, and offshore installation scheduled for the summer 2025.

Developed in close collaboration with local stakeholders, EFGL will deliver valuable technical, operational and environmental insights to inform the next generation of floating offshore wind farms in the Mediterranean, including Ocean Winds’ EFLO (Eoliennes Flottantes d’Occitanie) 250 MW floating offshore wind project, currently in its early stage of development.

KF Wind

KF Wind is backed by years of technological advancement and operational experience of its shareholders, KF Wind’s solutions offer the following key strengths:

High Power Output : KF Wind’s technology is designed with next-generation innovations that enable power generation in deeper waters, catching the wind where it is the strongest. Thanks to its offshore-specific foundations and stronger wind offshore, larger-capacity wind turbines can be installed, allowing greater volumes of renewable energy to be supplied to the Ulsan region.

Exceptional Stability : The floating platforms are equipped with water ballast systems and heave plates positioned at the base of each column, enhancing stability against extreme weather conditions. These features help the structure withstand lateral forces from winds up to 55 knots and waves up to 60 knots.

Deepwater Solution : KF Wind’s technology enables installation more than 200 meters from the shoreline and mooring in water depths ranging from 70 meters to as deep as 1,000 meters—making it adaptable to a wide range of offshore environments.
