First floating wind farm in continental Europe is now fully operational
The last platform of WindFloat Atlantic has been connected to the grid, and the windfarm has been fully commissioned.
With a total installed capacity of 25 MW, WindFloat Atlantic is the world’s first semi-submersible floating wind farm.
WindFloat Atlantic is now fully operational and supplying clean energy to Portugal's electrical grid. Following the connection of the last of the three platforms to the 20 km export cable connecting the wind farm to the substation at Viana do Castelo, Portugal, the construction of the wind farm is now complete. WindFloat Atlantic, which has a total installed capacity of 25 MW, is the world’s first semi-submersible floating wind farm, and it will generate enough energy to supply the equivalent of 60,000 users per year, saving almost 1.1 million tons of CO2.
This milestone cements the success of a decade-long project by the Windplus joint venture, ensuring access to the best wind resources in water depths that have previously been inaccessible. Windplus* has successfully installed and connected three platforms - measuring 30 m in height with a 50 m distance between columns. Each is able to accommodate an 8.4 MW turbine, the largest ever installed on a floating platform.
The success of this project is rooted in its technology. Its mooring technology, for example, allows for installation in waters over 100 m deep, and its design offers stability in adverse weather and sea conditions. Another key advantage has been the assembly technology used: dry-dock assembly has provided significant logistical and financial savings, and the platforms have been towed using standard tug boats.
These technical advantages, among others, clearly show that Windfloat Atlantic's model is replicable in other areas where adverse seabed conditions or significant water depth mean that traditional bottom-fixed offshore wind technology is not an option.
