Lisbon, 21 October, 2019: The first WindFloat Atlantic platform with the turbine fully installed has set off from the Spanish Port of Ferrol towards its final destination 20 km off the coast of Viana do Castelo in Portugal. Once at the final location, the three floating structures –stretching 30 metres in height and with a distance between each one of their columns of 50 metres – will be installed to form the first floating wind farm in continental Europe.

The structure that has set off from the outer harbour of Ferrol comprises a floating platform and a wind turbine, the largest installed on a surface of these characteristics to date. In the coming months, two other platforms will be added to complete the windfarm which, with its 25MW installed capacity, will be able to generate enough energy to supply the equivalent of 60,000 users each year.

The project is led by the Windplus consortium, comprising EDP Renewables
(54.4%), Engie (25%), Repsol (19.4%) and Principle Power Inc. (1.2%). The facility
has three wind turbines mounted on floating platforms which are anchored only
with chains to the seabed at a depth of 100 m. It includes cutting-edge technology
that minimises the environmental impact and facilitates access to untapped wind
resources in deep waters. This technology has wide-reaching benefits that enhance
its accessibility and cost-effectiveness, including its aptness for dry-dock assembly
and towing without the need for specialised towing craft, or the advantages of not
having to rely on complex offshore operations associated with the installation of
traditional bottom-fixed structures.

WindFloat Atlantic project builds on the success of the WindFloat1 prototype,
which was in operations between 2011 and 2016. The 2MW prototype successfully
generated energy uninterruptedly over five years, surviving extreme weather
conditions, including waves up to 17 metres tall and 60-knot winds, completely
unscathed.

The transport alone of the first of the three floating structures making up the
floating wind farm at Viana do Castelo marks a milestone in itself, as it sidesteps
the need for towing craft designed specifically for this process. This benefit,
alongside the simple mooring process, make it possible to replicate this initiative
in other geographical areas and facilitates the commissioning phase regardless of
geographical boundaries.

The WindFloat can also support the world’s largest commercially available wind
turbines on a floating structure of almost 9 MW each, helping to increase power
generation and drive significant reductions in lifecycle costs.

The platforms have been built in cooperation between the two countries on the
Iberian peninsula: two of the platforms were manufactured at the Setúbal
shipyards (Portugal), and the third at Avilés and Ferrol shipyards (Spain). The
project uses WindFloat disruptive technology, which enables wind platforms to be
installed in deep waters, inaccessible to date, where abundant wind resources can
be harnessed.

This initiative has had the support of public and private institutions, encouraging
companies that are leaders in their respective markets to take part in the project;
while the Government of Portugal, the European Commission and the European
Investment Bank have provided financial support.

The partners that have made this project possible include Principle Power, the joint
venture between Navantia/Windar, the A- Silva Matos Group, Bourbon, the wind
turbine supplier MHI Vestas and dynamic cable supplier JDR Cables.
