Offshore Wind Turbine Completed Onshore, Towed Out To Sea

Energias de Portugal and Principle Power Inc. have announced the successful offshore deployment of a full-scale 2 MW WindFloat off the coast of Agucadoura, Portugal.

According to the companies, this represents the first offshore wind deployment worldwide that did not require the use of any heavy-lift equipment offshore. All final assembly, installation and pre-commissioning of the wind turbine occurred on land in a controlled environment.

Further, this is the first deployment of a semi-submersible structure supporting a multi-megawatt wind turbine, the companies say.

Following pre-commissioning of the system onshore at the Lisnave facility near Setubal, Portugal, the WindFloat was loaded-out using a dry-dock and towed offshore. The offshore tow consisted of some 350 km in open Atlantic waters. The ability to tow in such conditions is attributable to the same WindFloat stability performance that permits the use of off-the-shelf commercial wind turbines from any manufacturer.

The companies will now complete a commissioning, testing and start-up procedure, which will include a phased ramp-up in power production to full capacity.
