WindFloat deployed offshore in Portugal

All final assembly, installation and pre-commissioning of the wind turbine occurred on land in a controlled environment

Amsterdam, November 30, 2011 — Energias de Portugal and Principle Power, Inc. are pleased to announce the successful offshore deployment of a full-scale 2-MW WindFloat off the coast of Agucadoura, Portugal.

This installation represents the beginning of a new sector in the offshore wind industry and is the result of continued work by all WindPlus JV partners including: EDP, Principle Power, A. Silva Matos, Vestas Wind Systems A/S, InovCapital, and Fundo de Apoio a Inovacao. In addition over 60 other European vendors participated.

The project is the first offshore wind deployment worldwide which 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 offshore wind turbine in open Atlantic waters, and the first deployment of a semi-submersible structure supporting a multi-megawatt wind turbine.

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 350km 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.

Over the next few weeks a rigorous commissioning, testing and startup procedure will be completed. This will include trial operations and a phased ramp-up in power production to full capacity.
