World first concrete composite floating wind turbine deployed in US

Turbine platform deployed off Maine coast is first grid-connected offshore floating wind turbine prototype for US

Maine University is leading the project. The university is also working on one of a series of offshore wind projects announced by the Energy Department last year

The world's first concrete composite floating platform wind turbine has been deployed in the US. The US Energy Department has recognised the nation's first grid-connected offshore floating wind turbine prototype off the coast of Castine, Maine, which is the first of its kind in the world.

Led by the University of Maine, the project represents the first concrete composite floating platform wind turbine to be deployed in the world. The Energy Department said the development strengthens American leadership in innovative clean energy technologies.

Jose Zayas, director of the Energy Department's wind and water power technologies office, said: "Developing America's vast renewable energy resources is an important part of the Energy Department's all-of-the-above strategy to pave the way to a cleaner and more diverse domestic energy portfolio.

"The Castine offshore wind project represents a critical investment to ensure America leads in this fast-growing global industry, helping to bring tremendous untapped energy resources to market and create new jobs across the country," said Zayas

With the support of a USD 12m Energy Department investment over five years, the University of Maine and its project partners conducted extensive design, engineering and testing of floating offshore wind turbines, followed by the construction and deployment of its 65ft-tall VolturnUS prototype. At 1:8th the scale of a commercial installation, this project will collect data to validate and improve floating wind turbine designs, while helping to address technical barriers to greater offshore wind cost reductions.
