New wave of wind energy
13 Dec 2012

The temporary 1:8 scale wind turbine test site was installed Nov. 29 and will be in place for up to three months. Following a successful test, UMaine's patent-pending VolturnUS test prototype will be placed off the coast of Maine in two locations in 2013.

Components of the floating turbine are being manufactured at the UMaine's Advanced Structures and Composites Center, and will be shipped to Cianbro's facility in Brewer, where the unit will be assembled including hull, tower, turbine and blades, and placed in the Penobscot River in a vertical position. The floating turbine unit will be towed down the river and moored at sea for testing to evaluate the technology and environmental impacts, and to collect data to validate design tools.

Once in the Gulf of Maine, the turbine will be the first grid-connected offshore turbine in the United States, marking a critical milestone for the development of floating turbine technology. The demo project is designed to de-risk the technology and pave the way for private investment in a commercial scale-park by 2018-20, according to Habib Dagher, director of UMaine's Advanced Structures and Composites Center. The technology was tested in a wave-wind basin at the 1:50 scale in 2011.

Following a successful offshore test next year, a small 12 MW demonstration project consisting of two, 6 MW turbines is proposed for construction in 2015-17. A commercial-scale park, expected to be in the 500 MW range, will have more than 80 turbines in a space of 4 miles by 8 miles, and will be positioned more than 20 miles off shore, beyond the horizon. "We're here at the beginning of an exciting era that could create a whole new industry in our state, and reduce our reliance on imported fuels", says Dagher.

UMaine President Paul Ferguson notes that the work of the Advanced Structures and Composites Center features a remarkable blend of student and faculty researchers, as well as public and private partners who characterize the University of Maine as a leading 21st-century research university. "The center is poised to lead the transformation in deepwater offshore wind research", Ferguson says.

The deepwater offshore wind research is a key transformative technology that the U.S, needs in order to compete globally, says Sen. Susan Collins, who has been instrumental in helping secure critical federal seed funding to advance the project's R&D efforts.

"Maine has been at the forefront of deepwater floating turbine technology, and I am confident Maine will be at the forefront of making deepwater offshore wind a hallmark of U.S, innovation", Collins says. "The Advanced Structures and Composites Center is developing cutting-edge research, providing an outstanding education for the next generation of engineers, and, best of all, spurring economic growth for our state and new jobs for our people".

UMaine formed the DeepCwind Consortium with more than 30 commercial partners in Maine and beyond who are collectively working on prototype floating wind turbines. The Maine Ocean Energy Task Force has set a goal of producing 5 gigawatts of offshore wind by 2030. Building this 5 gigawatt network of floating offshore farms could attract nearly $20 billion of private investment to Maine and potentially create thousands of jobs, according to Dagher.

Obama's energy policy is right. Japan's FiT in July is among the highest in the world. Japan's FiT is shaking the renewable energy market. New solutions will be showed in Japan. This is it!
Floating Wind Turbine is one of the best solutions for USA and UK. U.K has more install places around its shores than any other in the world. USA has Atlantic Coast. As you know, Every year Some typhoons arrive Japan. The typhoon has strong wind. Floating Wind Turbines must have constructed to resist typhoons. So they have to reduce vibration to install Floating Wind Turbines on the sea. Because, it makes many kinds of problems! Vibration’s caused by wind, waves and external forces. New Floating Body Stabilizer for Floating Wind Turbines has been created in South Korea. The Floating Body Stabilizers generate drag force immediately when Floating Wind Turbines are being rolled and pitched on the water. Recently, this Floating Body Stabilizers have been used to reduce vibration of Floating Solar Panels in South Korea. You can see New Floating Body Stabilizer videos in YouTube.,
