Now, however, many green energy companies are looking toward a new kind of offshore wind turbine that won't need a concrete foundation. This new technology allows a turbine to float instead of sitting on the ocean floor.
Researchers from the University of Sao Paulo are focusing on several aspects of modeling and analysis of offshore wind turbines.
University of Texas at Dallas researcher Dr. Todd Griffith has spent years working on an offshore turbine design that can convert those deep-ocean winds into electricity. Recently, Griffith received a $3.3 million grant from the U.S. Department of Energy to take his technology to the next level.
It is the first of three ABS-classed, SEMI Submersible Type units designed by Principle Power housing MHI Vestas turbines that will make up for a total of 25 MWs of floating offshore wind power.
The world's largest floating offshore wind power plant, Hywind Tampen, will be located in Norway, with a total capacity of 88 MW and equipped with 11 SG 8.0-167 DD turbines.
The turbine's two prototype nacelles, weighing several hundred tonnes, required transportation on site, while separately the yokes that position each blade during installation required load testing to ensure they could withstand the required load.
The projects selected today are expected to begin offshore construction in late 2022 and be completed by 2024.
With offshore wind farms like Merkur expected to generate energy over an operating life of 25 years, operation and maintenance typically accounts for 15-25 percent of their total lifecycle cost.
Annual market report shows a healthy wind industry delivered record US jobs, $1 billion in rural community and state payments last year
"As the costs of offshore wind are declining, the U.S. offshore wind industry is quickly advancing with strong Federal and State support. The industry is well-positioned to meaningfully contribute to the New York and New Jersey economies through employment and supply chain
Via ScienceDaily: New research reveals an unexpected benefit of large-scale offshore wind farms: the ability to lessen precipitation from hurricanes.
U.S. wind farms surpass 90 GW with strong demand from Fortune 500 brands and utilities
Featuring a 12 MW direct drive generator and an industry leading gross capacity factor of 63 percent, the Haliade-X will produce 45 percent more energy than any other offshore turbine available today.
Peter Levring for Bloomberg Technology: Denmark obtained 43.4 percent of its electricity from wind last year, beating its own record. The governments goal is to derive 50 percent of the countrys entire energy consumption from renewables by 2030.
Lorraine Chow for EcoWatch: The vision is so massive that the developers will have to construct a 2.3-square-mile artificial island in the North Sea to support the 10,000-turbine complex.
