The project, called Hywind, is the world's first large-scale deepwater wind turbine. Although it uses a fairly standard 152-ton, 2.3-megawatt turbine, Hywind represents "totally new technology," says Walter Musial, the principal engineer for ocean renewable energy at the National Renewable Energy Laboratory of the U.S. Department of Energy. The turbine will be mounted 213 feet above the water on a floating platform, or spar — a technology Hywind's creator, the Norwegian company StatoilHydro, draws from its experience as Scandinavia's largest gas and oil company. The steel spar, which is filled with ballast and extends 328 feet below the sea surface, will be tethered to the ocean floor by three cables; these will stabilize the platform and prevent the turbine from bobbing excessively in the waves. Hywind's stability in the turbulent, wintry Scandinavian sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start generating electricity six miles off the coast of southwestern Norway as early as September.
