Model Test of Floating Wind Turbine

As environmental pollution and energy shortage have been serious all over the world, governments and organizations have been interested in developing renewable energies which do not release pollutants. Interest in wind energy of those has been higher and developed more than others. Because of insufficient space to install wind turbines on land, however, we have considered to install those on the ocean which doesn’t worry about space and, by extension, on deep sea which wind turbines could receive more strong wind on. Under these circumstances, research and development of floating wind turbines have been in progress. Especially, NREL designed 5MW floating wind turbine which called as OC3-Hywind system. In this study, we designed three New OC3-Hywind systems which could have better motions by changing the shape of platform of OC3-Hywind system by NREL and confirmed the motions through model test. Depending on positions of a damper which can change center of buoyancy, we named those three models M1, M2 and M3.
