WAVE FORCE ESTIMATION ON A TOWER OF OCEAN WIND FARM USING A WAVE SIMULATOR “CADMAS-SURF”

Abstract

Wind farm at sea must be one of important projects in Japan. Although several mono tower and mono pile type wind turbines are in operation in North Sea having the flat sea bed, there is a problem of how to estimate wave loads on such type of structure which would be built on a slope of the sea bed around Japan. In this study, estimation of wave forces acting on such a tower using both a simulation of wave by “CADMAS-SURF” and a calculation of Morison's equation is taken on trial. And it is found that this wave force estimation method gives good results for the condition on the slope where other estimation methods are not effective.
