Abstract
In recent years, there are activities of making fish farms in offshore area because of the generation of the red tide and the deterioration of the surrounding environment by overcrowded cultivation in coast area. However, following problems occur if fish farms were made in offshore area. First, it is difficult to use gravity type breakwater to make calmness water area for large depth. Second, energy supply is not easy because there is far away from the land. To resolve these problems, we install floating breakwater instead of a gravity type breakwater and get energy to be necessary in fish farms from the motion of the floating breakwater at the same time to reduce the wave. Then we set the pendulum on the floating breakwater model with reverse-trapezoid section and experimented to get energy from the swing of the pendulum by the movement of the wave. In this paper, we present the result of the experiments and describe basic characteristics of this model.
