Abstract
A model test with a power take-off system composed of pulleys, belts and a generator is made and tank tests are carried out in regular waves to evaluate performance of a floating pendulum wave energy converter (FPWEC) proposed by Watabe. A primary conversion efficiency, secondary conversion efficiency and generating efficiency of this device are obtained from a free oscillation tests. Also, two dimensional numerical codes using a boundary element method based on velocity potential theory to estimate the primary conversion efficiency of this device is developed. The result of the code is validated by comparing with the experimental results.
