Fixed type pendulum wave energy converter is a kind of movable body type wave energy converter and it was invented by Kondo with Muroran Institute of Technology in Japan. Some researches on this device were carried out experimentally and theoretically, and its high energy conversion efficiency was shown. However, this device was not practical used yet, because the initial cost is so expensive as it needs heavy construction in the sea. And also, it is difficult to keep it safety under the critical weather condition like a typhoon is another main reason. So, as a solution strategy for above problems,Furusawa proposed the uplifting type pendulum wave energy converter. Furthermore Watabe proposed the floating type pendulum wave energy converter (FPWEC) which is moored to the seabed with some lines as another solution. Changing from fixed type device to floating type device, we can expect the reduction of initial costs and emergency measures. Watabe carried out some research on FPWEC, but it is not enough to say that the design method for this device was established.In this paper, we have made a test model of FPWEC for tank test and some tests were carried out as a first step of development for this device.To estimate the performance of this device, we have measured power output and body motion in regular waves.
