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.

A Wells turbine operating under irregular wave conditions has been analyzed theoretically. It is shown that the turbine performance depends on a unique parameter, including characteristic parameters of the irregular wave, turbine speed and dimensions of the turbine and air chamber. In order to obtain the optimum value of this parameter, a model test has been performed using a computer-controlled wind tunnel, which can simulate arbitrary oscillating flows based on spectra of irregular waves. From this value a set of optimum dimensions of a Wells turbine system can be determined. Furthermore, starting and running characteristics of the Wells turbine have been obtained by a computer simulation. It is possible to predict the optimum value of the parameter and behavior of the output coefficient by computer simulation.
