A series of study on wave power utilization conducted during the period of 1976―1986 by the group of staffs of the institute is summarized. Three kinds of power extractor belonging to the so-called coastal fixed type were invented and studied in laboratory. Among them the water turbine and the pendular systems were subsequently studied at the field test plant constructed at Port Muroran which shows the latter has an excellent power conversion efficiency. An approach for predicting the power extracted by the fixed type extractors has been proposed employing analyses of wave spectral transformation and of three dimensional kinematics of extractors. Simulations for maximizing the power charged into lead battery and for the optimal load condition of power generation have been performed. A case study on practical application of the wave power utilization has been done for Yagishiri Island, one of remote islands far from main lands which are the most prospective locations to realize the wave power utilization in the near future.
