Abstract
The Japanese Ministry of Transport has been developing a wave power extracting caisson breakwater to absorb wave power and convert it into electric power. The caisson of the breakwater has an air chamber which is a wave power converter of oscillating water column type.
A test breakwater was constructed in the summer of 1989 in Sakata Port and the breakwater began the power generation in the winter of 1989. The caisson has the lenght of 20m and the rated power of the generator is 60kW. The system works well as designed. The experiment is being conducted successfully. In this report, the wave power conversion in the field experiment is described.
