A floating-type wave power generating system has an OCW (Oscillating Water Column). The device captures the wave energy using the heaving, pitching and surging motion of the device and the heaving motion of the OWC. The investigations are motivated by the experiments and the numerical analyses undertaken to find a possibility different from an OWC-type floating device, e.g. the Mighty Whale of the Japan Marine Science and Technology Center. The 2-dimensional numerical method for analyzing a floating body with an OWC-type wave energy conversion device is introduced where the eigenfunction expansion method is described under the condition that the linear water wave theory is applicable. It is confirmed that these solutions give good agreement with several experimental results in our previous paper. The 2-D optimal profiles are eliminated according to conditions different from high efficiency, i.e. the minimum size per one power unit and so on. The investigations are established by many calculations, and the optimal load damping coefficient is solved. In this way we can obtain the optimal profiles considered for the construction cost.
