The hydrodynamic aspect of a wave energy extracting caisson breakwater under random wave actoins is studied in this paper,The pressure drop through the air nozzle is linearized by means of least square method. To solve the potential flows a localized finite element method is adopted. The theoretic results show that the efficiency of the wave power appears high at various frequencies. The wave forces especially the overturning moments, are smaller than those on so vertical breakwaters.

Presented in this paper is a systematic experiment and research on the wave dissipation effect of breakwaters built on perforated box caissons with narrow orffices. The result of the experiment and research has shown that, the reduction factor of horizontal wave force is generally between 0.6 and 0. 8, which can meet the requirements of wave dissipation and the decrease of wave reflection and the perforated box caisson type breakwater with narrow orifices is an acceptable type. The wave-dissipation effect by the action of short period waves is more significant than that by the action of long period waves.
