- A harbor oscillating water column wave-energy device has been selected for the Indian pilot wave-energy program. The site has a water depth of about 12 m and an average annual wave-power potential of 13 kW/m. Such sites are attractive locations for fishing breakwaters. Due to the relatively low ower potential, these oscillating water column devices arc intended to be modules of a multifunctional breakwater. The present paper highlights the results of the sealemodel experiments carried out on a prototype wave-energy caisson. ASCE.
