Abstract

This paper is based on the premise that “wave energy conversion” is the conversion of the energy of ocean waves into other energy forms for the benefit of the environment. By taking advantage of the diffraction focusing phenomenon, commonly associated with water wave energy conversion, a bimodal buoy called the Antenna Buoy has been developed to both attract and dissipate incident water wave energy. As a result, arrays of the buoy can be deployed to form an effective floating breakwater system. Results from a full-scale experimental study show that an array of buoys, with each buoy pair separated by about 10 body widths, can dissipate up to 65% of the incident wave energy, where the value of the energy dissipation depends on the wave frequency. To arrive at this value, the full-scale test was conducted in a vertical-walled tank, where wall reflections were from “virtual” units in an array. The full-scale model used in the study is based on the averaged wave climate in the central-to-northern waters of the Chesapeake Bay. In addition to being effective in its design operation, the bimodal buoy can be repositioned or removed, as the site situation might require.
