The performance of a backward bent duct buoy (BBDB) is analysed experimentally under the action of regular and random waves. This is a floating type of wave energy conversion device with an oscillating water column at the front side as an energy tapping device. The air displaced due to rising and falling water surface in the oscillating water column is used to drive a turbine which generates power. The device captures oscillating wave energy using the heaving, pitching, surging motion of BBDB and the heaving motion of OWC. The scaled model was fabricated in IITMadras with a geometric scale of 1:8 using acrylic sheets. The tests were carried out in a wave flume. The behaviour and pneumatic efficiency of device were analysed for two different configurations of mooring system.
