© 2019 IEEE. The oscillating water column (OWC) is a common type of wave energy converter (WEC). It has been the subject of study and development for several decades. Multi-chamber oscillating water column (MC-OWC) devices or arrays have the advantage of being more efficient in energy extraction compared to a single chamber system, particularly in more chaotic sea states. In this study, a series of wave-flume experiments were conducted under regular wave examine the wave power extraction of the fixed MC-OWC device. In this paper, the effects of device draughts on the power extraction were examined. The experimental results show that device draught was found to be a crucial parameter that could tune the device to a range of wave conditions; hence improving the capture width ratio.
