Abstract: A wave energy converter to convert energy conveyed in ocean waves propagating in a wave propagation direction in an ocean environment and received at the converter into generated power includes a plurality of columns which are in fluidic communication via corresponding ports to the ocean waves received at the converter. The ports are arranged substantially in series along the wave propagation direction, and the ports are of progressively greater depth into the ocean environment along the wave propagation direction to cause the ocean waves to propagate in a downwardly-directed manner when received at the ports. The plurality of columns are arranged so that that their elongate axes are substantially aligned along a first direction, and that the ports have corresponding port angles relative to the first direction which are progressively larger as the ports (50) are of progressively greater depth.

Abstract: An ocean wave energy system for generating power from ocean waves includes a platform supporting an array of hollow columns whose respective lower ends are in fluidic communication with ocean waves and whose respective upper ends are in air communication with a turbine arrangement such that wave motion occurring at the lower ends is operable to cause air movement within the columns for propelling the turbine arrangement to generate power output. The system further includes one or more position-adjustable and/or angle-adjustable submerged structures near the lower ends of the columns for forming ocean waves propagating in operation towards the lower ends of the columns to couple the waves in a controllable manner into the hollow columns.
