<p>The wave energy device (10) incorporates at least one stabilising chamber (40) for influencing the motion of the device (10) in response to waves. The stabilising chamber (40) is open at the bottom to the sea, and has a closable port (41) at the top of the stabilising chamber (40) for controlling air flow into and out of the stabilising chamber (40) resulting from changes in level of the seawater inside the stabilising chamber (40). Appropriate timing of an opening and closing sequence of the port (41) is used to produce air pressure forces in the stabilising chamber acting on the device in a manner to control the heave and pitch components of the motion of the device. Pref. chamber is provided at the bows and/or at the stern of the device, and the chamber(s) might define a water plane area of about 10% of the water plane of the device. The ports may comprise a number of hinged louvres, with electric drive units for controlling the position of the louvres in response to the signal.</p> |
