5. The forward motion of the wave also exerts a lateral surge force FH on the WEC device. For example, the deformable member may be capable of undergoing a reversible change of shape in response to an applied force. Preferably, size and shape of the fixed member are selected such that it floats just below the surface of the ocean.
An element may have a different length to one or more other elements, so that the composite response is a combination of the responses each of the different length elements. In tidal flow regions, that is, where a moored body is acted on by tidal streams or tidal turning, the drift forces can pull the mooring sizeable distances in one direction (horizontally) and then the other as the tide changes. In a wave energy environment, this device would very quickly overheat and would be unable to dissipate the energy that deep sea waves contain. The damping member may comprise a resiliently deformable material that exhibits a reversible non-linear stress-strain response. In other embodiments, the cross-sectional area (thickness) of an element may differ from that of one or more other elements, so that the composite response is a combination of the responses each of the different thickness elements. The words “comprises/comprising” and the words “having/including” when used herein with reference to the present invention are used to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
Typically, the total cross sectional area of the mooring line may be reduced by more than 30% when compared with traditional mooring lines, significantly reducing costs. 28 a. Steel connectors 7 are provided at either end of the component 2, so that the component is connectable between a floating body and the seabed. The damping member may thus act as an energy storage device, which temporarily stores energy captured from the waves so that it can be fed back into a power take off system associated with the WEC device. Dolor de rodilla al arrodillarse . For example, the member may have sufficient inherent inertia to prevent substantial movement thereof by wave motion. For example, for a water depth of 5 meters, the floating body may drift to an offset position from equilibrium.

The pumped water is used to capture energy from the device. In general, the larger the wave, the more energy it contains, and therefore, the more energy that can be obtained from it. Specifically, the amount of energy which may be obtained from waves is determined by wave height, wave speed, wavelength, and water density.

This means that the scope and the seabed footprint of the mooring system may be reduced, while providing an improved response to a variety of environmental loads. This maximises the vertical component of the force applied to the moveable member while providing sufficient horizontal counterforce to counteract lateral surge forces. SUMMARY OF THE INVENTION The present invention relates to a damper for damping the reactionary motion of a wave energy conversion device to wave motion, comprising a damping energy absorber having a reversible non-linear stress-strain response, arranged to damp the reactionary motion of the WEC. According to a third aspect of the invention, there is provided a wave energy conversion device, comprising a moveable member, a fixed member and a coupling provided therebetween to convert relative movement between the moveable member and the fixed member in response to wave motion into energy; wherein said coupling comprises a damping member having a reversible non-linear stress strain response.
According to an aspect of the invention, a plurality of damping members may be provided, wherein each damping member is arranged to damp the movement of the device substantially along one axis only. Desirably, it exhibits a plurality of non-linear stress-strain responses within its operating range. Desirably it exhibits a plurality of non-linear stress-strain responses within its operating range. In another embodiment, the damping member is provided with a plurality of electronic teeth. This arrangement allows the damping structure to work in a single direction only, leaving the float free to move in other directions. FIG. 10 shows a WEC device 101 of the point absorber type, comprising a damping structure 102 according to the present invention. FIG. 18 shows a WEC device 181 comprising a damping structure 182. The WEC device is similar to that shown in FIGS.

The composite stress-strain profile may have a number of points of non-linearity, such that the deformable element provides a sharp increase in counterforce at several thresholds or levels of applied force, with a substantially linear response between those points. In the embodiment shown, several elements 6 a are relatively short, whereas elements 6 b are longer. In the embodiment shown, pitch and surge are both controlled by a single set of dampers.
