“…Figure 3 shows the components of the model (1) and the arrangement of the equipment. At one end, the spine (5) was bolted to the steel plate (2). At the other end, the spine entered a slot in a polycarbonate end piece (3) that was bolted to the end.…”

“…The moving parts will translate the wave motion to the device machinery and either use such a motion to mechanically drive an on-board power take-off or use the motion to do work on a fluid, which can then be dealt with on shore. A comprehensive description of the different types of WEC is found on the EMEC website 1 and a review of the many different types of WEC and their necessary power equipment has been carried out by [2]. One of the difficulties facing the WEC industry is the number of concepts in development; the lack of design convergence has led to a large range of devices spanning concept designs to working prototypes.…”

A wide range of wave energy converter (WEC) designs exists, and the SeaWave WEC uses an unstable buckled spine mode of operation. The SeaWave consists of a hose and buckled spine-diaphragm, which pumps air along the device under wave action. A physical model and finite element analysis (FEA) is compared to a previous theoretical model in this paper. The FE model was developed in ABAQUS 6.14 using shell, solid and contact elements and the analysis was done with a quasi-static approach to reduce the computational costs. The physical model was a scale version of the novel arrangement of the spine and diaphragm made from steel, polycarbonate and latex rubber. Geometry of the deformed device was investigated results showed an increase in transverse and longitudinal curvature as the compression rate increased. The FEA tended to overestimate the bending stiffness of the model, and hence the transverse curvature, because certain behaviours of the physical model were not captured. The force required to switch from one buckled state to another was measured both in the physical and FEA models and the potential energy storage was estimated to be 0.5 J/m of device at a compression rate of 0.1%.

“…In general terms, for the classification of the proposed system once the mechanism has been optimized, it will be used the approach tackled by López et al, [5] to categorize WECs, according to three characteristics: location, size and working principle. The location is given with respect to the distance from the coast, and in this sense there are three types of converters: onshore, nearshore and offshore devices.…”

“…The knowledge and experiences gained lead to a development status that is ready for the market [4], while it is true that these devices are in early stages compared to other renewable technologies (solar, wind) and compared with conventional fossil plants, and most importantly, there is still no design outweighing over the rest [5].…”

Abstract. The development and exploitation of new sources of clean energy that do not depend on traditional sources based on the use of fossil fuels, is the focus of this research, which starts with the optimization of an invention capable of transforming a reciprocating rectilinear motion into continuous circular motion in a very efficient way, to be used in the development of a Wave Energy Converter (WEC), capable of operating with low wave height and taking advantage of the oscillating movement of the waves both when rising, and when lowering, unlike other similar devices that harness it only in one way.
