Grant: Engage Grants Program

It is well known that ocean waves contain the highest energy density. Propelled by the worldwide demand forrenewable energy, ocean wave energy has the potential to be harvested and commercialized. Although theeconomic and environmental consequences of wave power are still matters of concern, technical possibility andchallenges have already spurred extensive research around the world.Recently, the Grey Island Energy (GIE) Inc. has developed an innovative wave energy device, SeaWEED, forwave energy conversion. The device has floats semi-submerged on the surface of water and inherently facesinto the direction of waves. The wave-induced motions of the floats are converted electricity via hydraulicpower take-off systems housed inside each float. It is GIE's goal to make the device ready for commercialdeployment. To meet the goal, it is important to optimize the SeaWEED system to reach maximum powertake-off efficiency and to evaluate the performance of the device in extreme sea conditions. The proposedresearch will focus on the hydrodynamic optimization of the float geometry, rod length and on the survivabilityof the system in large waves. Investigations will be carried out to determine the induced forces on the joint,which can be used for structural analysis and fatigue assessment. The outcome of the project will enable GIE tofinalize the prototype.The proposed research will contribute nationally and internationally to the field of wave energy conversion.The project will enable GIE to further develop a larger prototype for operations in selected sites in Europe. Thistype of system is unique internationally and will allow Canada to commercialize green energy systems andmarket them in Europe. It will ultimately benefit the Canadian economy. From this Engage project, a long-termcollaborative relationship will be developed between the research team at Memorial and GIE.
