Kamarlouei, M., Hallak, T.S., Gaspar, J.F., Calvário, M. and Guedes Soares, C. (2021), “Optimization of a Torus-shaped Wave Energy Converter Attached to a Hinged Arm”, 40th International Conference on Ocean, Offshore and Arctic Engineering (OMAE2021), 21-30 June, Virtual, Online, Paper: OMAE2021-63729.
This paper presents the adaptation of a torus WEC prime mover to an onshore or nearshore fixed platform, by an hinged arm. An optimization code is developed to obtain the best torus and arm geometry, as well as the power take-off parameters, taking as objective function the maximization of total wave absorbed power. In this paper, the power take-off system is modeled as a simplified damper and spring system, where the parameters are optimized for the phase control of the wave energy converter in each sea state, whereas the optimization process is performed with genetic algorithm. Finally, the optimal result for the productive sea state indicates that the absorbed power is relatively considerable while a better survivability performance is expected from torus WEC compared to conventional truncated prime mover.
