Experimental study of wave energy converter arrays adapted to a semi-submersibl...
Kamarlouei, M.; Gaspar, José; Calvário, Miguel; Hallak, T. S.; Mendes, Mário J. G. C.; Thiebaut, F.; Guedes Soares, CarlosThe design of an offshore wind turbine floating platform seeks to minimize platform pitching motions that otherwise generate large accelerations and loads on the turbine, nacelle and blades, and decrease their lifetime. This objective is harder to achieve as the upscaling to more powerful wind turbines amplify the effects of pitching motions since the wind turbines’ height and mass are higher. Thus, innovative ...

Kamarlouei, M.; Gaspar, José; Calvário, Miguel; Hallak, T. S.; Mendes, Mário J. G. C.; Thiebaut, F.; Soares, Carlos GuedesThis paper presents an initial experimental study of wave energy converters concentrically arranged and attached on a floating offshore platform model. The 1:27 scale model, has been designed, built and tested, in two main situations, without and with twelve cone shape wave energy converters. To simulate the power take-off system in each wave energy converter, rotational friction dampers have been installed on ...

Kamarlouei, Mojtaba; Gaspar, José F.; Calvário, Miguel; Hallak, Thiago S.; Mendes, Mário J. G. C.; Thiebaut, Florent; Guedes Soares, CarlosExperimental results of the dynamics of a small scale concentric wave energy converter array adapted to a floating offshore platform are presented. A small scale prototype is tested without and with twelve conical heaving point absorbers. The free decay and regular wave tests are carried out in an ocean basin to understand the hydrodynamic interactions between various elements of the floating offshore platform ...
Numerical and experimental analysis of a hybrid wind-wave offshore floating pla...
Hallak, Thiago S.; Gaspar, José F.; Kamarlouei, Mojtaba; Calvário, Miguel; Gonçalves Cavaco Mendes, Mário José; Thiebaut, Florent; Guedes Soares, CarlosThis paper presents a study regarding a novel hybrid concept for both wind and wave energy offshore. The concept resembles a semi-submersible wind platform with a larger number of columns. Wave Energy Devices such as point absorbers are to be displayed around the unit, capturing wave energy while heaving and also enhancing the stability of the platform. In this paper, a first numerical study of the platform’s h...
