Journal ArticleDOI
Design of oscillating-water-column wave energy converters with an application to self-powered sensor buoys
João C.C. Henriques,J.C.C. Portillo,Luís M.C. Gato,R.P.F. Gomes,Deisemara Ferreira,António F.O. Falcão +5 more
TL;DR: In this article, the authors present a new systematic methodology for optimum design of wave energy converters, which is applied to design two self-powered sensor buoys for long term monitoring based on the oscillating water column principle.
Journal ArticleDOI
Dynamics and control of air turbines in oscillating-water-column wave energy converters: Analyses and case study
TL;DR: In this article, a detailed analysis of the dynamics and control of air turbines and electrical generators in oscillating-water-columns (OWCs) is presented to explain the performance of an OWC device based on the physical behaviour of each system component.
Journal ArticleDOI
Wave energy converter physical model design and testing: The case of floating oscillating-water-columns
J.C.C. Portillo,KM Collins,R.P.F. Gomes,João C.C. Henriques,Luís M.C. Gato,B. Howey,Martyn Hann,Deborah Greaves,António F.O. Falcão +8 more
TL;DR: The model design and testing processes as part of wave energy projects and the results of experimental testing of two types of oscillating-water-column (OWC) wave energy converters (WEC) are presented.
Journal ArticleDOI
Multivariate analysis of the reliability, availability, and maintainability characterizations of a Spar–Buoy wave energy converter farm
Giovanni Rinaldi,J.C.C. Portillo,F Khalid,João C.C. Henriques,Philipp R. Thies,Luís M.C. Gato,Lars Johanning +6 more
TL;DR: It is shown how this type of analysis provides important insights not only to ocean energy farm operators after the deployment of the devices, but also to device developers at the early design stage of wave energy concepts.
Journal ArticleDOI
Compact floating wave energy converters arrays: Mooring loads and survivability through scale physical modelling
R.P.F. Gomes,Luís M.C. Gato,João C.C. Henriques,J.C.C. Portillo,B. Howey,KM Collins,Martyn Hann,Deborah Greaves +7 more
TL;DR: In this article, the authors present the experimental study of different configurations of a five-device array of spar-buoy oscillating-water-column wave energy converters in a wave basin, focusing on the analysis of the devices motion and the mooring line loads.
