Comunicação apresentada na EWTEC 2007 - 7th European Wave and Tidal Energy Conference, Porto, Portugal, 11-13 September 2007http://hdl.handle.net/10400.9/410This paper investigates the dependency of wave energy conversion on the spectral bandwidth of sea-states. To this aim, the performance of an axisymmetrical Wave Energy Converter is assessed in the frequency domain by using a stochastic model in two far different wave climates (Portugal and North Sea) both represented by more than 23000 energy spectral densities obtained from measurements. The correlation between the performance and various bandwidth parameters found in the literature is observed. Then, refined methods for predicting the long-term converted wave energy based on wave statistics including spectral bandwidth are compared to more common procedures and conclusions are drawn.engWave energy converterPerformace assessementSpectral bandwithStochastic modellingconference object
