Wave energy resource off the French coasts: the ANEMOC database applied to the energy yield evaluation of Wave Energy Converters

Abstract

A numerical wave database called ANEMOC has been built by EDF R&D LNHE by hindcasting wave conditions over a period of 23 years and 8 months, between 1979 and 2002. The simulations of wave conditions are carried out with the third-generation spectral wave modelling software TOMAWAC and are driven by wind fields from the ERA-40 meteorological reanalysis produced by the European Centre for Medium-range Weather Forecast. Two nested models, an oceanic one and a coastal one, which zooms on the French coasts of Atlantic Ocean, English Channel and North Sea, have been implemented. The results have been validated with buoy data over a period of two years, and can be used to determine medium wave conditions as well as statistically extrapolated extreme wave heights.

After a description of the main characteristics of the database, the paper focuses on the application of such a database for evaluating the wave energy resource and the wave energy yield of Wave Energy Converter (WEC) technologies in Europe, and in particular off the French coasts.

Wave energy resource off the French coasts: the ANEMOC database applied to the energy yield evaluation of Wave Energy Converters is located in France.
