Sandia catalogs test site infrastructure, met-ocean data, and resource characteristics for wave energy converter test and utility-scale deployment sites in the United States using consistent methodologies, including those developed by the international standards organization, the International Electrotechnical Commission (IEC). This information allows wave energy planners and technology developers to select appropriate sites for commercial wave farms and provides critical inputs for device design and testing.
Our resource catalogs provide joint probability distributions (JPDs) of occurrence and contribution to energy, mean monthly values of wave statistics suggested by the IEC technical specification, cumulative probability distributions, weather windows, representative spectrum, extreme sea states, and wind and ocean current statistics.
The Inverse First-Order Reliability Method (I-FORM) considers both wave height and period to predict the frequency of occurrence of extreme sea states which can damage MHK devices. Sandia’s modified I-FORM, which uses principal components, better represents the data and should contribute to the development of more realistic representations of environmental contours of extreme sea states for use in survivability analysis.
