The WEC system was modeled using the hydrodynamic package OrcaFlex, over a range of regular and irregular sea-states of varying wave height and period. Four optimization steps were made to the model, altering parameters...

... or hurricanes, the theoretical wave power density could reach 1,600 kW/m. However, higher wave height and period could damage the energy capture devices. This project explores the correlation pattern between available wave power density hotspots and hurricane-induced wave distribution within 10 years (2010-2019...
