bottom-fixed wave and offshore wind hybrids and ground breaking systems based on an evolution of the current substructures used by the offshore wind industry to accommodate a wec. alternatively a bottom-fixed hybrid could be conceived by integrating a wec into an existing offshore wind turbine strengthening the substructure as required . notwithstanding; none of both alternatives are not without difficulty and further research should be conducted to understand the interaction between the wec and the offshore wind substructure
