Abstract

The coastal areas of Japan are estimated to have vast offshore wind energy potential. In order to use large quantities of offshore wind energy, developing a floating body for offshore wind power generation applicable to deep sea areas. Several researches have been made to meet the requirements. In this study, we proposed truss spar and semi-submersible bodies, they have a long track expand about deep water drilling rig operation results. And solved the response and stress characteristics of the floating bodies. And the optimum floating body size and the mooring facilities were determined by the analysis systems.
