To reduce impacts of energy shortage and sustain developments of the human society, exploring all kinds of renewable energy becomes an urgent task. Taiwan has started to develop offshore renewable energy to replace fossil fuels and has been satisfying most of the energy consumption over the decades. Kuroshio passes through the east coast of Taiwan, and the water depth in this region is about 500~1000 m. The floating and submerged platform system is suitable for deep water area and good for any water depth. This study is one of the subprojects of an integrated project: â??A Study on Harvesting Marine Current Powerâ?. The main goal of the study is the analysis and design of the second version of the submerged energy capture system which includes the shroud, diversion wing and the rudder. This design can increase the pressure gradient between the inflow and outflow and the flow velocity inside the shroud can be enhanced, thus improving the efficiency of the turbine. The attack angle of the wing can be adjusted to control the lifting of the platform system. While, the rudder is used to control the flow direction be always perpendicular to the entrance face of the capture system. The optimal design is verified by the numerical simulation and experimental measurement. The project will match the integrated projects (four other subprojects) which will complete the design and construction of a prototype of the marine floating structure system and the implementation of the Kuroshio Energy collection might be fulfilled in the near future.
