碩士 / 國立高雄海洋科技大學 / 輪機工程研究所 / 98 / This research analyzes the basic design of a raft type off-shore platform for renewable energy systems such as mini-size wind power systems and solar energy systems. In the design, a 500W wind power generator system is installed on the top of the platform, and the height of the turbine frame is 2.8 m above water. The platform is towable, with size of 8x8x2 m and pay load of 300-1000kg.
The main charters analyzed in this research for the platform include locations of center of buoyancy and center of gravity, the distance between the buoy center and the meta-center (BM), and the distance between the center of gravity and the meta-center (GM). A general purpose CAD system, SolidWorks, is used to estimate the volumes and the positions of centers of geometry calculated for the raft and to validate to the formulation derived.
The method to determine the GM of the raft type platform is different from that of traditional ships. When calculating GM, floating entities of the platform are divided into x-rafts, y-rafts, and ballast raft. The inclined angles of the platform are divided into 3 regions, by the angle when the tip of y-raft is submerged and the angle when the x-raft is completely submerged.
The results indicate that the geometry of the inclined raft remains symmetric up to 27º and the GM of the raft type platform is very high, about 32 meters when the platform inclined angle is within 3º
