영문 초록

The importance of tidal energy has increased steadily throughout the world, and it is recognized as the most reliable energy resource from the ocean. It has great advantages compared to other renewable energy resources due to high energy density in sea water, reliability and predictability. There are many suitable sites for the application of tidal current power (TCP) in Korea because the strong current water area are located in the western and southern coasts with high tidal range up to 10m. Even though many tidal turbines are demonstrated to increase the power efficiency, the cost-saving technologies are still required for economical design of the device. Since the structure and installation cost is dominant in development expense of TCP system, economical supporting structure and installation procedure should be developed. Because the ground conditions of most installation site are rocky bed due to its rapid current, gravity structures are regarded as the most competitive solutions than any other piled structures. Gravity base caisson support structure can be installed with small equipment and the stability can be increased by the injection underwater concrete after the installation. To design the caisson structure which is suitable for the TCP system, integrated load analysis has been carried out using Tidal Bladed considering various design load cases. Multi-body dynamic method was used for interaction between components and dynamic loading on the TCP system was simulated. Calculated load was applied to the design of caisson structure and findings have been summarized in this paper.
