碩士 / 國立成功大學 / 土木工程學系 / 106 / Taiwan has a very good condition of the wind field, making the offshore wind power has become one of the most widely promoted renewable energy sources in Taiwan. In the past, the jacket-type offshore wind turbine support structure was mainly for ultimate load analysis and design under extreme environmental conditions. However, this study will focus on the damage analysis and the service life design under fatigue load. In this thesis, according to the specification of the DNVGL-RP-C203 development the offshore wind turbine fatigue analysis and design programs. Firstly, the joint type of the support structure was classified, and then the fatigue damage was calculated by the rainflow counting method combined with S-N curve and Miner's rule. Finally, the Broydeb's method is used to calculate the thickness of the member to reach the offshore wind turbine fatigue life, e.g. with a service life of 20 years. Integrated the support structure finite element model and design load cases into an input file. After considering the ultimate load and fatigue load, the program will automatically read the section of each member for finite element analysis, and conduct the optimal design of the jacket-type foundation by using the API RP 2A-LRFD steel structure design specifications. Therefore, the total design steel weights of the support structure are obtained. Finally, using multi-machine parallel computing techniques will make the windturb.exe as a more complete and efficient analysis and design program of the offshore wind turbine, and provide the engineering industry as a reliable reference source. Note that the computer programs developed by the research team of Shen-Haw Ju are open and free to use.
