Abstract

This study investigates the dynamic behavior of offshore wind turbine support structures under wave and wind loads This study is divided into three parts The first part is the calculation module of wave loads according to the standards (DNV-RP-C205) where the Morison equation is included to calculate the wave loads on circular cylinder members and the Airy wave theory and the Stokes second-order theory are used to describe the wave kinematics The second part is the calculation module of wind loads while the wind loading is calculated by programs TurbSim and FAST which were developed by NREL (National Renewable Energy Laboratory) For the last part the loading calculated by the modules of the wave and wind will be added into the finite element mesh using a mesh generation program (WINDTURB) for the offshore wind turbine support structures Finite element analysis program AN is thus used to perform the structural analysis Then the analysis and discussion of the behavior of offshore wind turbine support structures under wave and wind loads It is noted that the computer programs developed by the research group of Shen-Haw Ju are open sources and free to be used
