Abstract
The first objective of this work is to compare the two floating offshore wind turbine simulation packages; (DIFFRAC+aNySIM) and (WAMIT+FAST). The focus of this study is on second-order wave loads; therefore, first- and second-order wave loads are applied to a structure sequentially for a detailed comparison and a more precise analysis of the effects of the second-order loads. aNySIM does not have the capability to model flexible bodies, so the simulations performed in this tool are done assuming a rigid body. FAST also assumes that the platform is rigid but can account for the flexibility of the tower. The second objective is to study the effects of the second-order loads on the response of a tension-leg platform (TLP) floating wind turbine. The flexibility of the tower must be considered for this investigation; therefore, only FAST is used.
