摘要：

For modeling floating offshore wind turbine (FOWT) structure, it is questionable whether to consider the flexibility ofthe main floater while it is alm ost common to account for the flexibility of the tower and blades. Most of the numerical simulation tools developed consider the floater to be a rigid body and flexibility of floating structure is not considered. The present authors have developed a coupled simulation tool wh ich combines hydrodynamic analysis and aerodynamic analysis codes. With the present simulation code, flexibility of floating structure is incorporated into the analysis of FOWT systems. The present research is thus targeted to overcome the limitation ofthe floating structure as a rigid body. Effects of modeling level, Le. the difference between flexible foundation vs rigid foundation is cIarified. Transient response ofSPAR type floating foundation for 5MW wind turbine under the increased thrust load due to malfunction ofthe pitch control system is considered.
