In this paper, linear frequency-domain hydroelastic analysis is performed for investigating the behavior of a spar-type supporting platform of a floating offshore wind turbine considering the platform’s flexibility. A “dry” mode superposition approach is utilized, where the flexible mode shapes are determined through the application of a FEM based structural model. The diffraction/radiation problem is solved using the boundary integral equation method. Focus is given on the flexible modes’ generalized hydrodynamic forcing and responses, the spar’s hydroelastic response and the coupling effects between the flexible and the rigid-body modes. For irregular waves, the effect of the peak period on the response spectra and the hydroelastic response is analyzed.
