Abstract

The springing response of a tension-leg-platform wind turbine (TLPWT) excited by the third-harmonic force of an extreme regular wave is investigated using an integrated (aero-hydro-mooring) numerical model developed and presented in this paper. The numerical model comprises a hybrid hydrodynamic model, which employs fully nonlinear potential theory for wave kinematic prediction and non-diffracting potential theory for wave force prediction, to simulate extreme wave and predict associated wave forces accurately and efficiently. Numerical simulations are carried out for the interaction of a floating TLPWT with waves. The focus is on the TLPWT motions, principally excited by the higher-order harmonic wave forces. In particular, the springing response at the triple wave frequency of a regular wave is investigated, together with the wind turbine response and the tensions in the mooring lines.
