“…Consequently, many e orts have been dedicated to studying the dynamics of the TLP. In this regard, analyses of the response of the TLP with a hydro-pneumatic tensioner [8] and the coupled surge and heave dynamics of the TLP [9] have been carried out. However, the complexity of the oating wind turbine is considerably more than that of a single TLP due to the various wind and wave loading and interactions between the oating platform and the wind turbine.…”

In this paper, a conceptual model is proposed to investigate the nonlinear dynamics of the transverse vibrations of the oating wind turbine. The conceptual models are the best tools to capture the most important phenomena in the dynamic response of the systems. First, the surge dynamics of the Tension Leg Platforms (TLP) is modeled as a nonlinear spring. Then, the fore-aft motions of the wind turbine are modeled as a spring-mass system. Then, simulations are carried out to evaluate the time response of the proposed model. Afterward, the FAST code is utilized to verify the proposed model. The internal resonance and its combinations with the primary resonance are studied by the multiple time scale method. Finally, the frequency response curve is obtained, and the e ect of the various parameters of the system on the amplitude and the stability of the oscillations are investigated.
