Abstract: To reduce the Levelized Cost of Energy (LCoE) for floating offshore wind turbines (FOWTs), there is a trend towards their development in larger scales. Platform components have also become longer and more flexible, which may lead to unexpected flexible phenomena under external loads. Furthermore, some platforms intentionally incorporate flexible components during design to leverage these effects for enhancing overall performance. These flexible phenomena contradict the traditional assumption of treating platforms as rigid bodies. Currently, the flexible effects of platforms have garnered widespread academic attention, leading to a series of related studies, yet a systematic review is lacking. To address this, this paper first introduces the evolution of modeling FOWT components from rigid bodies to flexible bodies, elucidating the necessity of considering platform flexibility effects in accurate modeling. Subsequently, based on the mechanism of introducing flexible effects, flexible platforms are categorized into passive and active types, with detailed discussions on the initial consensus reached in various platforms after considering flexible effects, such as underestimating structural fatigue life and inducing resonance to amplify platform motion responses. Finally, the paper highlights the shortcomings in current research on flexible platforms. For passive flexible platforms, there is a lack of recognized guidelines for predicting the necessity of considering platform flexibility effects to avoid wasting computational resources. In designing active flexible platforms, there is still significant room for improvement in selecting and optimizing characteristic parameters.Abstract: To reduce the Levelized Cost of Energy (LCoE) for floating offshore wind turbines (FOWTs), there is a trend towards their development in larger scales.
