The need to exploit enhanced wind resources far offshore as well as in deep waters requires the use of floating support structures to become economically viable. The conventional three-bladed horizontal axis wind turbine may not continue to be the optimal design for floating applications. Therefore it is important to assess alternative concepts in this context that may be more suitable. Vertical axis wind turbines (VAWTs) are a promising concept, and it is important to first understand the coupled and relatively complex dynamics of floating VAWTs to assess their technical feasibility. As part of this task, a series of articles have been developed to present a comprehensive literature review covering the various areas of engineering expertise required to understand the coupled dynamics involved in floating VAWTs. This second article focuses on the modelling of mooring systems and structural behaviour of floating VAWTs, discussing various mathematical models and their suitability within the context of developing a model of coupled dynamics for. Emphasis is placed on computational aspects of model selection and development as computational efficiency is an important aspect during preliminary design stages. This paper has been written both for researchers new to this research area, outlining underlying theory whilst providing a comprehensive review of the latest work, and for experts in this area, providing a comprehensive list of the relevant references where the details of modelling approaches may be found.

“…Wayman et al [11,12] studied the dynamic response of various wind turbine foundations under different environmental loads. Sweetman et al [13][14][15] applied the law of conservation of momentum to calculate the large-scale motion of floating wind turbine platform in wind and waves. Nielsen et al [16,17] combined the aerodynamic follow-up elastic model HAWC2 with the simo/ riflex program of the hydrodynamic module and the anchoring module, designed the Hywind spar floating foundation to support the 5 MW wind turbine, developed the relevant control system, and compared the calculation results with the results of the model test.…”

The new lattice floating wind turbine integrated system (also known as dot matrix floating wind turbine, and hereinafter referred to as DMF) is proposed as a new concept. More far reaching, it has obvious advantages over the traditional floating wind turbine scheme in terms of structural cost and motion stability, which provides a new idea for the development of offshore wind power energy. First, the structural parameters and mechanical model of DMF are analyzed to determine the feasibility and superiority of the overall scheme of the new lattice foundation. It is concluded that the stability of DMF in pitching motion is 70% higher than that of the traditional OC4 system. In order to further verify the feasibility of the DMF system and the accuracy of the theoretical model, based on the similarity theory, the research carried out the small‐scale prototype processing of DMF and the simulation experiment of wind wave flume. The test results are in good agreement with the simulation data. This study provides a reference and theoretical basis for the research and development of offshore multi wind turbine combined equipment and hydrodynamic stability optimization. It has certain theoretical guiding significance and economic development value.

“…Some preliminary outcomes of a comparison analyses between the experimental results on a 1:40 model of OC3-Hywind spar obtained in the DHI Offshore Wave Basin in Hørsholm (Denmark), and the corresponding response simulated through an aero-hydro-servo-elastic simulation FAST tool was presented by Tomasicchio et al [42]. Finally, many studies of Floating Offshore Wind Turbines have been also conducted recently [43][44][45][46][47]. The dynamic behaviour of SB floaters has also been studied numerically [48][49][50][51].…”
