Design of an Innovative Point Array Offshore Floating Wind Turbine System and Analysis of Hydrodynamic Coupling Response Law

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. The article aims to conduct conceptual design and hydrodynamic research on a new offshore multiwind turbine-integrated device dot matrix floating (DMF). By combining theoretical analysis, numerical simulation, and testing experiments, the operational feasibility and hydrodynamic superiority of DMF are determined. These provide reference and theoretical basis for the development of new offshore wind power equipment.image (c) 2023 WILEY-VCH GmbH
