Offshore wind energy is a key focus in the development of new marine energy sources.The integrated development of offshore wind power and deep-sea aquaculture has become a new approach for the comprehensive utilization of marine space.This study takes an integrated structure of offshore wind turbine jacket foundation and cube fish cage as the research object.A series of physical model experiments were conducted at a model scale of 1∶25 to investigate the impact of different wave heights,periods,current speeds,and submergence depths on cable tension response.Results indicated that the tension in the upper and lower windward cables increased with the wave height.For a given wave height,the tension in both cables grew as the wave period increased.For a submergence depth of 0.2 m,the tension in the lower windward cable was slightly greater than that in the upper cable under all tested conditions.As the flow velocity increased,the tension in both cables increased continuously,and the difference in tension between them also widened.The tension in the upper windward cables decreased with greater submergence depth,whereas the tension in the lower windward cable increased.When the submergence depth increased from 0 to 0.6 m(corresponding to 15 m in the prototype),the tension in the upper windward cable decreased by 80.90%,and the tension in the lower windward cable increased by 244.03%.The results of this study can provide a reference for the design and safety analysis of the wind-aquaculture integration structure.
