Abstract—This study introduces an innovative concept that integrates offshore floating wind turbines with aquaculture cages, termed the Dot Matrix Floating (DMF) integration system for new offshore fisheries. To evaluate the safety and hydrodynamic operational adaptability of the overall DMF structural system, the investigation was conducted through three primary approaches: structural strength reliability analysis, numerical simulation of hydrodynamic responses, and small-scale prototype flume experiments. Initially, a multi-wind turbine wake model was developed, and fluid-structure interaction simulations were employed to characterize the variation patterns of multi-wind load wakes within the DMF structure. Subsequently, the validity of the hydrodynamic response simulations was confirmed by comparing numerical results with experimental data obtained from wave-current flume tests. Additionally, by examining the hydrodynamic response behaviors of the DMF under various mooring configurations, the study identified an optimal mooring strategy suitable for multi-wind turbine integrated systems. Finite element analysis further demonstrated that the overall structural stresses remain within acceptable safety limits. Ultimately, through the combined application of DMF modeling and finite element numerical simulations, an integrated analytical framework encompassing aerodynamics, hydrodynamics, and structural mechanics for multiple wind turbines was established. This framework offers valuable guidance and a reference point for addressing critical mechanical challenges in the development of novel floating offshore equipment.
