Abstract

This paper proposes a novel floating structure configuration employing prefabricated hexagonal floating units as fundamental components, interconnected by elastic connectors in a staggered arrangement pattern. To quantitatively evaluate the engineering applicability of this innovative structure, hydrodynamic response analysis is conducted using ANSYS Workbench software. The study systematically investigates the influence mechanisms of three critical factors on the motion responses of the multi-body floating system： the geometric configuration of floating units, rotational stiffness of connectors, and wave incidence angles. The results demonstrate that hexagonal floating arrays significantly reduce translational displacement amplitudes compared to other configurations, effectively minimizing peak mooring tensions. Optimizing the design of elastic connector can effectively suppress relative rotational displacement between adjacent floating units while balancing peak bending moments in the connectors, thereby synergistically enhancing wave resistance and motion stability. Further analysis reveals that the balanced moment of inertia and geometric characteristics of hexagonal floating arrays enable superior motion response performance across all wave incidence angles.
