This study investigates the influence of module-to-module connection types on the hydrodynamic behavioral characteristics of multi-connected floating structures in ocean environments. Numerical models representing various connection configurations were developed, and time-domain global performance analyses were conducted to evaluate the motions of the floating bodies and the internal forces at connection locations. Three connection types—fixed, elastic connection, and hinged—were applied to identical structural modules for direct comparison. The resulting motion responses, connection forces and moment were analyzed to identify the most rational connection strategy for very large floating structure (VLFS) systems. The findings highlight notable differences in structural responses depending on connection stiffness. Further investigation of internal force and stress levels within individual modules is recommended to refine and validate optimal connection design strategies.
