In recent years, the number of offshore floating structures has been growing and is expected to continue growing. Due climate change, frequency severity extreme waves are increasing. Numerical models can be a strategic tool in reliable design optimization marine structures. However, numerical parameters tuned plays crucial role, as they could limit model's applicability reliability. Furthermore, there many challenges modelling wave-structure interaction. Among these challenges, simulation one-dimensional tethers great concern when dealing with moored this study, 3D model developed based on Smoothed Particle Hydrodynamics (SPH) technique. This hydrodynamic coupled multi-body solver for dynamic analysis moorings three-dimensional flume, focused ocean generated piston-type wave-maker propagated until impact structure. The predicts wave profile, forces, structural dynamics, validated by comparing results against experimental data.

Highly nonlinear near-breaking and spilling breaking wave groups are common extreme events in the ocean. Accurate force prediction on offshore ocean structures these conditions based numerical approaches remains a problem of great practical importance. Most previous studies have concentrated non-breaking forces rigid structures. Taking advantage smoothed particle hydrodynamics (SPH) method, this paper addresses presents development validation model for highly waves interacting with vertical cylindrical structure using SPH-based DualSPHysics solver. Open boundaries applied generation conditions. The free-surface elevation flow kinematics pre-computed within another used as boundary at inlet smaller 3-D to replicate generated physical flume. A damping zone absorption is arranged end domain before outlet. Numerical results validated against experimental measurements surface horizontal cylinder, demonstrating an agreement. After fixed dynamic study response events. also shown that significantly larger compared forces, secondary load cycle phenomenon becomes included present study.
