Abstract

This study employs the Smoothed Particle Hydrodynamics (SPH) method to develop a computational fluid dynamics (CFD) model for analyzing the interaction between rogue waves and mooring systems. Four floating body configurations are investigated: (1) dual rectangular prisms, (2) rectangular prism–sphere composites, (3) sphere–rectangular prism composites, and (4) dual spheres. These configurations are systematically evaluated under varying mooring conditions to assess their hydrodynamic performance and wave attenuation capabilities. The model accurately captures the complex fluid–structure interaction dynamics between moored floating breakwaters and incident wave fields. Among the configurations, the dual rectangular prism system demonstrates superior performance in both wave dissipation and mooring force reduction. Under conditions involving dual wave makers, the influence of floating body shape and number on wave height is found to be minimal. However, dual-body arrangements consistently outperform single-body setups in terms of both energy dissipation and structural stability. From a cost-efficiency perspective, the configuration comprising two rectangular prisms connected via a single mooring system offers significant advantages in material usage and deployment feasibility.
