The fall pipe rock dumping technique is extensively employed to create protection embankments around submarine cables, mitigating distortion and breakage resulting from bottom scouring. During the operation, intricate interactions among pipeline, rocks, water currents can affect stability efficiency of system. This research proposed a method employing fluid–structure interaction analyze between currents. paper begins with design an innovative system presents theoretical analysis applied model testing approach. simulation parameters were determined according geometric, Froude, Strouhal similarity criteria. A thorough numerical was performed investigate hydrodynamic properties rockfall pipeline under interaction. examined settling rocks during rockfall, along forces movements associated deposition process. results show that experienced vortex-induced vibrations (VIVs) caused by ocean operation. maximum velocity throughout process reached 2.2 m/s, final stable 1.5 m/s. These offer critical insights for improving functionality thereby enhancing underwater infrastructure.
