The potential of floating wind-aquaculture platform (FWAP) to properly utilize maritime space and its resources is attracting the attention of engineering and educational communities. Nevertheless, those platforms combine the hydrodynamics with aquaculture system. This study aims to assess how three distinct hydrodynamic dampening additives perform and how random environmental stresses affect the dynamic responsiveness of a floating wind-aquaculture platform. A couple of hydrodynamic force technique is implemented. First, numerical tests of the platform’s decay and forced oscillation in still water are completed by ANSYS Aqwa. These tests are conducted by simulating the dynamic behaviour under various combinations of hydrodynamic forces, such as the varying stochastic wave excitation forces on the floating frame. The dominating modes in the low- and wave-frequency ranges are the hydrodynamic damping of the floating body. The turbulent wave pressures are the two environmental load additives that dominate the surge route within the low-frequency variety. The primary-order wave force is primarily responsible for the platform’s dynamic response in the wave-frequency range. Fish nets have very no effect on wave-frequency motion, but they can reduce low-frequency motion.
