Abstract

This paper proposes a large-scale integrated HDPE floating block structure. Utilizing the Volume of Fluid （VOF） method, a numerical wave tank is constructed, and a hydrodynamic model of the floating structure is developed by coupling computational fluid dynamics （CFD） with rigid body dynamics. The study investigates the motion response and mooring force characteristics of the floating structure under inshore sea conditions. The results indicate that the maximum surge, maximum heave, X-direction velocity, and Z-direction velocity of the floating structure are positively correlated with wave height. The maximum surge and maximum heave of the floating structure increase with an increase in the wave period. Higher wave heights and shorter wave periods lead to greater fluctuations and the higher amplitudes of the mooring forces experienced by the floating structure.

Key words
