Numerical Research on the Hydrodynamic Characteristics of the T-Shaped Floating Breakwater

In our report, in order to improve the abilities of floating breakwater to protect coasts, harbors and marine structures from wave attacks, a novel type of T-shaped floating breakwater is proposed. Firstly, the numerical simulation method was used to establish a numerical model of the interaction between waves and T-shaped floating breakwater; Secondly, the effects of the draft depth, the height of vertical plate, and the pontoon width on the transmission coefficient, mooring force, and wave pressure distribution of T-shaped floating breakwater under waves action, were analyzed. The results indicated that when the relative width and vertical plate height of breakwater are 0.48 and 0.35 respectively, compared with that there are no vertical plate, the wave attenuation performance can be improved by 76%, and the mooring force can be reduced.
