Abstract Floating breakwaters are different with fixed ones and suitable for the deep sea situation. In the past few years, box-type floating breakwaters have been studied and improved by experimental and numerical analysis extensively. In this paper, a new winged box-type floating breakwater is proposed and Smoothed Particle Hydrodynamics is applied to simulate the nonlinear interactions between the waves and winged box-type floating breakwaters. The performance of the non-winged ones and winged ones are studied. The motions of the proposed floating breakwaters are also studied to understand the effects of the protruding plates. The velocity fields of the surrounding water are examined to reveal the mechanism of the wave energy dissipation. The last but not least, the best locations for adding protruding plates are identified.
