外文摘要：To investigate the characteristics of the semi-submersible against the extreme waves, a model of solitary waves interaction with the semi-submersible was established based on the meshless SPH method and Rayleigh's theory. The wave surface and wave load results of the SPH model for an interaction test case between solitary waves and partially submerged rectangular obstacles are in good agreement with the OpenFOAM results accompanying with maximum relative errors 3.4%. The calculated results of a semi-submersible against the solitary waves show that the overtopping occurs with the wave height H0 > 0.2 m for the unsubmerged ratio 0.33, while the wave overtopping decreases with the increase of water depth. The WLA in the z direction is quite larger than x direction with maximum value of 0.705, 0.761, and 0.799 for water depth 1 m, 2 m, and 3 m. The transmission coefficient decreases with the increase of wave height, while it increases with the increase of water depth. The maximum values are 0.734, 1.040 and 1.085, respectively, obtained at H0 = 0.025 m. The reflection coefficient reaches peak with the maximum value 0.685, 0.284, and 0.215 at wave height H0 = 0.2 m. ? 2023, The Authors. All rights reserved.
