Protective Effect Of An Ice-Breaking Structure On Offshore Structures In Shallow Waters, Ji-Wu Dong, Zhi-Jun Li, Xiang-Peng Kong, Xiao-Dong Liang
Journal of Marine Science and Technology
In this study, an ice-breaking structure (IBS) was designed to break large ice floes into small fragments through flexural failure predominantly for protecting offshore structures in shallow waters. The protective effect of the IBS on a vertical isolated cylindrical pile (ICP), which was examined through the model tests of the crushing ice loads and collision forces on the ICP from ice pieces broken with the IBS under identical conditions, was evaluated by obtaining the relative difference between the maximum values of the horizontal crushing forces and collision loads on the ICP. The results indicated a notable protective effect of the …

This study conducted a model test of 1:100 model scale of a semi-submersible platform with a 1500 m full-depth mooring system in the Joint Laboratory of Wind Tunnel & Wave Flume at Harbin Institute of Technology. A truncated mooring system of 400 m water depth was designed based on the static equivalent principle. The semi-submersible platform was tested under regular wave excitation periods that ranged from 10 s to 45 s and one year of irregular wave conditions in the South China Sea. The results validated the feasibility of using numerical simulation in the motions calculation of semisubmersible platform and …
