Numerical simulation of seakeeping performance of deep water semi-submersible platforms under the combined action of wind and wave
This article investigates the seakeeping performance of a deep water semi-submersible platform under the combined action of wind and waves through numerical simulation methods.This method establishes a wind speed and wave coherence function model,and uses this model to obtain the relationship between wind speed and waves under different op-erating conditions of the current deep-water semi-submersible platform.Then,the wave and wind forces of the deep-water semi-submersible platform under the combined action of wind and waves are calculated.Based on these two values,a numer-ical simulation model for the seakeeping performance of the deep-water semi-submersible platform is constructed,and the seakeeping performance of the deep-water semi-submersible platform under the combined action of wind and waves is simu-lated under different conditions.The experimental results show that this method can simulate the sway and heave values of deep water semi-submersible platforms under the combined action of wind and waves at different wave periods.When the wave period is small,the sway and heave values are also small,and the seakeeping ability of deep water semi-submersible platforms is strong;The larger the wind wave angle,the greater the vertical bending moment value of the deep water semi-submersible platform at the same wave period,and the smaller its wave resistance.
