The finite element model of the DP semi-submersible platform floating structure is created by ANSYS software.Based on the method of fluid—structure coupling, the dynamic properties of the structure is determined.By Considering the particularity of the dynamic position propulsion device and operating condition,calculating the excitation load by empirical formulas,the vibration response of structure is analyzed.Some significative conclusions,which can provide the reference for designing and researching the DP semi-submersible platform floating structure,are drawn out.
