平台涡激运动易导致立管及系泊系统疲劳损伤，危害其安全、稳定性。平台由于具有较小的纵横比、显著的刚性特征及特有的系泊系统，其涡激运动显示出与立管等细长体涡激振动截然不同的运动特征。文中介绍了FDPSO常采用的特殊升沉补偿装置、多立柱绕流特性及多立柱海洋平台涡激运动的研究进展。鉴于深水多立柱FDPSO涡激运动及稳定性研究是非常复杂的流固耦合问题，文中给出了研究其涡激运动的基本思路和步骤，介绍新型多立柱FDPSO涡激运动的研究方法及现状，为其涡激运动抑制及抑制装置研制提供理论支撑。

Vortex-induced motions of platforms are associated with rise and mooring system′s fatigue damage, which also endanger its security and stability.Due to the small aspect ratio, significant rigid characteristic and its special mooring system of platforms, vortex-induced motions of platforms show different movement characteristics from slender body′s vortex-induced vibration such as riser.The paper mainly includes:the common heave com-pensation devices used in FDPSO, flow characteristics of multi-column and the research progress of vortex-in-duced motions of multi-column platform.Because the fluid-structure interaction problems of vortex-induced mo-tions of multi-column FDPSO in deep water and study of movement stability are really complicated, some basic i-deas and steps for the study of vortex-induced motions are provided in this paper.This paper aims to introduce research methods and the present situation of vortex-induced motions of this new type of multi-column FDPSO, which will provide a theoretical support for the suppression of vortex-induced motions and the development of sup-pression devices.
