Abstract  Today's energy scarcity shortage has become a serious problem we are facing now, renewable energy development has become the theme of the moment. 71% of the total area of the Earth's oceans into our line of sight to explore the development, the growing Chinese offshore platform allows us to study marine engineering knowledge more profound. With the development of the offshore oil industry, pillar vortex motion has been widespread concern. In this paper, follow-up study at home and abroad about the column direction of vortex motion, research methods and progress in this field were reviewed and analyzed. In regular waves as a precondition, the impact on the float column swirling motion for research, introduced the related theory, numerical simulation and experimental methods. The numerical simulation of the experiment, the measured three conditions: flow, waves, transverse waves when force fed column, surface pressure, wave and higher data collation, and flow field measurements; comparing Have float (float Fixed) change vortex movement.

This paper mainly complete the following aspects of work：

1、Through contact using school laboratory equipment, laboratory instruments understand the composition, mode of operation experiment.

2、Analyzed at three different conditions according to the experimental results show the different forces and waves of changes.

3、Results comparing the experimental and theoretical data derived formulas obtained.

4、The experimental results obtained with the analytical solutions and numerical simulation results were compared to verify.
