Platform with rocking column is a new style structural system which can effectively control the dynamic responses of the offshore platform under ice loads. Combined with energy dissipation devices, the new system can have a good energy dissipation ability. This paper optimizes the schemes to research the influence of number and location of link rods and the diameter of rocking column with ANSYS software. The results show that link rods and rocking column have great influence on vibration control effect. The more the link rods and larger the rocking column are, the better vibration control effect will be. Considering the economy of structure and contact area of rocking column and marine, scheme three, four connecting rods and 360 mm rocking column, has been chosen. 1∶10 scale models, offshore platform and platform with rocking column, have been designed and produced on the base of JZ20-2. The results show that the offshore platform with rocking column is an effective way to reduce vibration.
