The bucket foundation offshore platform with two pillars is introduced in this paper. The structural outline, main dimensions and construction technology of the platform are discussed. The platform has many advantages, such as not needing piles, easy to be constructed, low cost and can be moved and used again. Static and dynamic analyses are carried out by means of space finite element model. The shell elements are used to establish the steel offshore platform and the spring element are used to imitate the interaction between the bucket and the soft soil in the model. Multiple disadvantageous loading conditions of wave and ice are considered in the static structural analysis, and dynamic modes and seismic responses of the platform are also researched in this paper. The results of the anal- ysis show that this kind of platform has enough strength and stability when sub- jected to the loads of wave, ice and seismic. On the basis of the numerical results, some useful advices are presented to optimize the design of the platform.
