Abstract: Supposing that the ice thickness is a random variance conforming to the Logarithm Gauss distribution and taking into consideration the variation of ice rigidity, crushing length and clearance stress with ice thickness, the stochastic model for the dynamic interaction between ice and offshore structure is set up. A simplified finite element model of actual offshore platform in Bohai Sea is constructed for computing the structure response. The influence of ice velocity and ice thickness on the response displacement of the platform is discussed.
