A mechanics model is presented for the static and dynamic analysis of ship-platform collision system, and the static equivalent intensity analysis is applied to the damaged X diagonal brace member of platform structure. In the course of dynamic elastic-plastic analysis of offshore platforms, the added mass coefficients for the seawater dynamic effect and the structure-pile-soil mutual interaction are considered in the analysis of computational model. The nonlinear springs are introduced for the simulation of the force-deflection relationship of the local indentation for the damaged X diagonal brace. The curve of indentation deformation of the damaged member and different collision contact time is simulated under the velocity of ship being assumed. According to the curve, the formula of indentation deformation of the damaged member and different collision contact time is obtained to determine the maximum impact load.
