Introduced the structure characteristics of the locating crash FRP floating pontoon is introduced. Based on the platform ANSYS/LS-DYNA software, the nonlinear numerical simulation was carried out for a 2000 DWT bulk cargo ship with the floating pontoon considering the direction and 8° oblique collision. The process of energy dissipation and the impact force attention schedule and the collision zone of struc-tural deformation and damage of the failure process were obtained. It provided the theoretical basis for the engineering design and experiment.
