Steel sandwich plate system (SPS) possesses the advantages of light weight, high strength and can effectively improve the crashworthiness of ship. By using the ANSYS/LS-DYNA software and composite materials model , this paper simulates and calculates the dynamic process of a FPSO hit by a 5000DWT work ship in the lateral direction, studies the influence of SPS parameters on the crashworthiness of the FPSO broadside. Calculation results show that the crashworthiness of the FPSO broadside is improved by using sandwich plate system.
