The ship side collision with ice is simulated by using the finite element numerical simulation method, and the calculation results after collision are analyzed in qualitative and quantitative method. Then the condition of structural damage of ship’s side, the change of energy, and the condition of stress and plastic strain are obtained. In the end, the paper summarizes the plastic deformation on the structure of the side for a variety of operating modes, and the method of calculating the ship safety speed in ice water is presented.
