This paper presents an analysis of the side hull in marine steel structures under accidental collision phenomena. The type of side collision considered in this work is where the striking ship penetrates the struck ship. First, the configuration of the collision phenomenon is defined, including the ship geometry, mechanical properties of the material, and applied parameters. The collision scenarios are built by applying external dynamic parameters, including target location and striking velocity. Impact locations are determined on three different regions of the struck ship’s side hull: the fore-end, middle-hull, and after-end regions. These are discussed, followed by results based on the applied velocity. Second, the tendency of the collision energy is evaluated to observe the structural behaviour on the struck ship’s side hull during penetration by the striking ship. Progressive failure is summarised based on the results of two parameters, and f the material model is confirmed by comparing the collision energy with pioneering work on ship collision.
