ABSTRACT
The performance of a struck ship’s hull is quantified in terms of the shape and size of the damage opening in the side-shell structure, and the division of energy absorption between the striking and struck ships. This chapter presents a motivation to the RoPax ship used as the struck case study vessel. It provides the parametric study of a ship-ship collision using the Finite Element software Abaqus/Explicit. The effects of ship-ship collision damage and progressive deterioration due to corrosion of a struck ship’s hull are studied numerically in a crashworthiness assessment. Performance assessment of the crashworthiness of corroded ship hulls requires a combination of damage opening and energy analyses. A lot of more energy is accumulated as internal energy in the ship structures when the corrosion margins of the struck vessel is removed, and the friction conditions are changed to represent corroded surfaces.
