Hussein, A.W. and Guedes Soares, C. (2009), “Ultimate Strength of Intact and Damaged Bulk Carriers”, Proceedings of the 13th Congress of International Maritime Association of Mediterranean (IMAM´09), 12-15 October, Istanbul, Turkey

This paper studies the ultimate strength of damage bulk carriers considering different scenarios of collision and different sizes of the damage. Four bulk carriers with different cross sections are considered. Damage is assumed to take place at the sides, collision, and at the bottom, grounding. Different damage sizes and locations are applied to calculate the minimum ultimate strength which might be reached due to damage. The ultimate capacity is calculated using a developed code, which applies progressive collapse method and the damage, is simulated by removing the damaged part from the midship section. Simple equations, which are function of damage size, are proposed to estimate the loss in the strength and section modulus after damage.
