Hussein, A.W. and Guedes Soares, C., (2011) , “Reliability assessment of intact and damaged bulk carriers”, Advances in Marine Structures, 2011, Guedes Soares & Fricke (eds), Taylor & Francis Group, London,UK, pp: 679-690
This paper studies the reliability of two single hull bulk carriers subjected to damage. Two damage scenarios are assumed, collision at side and grounding at the bottom. The ultimate strength is calculated using the Progressive Collapse Method. The reliability is assessed for both damage scenarios and compared with the intact ship reliability. In the damaged condition, the ship should not operate with a very high speed, and she will avoid very rough sea. Therefore, the related wave-induced bending moment may be smaller than that for the normal design extreme condition. On the other hand, damage to the vessel’s hull may result in the ingress of water and for fluid cargoes cargo out-flow may occur which will result in a change of the loading condition and a variation to the still water bending moment. The reliability is assessed and sensitivity analysis is performed to study the importance of the variables after and before damage.
