The objective of this research is to develop a reliability-based procedure for the ship operators to make the immediate repair actions by evaluating the effects of the damage on the safety of the ship using residual strength assessment procedure. In this study, a procedure has been developed to assess structural integrity of damaged ships. The procedure consists of four steps: (1) Identify the location and size of the openings; (2) Calculate the still water bending moment and wave-induced loadings including vertical bending moment, horizontal bending moment and torsion; (3) Calculate the ultimate strength of the damaged cross-section considering the interaction of vertical bending moment, horizontal bending moment and torsion; (4) Assess the structural integrity by deterministic and probabilistic approaches. The state of the art of the methods for predicting environmental loads and assessing the structural safety has been reviewed. The developed procedure is applied to a sample vessel, HULL5415, to demonstrate the applicability of the proposed procedure. Overall the developed procedure and the methods are working well.
