Probabilistic model of ultimate strength reduction of grounded ship

The aim of this paper is to develop probabilistic model of the reduction of the bending moment capacity of oil tanker following grounding accident. The approach is based on Monte Carlo (MC) simulation using probability distributions of damage parameters proposed by International Maritime Organization (IMO) . Reduction of ultimate strength is calculated by recently developed regression equations using concept of grounding damage index (GDI). Case study is presented for aframax tanker resulting in the Weibull distribution fitted to the histogram obtained by MC simulation. Results of the study are useful for structural reliability assessment of damaged ships and also for conceptual studies of different structural configurations as demonstrated in the paper.
