Preostala čvrstoća slučajno oštećenog tankera za prijevoz nafte

The aim of this paper is to develop probabilistic model of the reduction of the residual ultimate strength of oil tanker following random grounding and collision damages. 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 in the case of grounding is calculated using concept of grounding damage index (GDI), assuming grounding on the conically shaped rock. Progressive collapse analysis (PCA) using MARS software is employed for residual strength assessment in case of collision, employing damage box concept. Influence of rotation of the neutral axis is approximately taken into account for collision damage. Probability distributions are intended for structural reliability assessment of damaged oil tanker.
