Abstract
The methodology for the structural reliability assessment of oil tanker damaged in collision and grounding accidents is proposed in the paper. The approach is consistent with International Maritime Organization (IMO) structural reliability assessment of intact oil tankers. The main extension of the structural reliability analysis of the intact ship is that the loss of the ultimate longitudinal strength and the increase of the still water bending moment in damaged condition are considered as random variables. The probability distributions of these random variables are defined based on damage parameters proposed by IMO. The methodology is applied on the example of the Aframax oil tanker resulting in the failure probabilities comparable to the other similar studies. The advantages of the presented approach are its simplicity and consistency with IMO rec-ommendations. Sensitivity analysis is performed that enables identification of the most important parameters for structural safety of damaged ships. The methodology may efficiently be applied in the risk assessment studies of the maritime transportation as well as for calibration of partial safety factors in the ship structural rules.
