Computer Simulation of Risk Assessment for a Ship with a Novel Arrangement of Internal Spaces in Damaged Condition

Abstract

The paper presents some results regarding the risk assessment for a ship with the novel arrangement of internal spaces, at the preliminary stage of design. The objective of the research is to introduce a method for the multi-objective and multi-parametric-variation investigations to achieve the required and optimal levels of a ship safety in damaged condition The method is a parametric-risk-based one. It uses the elements of knowledge following from the formal safety assessment (FSA) methodology, ship hydromechanics and ship safety. A computational model has been developed and it works as a kind of database. It consists of e few modules: design requirements, constraints and criteria, ship and environment definition, hazard identification, hazard and risk assessment, modification of design and decisions on safety. The results follow from the computer simulation of the risk assessment (assessment of the ship safety in damaged condition) for a container and general cargo vessels with a novel arrangement of internal spaces anticipated at the preliminary stage of design The practical remarks regarding the method, computational model and preliminary results are given.
