Safer by design: using computer simulation to predict the evacuation performance of passenger ships

Abstract

When designing a new passenger ship or modifiying an existing design, how do we ensure that the proposed design is safe from an evacuation point of view? In the building and aviation industries, computer based evacuation models are being used to tackle similar issues. In these industries, the traditonal restrictive prescriptive approach to design is making way for performance based design methodologies using risk assessment and computer simulation. In the maritime industry, ship evacuation models off the promise to quickly and efficiently bring these considerations into the design phase, while the ship is on the drawing board. This paper describes the development of evacuation models with applications to passenger ships and further discusses issues concerning data requirements and validation.
