Description
Protection against fire is one of the pillars of maritime safety. Although the legislation requires compliance with prescriptive regulations of fire prevention, protection and extinction, the concept of “safety equivalence” has enabled substantial innovations in the design of modern passenger ships, where catastrophic consequences may occur. The assessment framework could be improved by introducing a probabilistic formulation (Themelis&Spyrou 2012). This study is an attempt for a step forward, aiming to develop the elements and the structure of a probabilistic attained fire safety index. The probability of fire ignition, the reliability of the suppression systems and the expected loss due to fire development, are key elements contributing to the new index. The index is sensitive to design detail, such as the space layout and the interior design materials used. The distribution of fatalities has been selected as the most appropriate “cost” function. As an application, two adjacent fire zones accommodating passenger spaces will be examined. The “cost” distribution is derived from a batch of fire and evacuation simulations. The method is extendable to address the entire ship.
