This paper presents a review of current risk-based design as applied to passenger ship safety and highlights future developments. Emphasis is placed on demonstrating the considerable potential offered to the marine industry by embracing innovation, in terms of routine utilization in the ship design process of scientific and technological breakthroughs, to contain risk.The paper highlights the integration of first-principles simulation tools for flooding and fire (PROTEUS and LESS-FIRE, respectively) into an advanced EVI (evacuation model environment) and presents a workable model for containing risk in passenger ships with regard to loss of human life. The integration of such tools allows for an explicit and direct evaluation of ship and human life safety in any given flooding and/or fire incident/accident scenario. This type of capability is essential if a 'holistic approach' for ship design is to be adopted, particularly in relation to large passenger ships. This approach entails that large passenger ships must be able to withstand a stipulated damage (extent of damage) threshold and still safely return to port under its own power. Even if the casualty threshold is exceeded, a.ship is to remain habitable for a minimum time (3 hours) to allow for safe and orderly abandonment. The above reflects the trends toward goal-based standards and highlights the merits of a risk-based design methodology. This is particularly useful when dealing with innovative ship design concepts and alternative design and arrangements. In such cases, quantitative risk analysis is the only reliable route to ensure that an appropriate level of safety (equivalent to an acceptably low level of risk) and the set safety goals (e.g., safe area) are achieved.
