Time-based survival criteria for passenger ro/ro vessels

This paper outlines the study undertaken within the framework of research aiming to address the compound problem of the absolute time available for passenger evacuation on a damaged passenger/RO/RO vessel undergoing large-scale flooding of car deck spaces. Deriving from extensive experimental information and utilizing static equivalent method (SEM) principles, a methodology for predicting ship survival time is proposed that accounts for wave characteristics, water ingress/egress, and vessel survivability. The progress achieved to date is discussed, and aspects needing further investigation are highlighted.
