Abstract

<p>Firstly, risk analysis for loss of life was carried out based on IHS Fairplay Casualty and Ship databases. Passenger/Cruise ships and RoPax ships 1,000 GT or above were focused in this study. The risk analysis was conducted for ships built before 1990 and for ships built in or after 1990. The results show that the risk of Passenger/Cruise ships and RoPax ships is reduced. Next, risk evaluation was conducted by using ALARP borders on F-N diagram. The results show that F-N curves of Passenger/Cruise built before 1990 and built in or after 1990 ships and RoPax built in or after 1990 ships locate within the ALARP regions. On the other hand, F-N curve of RoPax built before 1990 ships locates within Intolerable region. In this paper, sub-groups have priorities in considering risk control options are considered and the reason that F-N curve of RoPax built before 1990 ships locates within Intolerable region is discussed.</p>
