Capsizing Probability of an Indonesian RoRo Passenger Ship in Irregular Beam Seas (Second Report)

In our first report, we presented a methodology for determining the critical metecentric height of an Indonesia RoRo passenger ship in the light of the annual capsizing probability calculated with piece-wise linear mathematical model and wave statistics. The second report follows the methodology in the first report, and provides more realistic outcomes by making use of the ship roll data from the model experiments and corrected wave statistics. As a result, it is demonstrated that the annual capsizing probability of the Indonesian RoRo passenger ship with side openings of the RoRo space almost coincides with the actual capsizing rate taken from the casualty statistics in Indonesian water areas, and can be drastically reduced by closing the side openings.
