Operability and Sea worthiness Analysis of Passenger Ship using Motion Simulation

Abstract

The disturbance of external forces such as wave force will affect the comfort and safety of the crew and the passengers of a vessel. The ship’s motion response is a paramount parameter that must be considered to be considered during the ship feasibility design. This paper provides an analysis of three responses of ship motions namely heaving, rolling and pitching. The operational scenarios include full load with three ship speeds of 8, 10, 12 knots and three headings of 0°, 90°, and 180°.The variation of the wave height is significant and the zero up crossing wave period is based on the shipping data and the route of the vessel in accordance with the sea state. The simulations were performed using the MaxSurf Motions Advance software. The simulation results show that the percentage of ship operability based on seakeeping criteria is 86.58% operable and 13.42% downtime. The comfort level on the passenger vessel presented by the value of Motion Sickness Incidence and found to be less than 10 SM for the operational wave height permitted and safe sailing vessels in the waters of Java Island.
