'Highest Comfort Class' Design for 'M/S Color Fantasy', The World's Largest ever Cruise-Liner with Car-Deck

摘要

A wide range of theoretical calculations, model tests and full-scale measurements were undertaken to meet the design challenge presented by Color Fantasy, the world's largest cruise-ship with car-decks. Achieving the highest comfort standard in the a la carte restaurant in the stern of the vessel proved to be the most challenging.Optimisation of the hull form for different operating conditions and the development of the "Wave Damping Afterbody" were conducted using a number of potential flow CFD tools. Several appendage designs were investigated to determine the lowest resistance and the best wake field to the propellers.The challenge of designing a propeller to meet the requirements for the different operational modes specified for the ship is described. To fulfil DNV Comfort Class 1, propeller cavitation, in particular the tip vortex, must be kept to a minimum. Results from calculations, model and full-scale tests are also presented.Open-mindedness and good co-operation between the shipyard, consultants, classification society, model basin, propeller maker and client, was vitally important in achieving the standard.The quality of the whole design was validated by means of model experiments. The paper compares calculations, model test data and full-scale measurements.
