This thesis presents a comparison of added mass modeling techniques that may be used to determine the the vibration response characteristics of ships in water. The mathematical treatment of added mass is reviewed, and a number of numerical approaches are discussed. Experiments to determine the natural frequencies of a ship model in air and in water were performed and were compared with the results obtained from the numerical approaches. It will be shown in this thesis that the use of modal analysis to predict ship vibration responses in water is a satisfactory and less time consuming alternative to a full eigenvalue solution. === Applied Science, Faculty of === Mechanical Engineering, Department of === Graduate
