This report presents a comparison of added mass modelling techniques that may be used to determine the vibration response characteristics of ships in water. The mathematical treatment of added mass is reviewed, and a number of numerical approaches are discussed, including finite element & boundary element methods and modal analysis. Examples are presented of the different numerical approaches when applied to a ship model and numerical results for the natural frequencies are compared with experimentally determined values.

Knowledge of added body masses that interact with fluid is necessary in various research and applied tasks of hydro- and aeromechanics: steady and unsteady motion of rigid bodies, total vibration of bodies in fluid, local vibration of the external plating of different structures. This reference book contains data on added masses of ships and various ship and marine engineering structures. Also theoretical and experimental methods for determining added masses of these objects are described. A major part of the material is presented in the format of final formulas and plots which are ready for practical use. The book summarises all key material that was published in both Russian and English-language literature. This volume is intended for technical specialists of shipbuilding and related industries. The author is one of the leading Russian experts in the area of ship hydrodynamics.

Consists largely of abstracts of articles and papers of interest to shipbuilders, ship owners and marine engineers.
