EFFECT OF SHALLOW WATER ON THE ADDED MASS FOR THE VERTICAL HULL VIBRATION OF SHIPS: ANALYTICAL CALCULATION USING THE SINGULARITY DISTRIBUTION METHOD

This paper investigates the effects of shallow water on the two- dimensional added mass coefficient C sub v and the three-dimensional correction factor J sub v for the vertical hull vibration of ships. Numerical calculations were performed using the singularity distribution method. These were compared with the results of model experiments involving changes in water depth, and fairly good agreement was obtained. It was found that shallow water had a considerable effect upon C sub v and only a negligible effect upon J sub v. In the final part of the paper, the C sub v coefficients obtained from the numerical calculations for the vertical vibration of bodies with various sectional shapes are presented in chart form. These can be used during the initial stages of ship design to easily estimate added mass in shallow water.
