A PRACTICAL PREDICTION METHOD OF THE LINEAR DAMPING DERIVATIVES FOR SHIPS MOVING OBLIQUELY IN SHALLOW WATER

Based on the calculation of added mass of various sections of the ship's hull, the linear damping derivatives for ships moving obliquely in shallow water are calculated using slender body theory. The viscous influence is suitably accounted for in the calculation. The calculated results show good agreement with existing experimental data and are closer to the experimental data than those of some other slender body approaches. Due to its simplicity, the prediction method given in this paper can be easily used to predict the linear damping derivatives for ships moving obliquely in shallow water in the preliminary ship design stage.
