AN APPROXIMATE CALCULATION OF MANEUVERING INTERACTION FORCES BETWEEN TWO SHIPS

This article deals with an approximate calculation of hydrodynamic forces generated by interactions between two ships that are moving along parallel courses at the same velocity. Hydrodynamic interactions between ships and a bank wall are also examined. The method assumes a rigid free surface and infinite water depth. The calculation is based on the linearized thin-wing theory, using sources distributed over the center plane to represent the thickness effects of the two ships' bodies. A correction factor for equivalent distance between a ship and a bank wall is introduced to modify the ship breadth effect on the interaction forces, and the value of the factor is determined experimentally. The study makes it clear that the correction factor is almost constant, regardless of ship breadth and the separation distance.
