THEORETICAL STUDY ON MANOEUVRABILITY OF SHIPS

A theoretical method to calculate the flow fields and hydrodynamic forces of a ship in steady turning manoeuvres is presented. The double model assumption is adopted for the free surface effect. The flow around a hull and the hydrodynamic forces are calculated by Morino's surface panel method. The simplified propeller theory for a propeller and the surface panel method for a rudder are applied to a propeller-rudder system (PRS) which is a propulsor producing thrust and lateral forces. The mutual interaction between the hull and the PRS can be calculated considering the induced velocity due to the other. The approximate procedure using interaction factors to estimate hydrodynamic forces acting on a ship is introduced from a practical point of view. The calculated results are compared with experimental data. The methods adopted are shown to be effective.
