• A method was developed to calculate the hydrodynamic forces acting on a turning ship taking the interaction effects among hull, rudder and propeller into account. The lifting surface theory for expressing the hull and rudder, and the simple sink propeller model are adopted under the assumption of the thin ship. A wake vortex model of a turning ship was proposed for accurate evaluation of the hydrodynamic forces. Calculations were made of the hydrodynamic forces acting on the turning and obliquely moving ship with steering by use of the present method. And the following interaction effects among the hull, rudder and propeller were investigated theoretically: (1) propeller effect on hydrodynamic derivatives of ship hull, (2) propeller effect on hull-rudder interaction coefficients, (3) effect of turning motions on hull-rudder interaction coefficients, (4) effect of turning motions on thrust deduction factor. As a result, it was found that the present method is useful for a better understanding of the hydrodynamic interactions among the hull, rudder and propeller for the turning ship.
