• The authors propose an improved numerical procedure for the estimation of maneuvering forces in ship oblique motion. Based on the slender body theory, the procedure is developed after critical review of various flow separation models. The improvements mainly concentrate on the force and flow predictions near the ship ends. The theoretical solution of the flow around a prolate ellipsoid is applied to correct the force near the bow, and a discrete vortex model is adopted to simulate the separation layer emerging from the stern edge. Using the experimental hydrodynamic data of SR221 ship series (9 ships) and MPR ship series (6 ships), the authors investigate the performance of proposed numerical procedure. It is concluded that the proposed numerical procedure predicts the relative changes on hydrodynamic force, due to the changes of hull form parameters, with more confidence than to predict the absolutely correct values of ship maneuvering hydrodynamic force. The Type Ship approach, proposed as a method to combine experimental and numerical approaches for the estimation of hull hydrodynamic properties, is a rational way to use experimental (database) data of prototype ships for the design of a new ship. The authors point out the key components of the Type Ship approach: existence of database data, availability of a numerical procedure for the estimation the changes of hull forces and a method to assess the difference of hull forms in view of the hydrodynamic performance.
