At the present, probably all simulators make use of mathematical models based on Newton's equations of motion for a body moving in the horizontal plane or , in some cases, in all 6 degrees of freedom. Hydrodynamic forces due to flow around the hull, rudder action and variations in propeller speeds are incorporated based on empirical data derived from model tests or from analysis of full scale data. An increasingly important effect on vessel moving in ports is due to ship-ship interactions or ship-port structure interactions, the last being, for instance, bank suction effects where banks can also be submerged structures or local water depth changes. It is common practice to include such effects based on tabulated interaction data derived from model tests or off-line computations using more or less complicated hydrodynamic models ranging from strip-theory-based interaction models to double-body potential flow using panel models or even full-blown CFD computations. The present contribution concerns the development of a computational procedure for ship-ship and ship-port structure interaction using a double-body potential flow method and its real time application in a maneuvering simulator. The purpose is to be able to dispense with the need to generate interaction data bases and such an approach is expected to increase flexibility with respect to cases studied in the simulator. The method is applicable to multi-body cases involving ships and port structures.
