A comprehensive captive model test program was carried out to improve the formulation of ship-ship interaction forces and moments in the mathematical model of a ship manoeuvring simulator. The test equipment, the experimental program and a selection of preliminary results is reviewed. An analysis, based on the magnitude and position of the extreme values for the longitudinal and lateral force components and the yaw moment, yields a formulation for the time history of interaction forces for each particular combination of ship models as a function of drafts, water depth, speeds and lateral distance. As such an approach is not practical for time histories characterised by more than four extremes, which may be the case if the target ship's length is significantly greater than the own ship's length, alternative formulations are suggested as well.
