Estimation of propeller-induced excitation forces is discussed and a comparison between computed and measured propeller-induced pressure distributions for an 8000/12000 dwt ro/ro vessel are shown. Diagrams for axial wake of model and full-scale ship are also compared. Vibration calculations are described, and modelling aspects, and the effect of the surrounding water are dealt with. The measurement of vibrations using a measuring system developed in the Finnish VTT Ship Laboratory is explained. An exciter test system is used. Prediction of the vibration level and trouble-shooting vibration measurements are also dealt with.
