Abstract: In this paper an outline is given of the fundamentals of measurements on hydroelastic structures. In particular the difficulties as encountered in hull pressure measurements on a shipmodel are reported. An estimate is made of the errors that may occur in the model measurement of propeller excited vibratory hull pressures and a method is given to correct the measured quantities, influenced by the elastic response of the hull of the model, by means of a dynamic calibration.
