Hull vibrations of the cargo-liner “Koudekerk” 1

For the cargoliner “Koudekerk” some natural frequencies of the horizontal and vertical vibration of her hull and the pertinent modal profiles, were determined. The hull was excited by a mechanical exciter. The vibration mode of a section of the double bottom was investigated at two natural frequencies of the hull. This report also compares the results of measurements with those of some calculations of mechanical impedance.
