Abstract
Collapsing cavities on or in the vicinity of ship propeller blades cause pressure pulses which excite the hull structure above the propeller. Inevitably, this leads to higher noise and vibration levels in public spaces on board. Because of more demanding comfort criteria the prediction of propeller-induced hull pressure pulses is still an important issue in ship design.
In this paper some recent developments are presented in the prediction of hull excitation forces either through model basin tests, by computational means, or through feedback obtained from sea trials. Special attention is paid to ongoing European projects and other cooperative research initiatives that are considered helpful in improving prediction techniques.
