Open publisher page 5 citations

Abstract

Regression analyses were carried out, based on data from full-scale measurements of pressure amplitudes on the hull and vibrations of the superstructure on 72 ships. Model wake field data from the ships were included in the analysis. The investigations showed close relations between; pressure fluctuations on the hull (blade and 2 x blade frequency) propeller clearances propeller design wake field aft draft superstructure vibration level (blade frequency) hull surface forces aft draft.
