The paper presents identification of main excitation forces of vibrations of ship hull and itssuperstructure, as well as investigation of influence of the analyzed excitation on shipvibration level. The following excitation forces were analyzed: dynamic pressure on thetransom deck, propeller-generated hydrodynamic forces, as well as internal and externalengine-generated forces. Rigidity and attenuation characteristics of lubricating oil filmwere taken into account in the analysis of the excitations transmitted by the propulsionsystem bearings (stern tube bearing, intermediate bearing, engine’s main and thrust bea-rings). The dynamic characteristics of ship’s power transmission system were also taken into account.Results of the analyzes were verified by comparing results of the computations and measurements
