The paper presents identification of main errors which may occur during dynamic analysisof ship’s hull and superstructure. The investigation was realized on the basis of calculations of natural and forced vibrations. The analysis was performed for cargo ships with typical propulsion system. Multi-variant computations of ship vibration were carried out with the use of previously identified excitation forces. A computation method for excited vibrationsof ship hull and superstructure was developed
