Sažetak
The procedure is illustrated in the case of a 49500 dwt Chemicals and Oil Products Carrier. Vibration calculation includes estimation of propeller excitation forces and ship response due to both propeller and engine excitation. Ship hull vibrations are analysed by 1D FEM model, while ship structure vibrations by a combined 3D and 1D FEM model of the aftbody and remaining hull part, respectively. Ballast condition and full ship are considered in combination with unsupported and supported engine. The obtained results show that the engine excited vibrations are rather high, and therefore installation of vibration compensator is recommended. Ship vibrations are measured by Brodarski Institute – Zagreb during the sea trial. Very good agreement between calculated and measured ship hull natural frequencies is achieved.
