Abstract
In this study, a floating crane vessel with a wind turbine rotor is analyzed using multibody dynamics theory. The analytical model is produced for simulation of the marine operation during the offshore installation of the wind turbine rotor to the nacelle. Comparison of the results of the dynamic analysis with the measured data of the floating crane vessel has shown that the analytical results can predict well the motions in roll and pitch directions but underestimate the motion in yaw direction. The complex behavior of the rotor motion is observed from the analytical results in several incident wave cases. Finally, the availability ratio of the marine operation is assessed based on the analytical results. The effect of number of mooring lines to the availability ratio is also examined.
