| Abstract | Recently, a number of wind turbines are being installed due to the increase of the interest in green energy. Such wind turbines are installed on land or offshore, and most of them are being installed on land because of easy installation. However, because it is possible to get better quality wind in offshore, the request for an offshore wind turbine is increasing and some heavy industries including shipyards is producing various sizes of offshore wind turbines. Because the weight of an offshore wind turbine amounts to hundreds of tons, an offshore floating crane is used for constructing it. Thus, it is very important to secure the safety when the offshore wind turbine is constructed by the floating crane. In this study, we performed a dynamic response simulation of multi-body system to calculate tension acting on wire ropes between the floating crane and the offshore wind turbine when the offshore wind turbine is constructed using the floating crane. For this, we supposed that the motion of the floating crane and the offshore wind turbine has 14-degrees-of-freedom, and there is the interaction by constraints among them. In addition, we considered hydrostatic and hydrodynamic forces which are independent of each other, as external forces acting on the floating crane. The simulation result can be a basis for the verification of the safety of the construction method which the offshore wind turbine is constructed by the floating crane and the application guidance of this method. |
