最近，由于人们对绿色能源的兴趣增加，一批风力发电机正在安装中。这类风力涡轮机安装在陆地或海上，由于安装方便，大多数都安装在陆地上。然而，由于在海上获得更好的风力质量是可能的，对海上风力涡轮机的需求正在增加，包括造船厂在内的一些重工业正在生产不同尺寸的海上风力涡轮机。海上风电机组的建造使用浮吊，因为它的重量达数百吨。因此，确保施工过程中的安全是非常重要的。本文对浮吊悬挂的海上风力机进行了动力响应仿真。为此，我们假设浮吊和风力机的运动具有14个自由度，并且它们之间存在约束相互作用。此外，将相互独立的静水动力和水动力视为作用在浮式起重机上的外力。仿真结果可用于验证海上风电机组浮吊施工方法的安全性和该方法的应用指导。
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 wind quality in offshore, the request for an offshore wind turbine is increasing and some heavy industries including shipyards are producing different sizes of offshore wind turbines. A floating crane is used for constructing the offshore wind turbine because its weight amounts to several hundred tons. Thus, it is very important to secure the safety during the construction. In this study, a dynamic response simulation of the offshore wind turbine suspended by the floating crane is performed. For this, we supposed that the motion of the floating crane and the wind turbine has 14 degrees of freedom, and there is the interaction by constraints among them. In addition, hydrostatic and hydrodynamic forces which are independent of each other are considered as external forces acting on the floating crane. The simulation result can be used 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.
