Description

<p>In the construction of floating offshore wind turbines in Japan, floating crane ships have been used. However, they are prone to swaying due to waves and wind, so there is a big risk especially when working in the open sea. In addition, Japan has little experience in the construction of offshore wind power generation, and it is not possible to ensure safety based on empirical rules alone. From these facts, it is considered that there is a high need for preliminary examination of construction by simulation in order to reduce risks during construction. Also, standard method for dynamic simulation of marine operations has not yet been established. Thus, in this paper, we attempt to develop safety evaluation method based on dynamic simulation of marine operations using a floating crane. As a first step, we measured motion of a nacelle during construction of a 2.1 MW spar-type floating offshore wind turbine. Then, we compared the motion with numerical simulation by OrcaFlex.</p>
