HYDRAULIC MODEL EXPERIMENT ON THE PROCESS OF INSTALLING A BATCH OF WIND TURBINES ON THE SPAR TYPE FLOATING STRUCTURE

Abstract

 As demand for renewable energy increases, there is an urgent need to identify issues related to the construction of floating offshore wind farms. In the construction of spar-type floating wind farms, a construction method in which wind turbine components (towers, blades, and nacelles) are suspended from a hoist vessel and mounted on a spar-type floating structure is considered. To determine whether work can be performed during such construction and to calculate the operation rate, it is essential to understand the amount of motion under conditions where multiple floating structures interfere with each other. In view of the above background, the purpose of this study is to contribute to the construction planning of future floating offshore wind turbine farms. Hydraulic model experiments were conducted to simulate the three-stage process of mounting a wind turbine suspended from a hoist vessel onto a spar-type floating structure to determine the amount of motion of each structure and the tension acting on the suspension line, and some considerations were made.
