摘要
参照三浮筒式OC4半潜式风机基础,设计了四浮筒式浮式风机基础.建立三浮筒式OC4半潜式风机基础与四浮筒式浮式风机基础水动力模型,利用AQWA软件分析四浮筒式浮式风机基础相关水动力参数,并将四浮筒式浮式风机基础与三浮筒式OC4半潜式风机基础进行不同工况下的时域分析对比,探究两者间性能差异.结果表明,四浮筒式浮式风机基础具有良好的水动力性能,相较于三浮筒式OC4半潜式风机基础,其在纵荡、横荡、纵摇、艏摇4个自由度方向上的运动响应以及缆绳张力方面存在优势.
Abstract
Based on the three-buoy OC4 semi-submersible wind turbine foundation,a four-buoy floating wind turbine foundation is designed.Water dynamic models for both the three-buoy OC4 and four-buoy floating foundations are established.Using AQWA software,relevant hydrodynamic parameters of the four-buoy floating foundation are analyzed.A comparison of the performance of the four-buoy floating foundation and the three-buoy OC4 foundation under different conditions is conducted through time-domain analysis.The study investigates the performance differences between the three-buoy OC4 and four-buoy floating foundations.Results indicate that the four-buoy floating wind turbine foundation exhibits good hydrodynamic performance,with advantages over the three-buoy OC4 foundation in terms of motion response in heave,sway,pitch,and yaw directions,as well as cable tension.
