摘　　要：为了提升海上风机“先桩法”导管架基础的施工效率,减少安全事故发生的可能性,研发了海上风机基础定位吊装系统,该系统包含:形象进度模块、三维模型展示模块、视频监控模块、基础结构物监测模块,通过对导向平台及导管架(后统称为结构物)上传感器实时传输数据的相关理论计算及可视化,实现对风机基础吊装施工全过程的定位、监控,以指导施工过程有序、快速地进行。该系统成功运用于粤电阳江沙扒海上风电工程项目。吊装过程中结构物平台上的倾角角度始终在3°以内且最终达到稳定时小于0.2°,满足倾斜度0.5%以内的要求;GNSS定位数据异常值较少,不影响整体判断结构物的位置,且最终GNSS测值均趋于目标坐标。应用结果表明:在该系统辅助下,基础结构物吊装过程平稳且高效,能够实现基础结构物吊装厘米级定位精度。In order to improve the construction efficiency of the“Pre-Piling”jacket foundation of offshore wind turbines and reduce the possibility of safety accidents,the offshore wind turbine foundation positioning and hoisting system is developed,which includes image progress module,3Dmodel display module,video monitoring module and foundation structure monitoring module.Through relevant theoretical calculations and visualizations of real-time data transmitted by sensors on the guidance platforms and jackets(hereinafter collectively referred to as structures),the positioning and monitoring of the whole process of wind turbine foundation hoisting construction can be realized to guide the orderly and rapid construction process.The system has been successfully applied to the Yudean-Yangjiang-Shapa Offshore Wind Power Project.During the hoisting,the inclination angle on the structure platform is always within 3°and is less than 0.2°when it is finally stable,meeting the requirement that the inclination is within 0.5%;there are few outliers in the GNSS positioning data,which does not affect the overall judgment of the position of structures,and the GNSS positioning data eventually tend to the target coordinates.The application results show that with the assistance of the system,the hoisting process of the foundation structures is stable and efficient,and the centimeter-level positioning accuracy of the hoisting of the foundation structures can be achieved.
