基于多波束方法对海上风机基础冲刷状况监测

Monitoring on Scouring Conditions of Offshore Wind Turbine Foundations Based on Multi Beam Method

为了解吸力筒型基础在风机运行过程中的冲刷情况,指导防冲刷作业开展。通过多波束测量方法对广东某风电场3台吸力筒风机基础冲刷状况进行了监测,并将一年内4次多波束测量数据进行对比分析,得出3台吸力筒风机基础详细的冲刷变化情况。结果表明,在风浪流作用下3台筒型基础冲刷情况整体较小,可暂不采取防冲刷措施。提供的监测数据和分析方法旨在为海上风机基础冲刷防护处理和安全性评估提供数据支撑。

To understand the erosion situation of suction tube foundation during fan operation and guide the implementation of anti erosion operations.It monitored the foundation erosion status of three suction tube wind turbines in a wind farm in Guangdong using multi beam measurement method.Four multi beam measurement data within a year were compared and analyzed to obtain detailed erosion changes of the foundations of the three suction tube wind turbines.The results indicate that under the action of wind,waves,and currents,the overall erosion situation of the three cylindrical foundations is relatively small,and anti erosion measures can be temporarily not taken.The monitoring data and analysis methods provided aim to provide data support for the foundation erosion protection treatment and safety assessment of offshore wind turbines.
