摘要
针对海上风电平台水下导管架及支撑钢管桩基础的防腐保护,提出一种新的阴极保护方案,该方案引入远地式牺牲阳极地床,具有安装方便,施工安全性能高、时间短、费用低、回收更换方便等优点。另外,针对该方案预先采取CPMaster模拟软件进行分析,通过有限元分析和数值模拟来评价其阴极保护效果,同时与三峡某海上风电平台基础的实测数据进行对比。结果表明,模拟结果与实际测量数据基本一致,水下导管架及支撑钢管桩保护效果完全满足要求,确定了该种保护方案的有效性,可为海上风电平台基础的阴极保护设计提供指导。
A remote sacrificial anode bed is proposed for the anti-corrosion protection of the underwater jacket and the supporting steel pipe pile foundation of the offshore wind power platform.The scheme is introduced into the far away sacrificial anode ground bed,which has the advantages of convenient installation,high construction safety performance,short time,low cost,convenient recovery and replacement,etc.In addition,CP master simulation software is used for analysis in this scheme,and the cathodic protection effect is evaluated by finite element analysis and numerical simulation.At the same time,it is compared with the actual measured data of an offshore wind power platform in the Three Gorges.The results show that the simulation results are basically consistent with the actual measurement data.The protection effect of the underwater jacket and supporting steel pipe pile fully meets the requirements.The effectiveness of this protection scheme is determined,which can provide guidance for the design of cathodic protection for offshore wind power platforms.
