深水平台导管架外加电流阴极保护系统改造
Retrofitting of Impressed Current Cathodic Protection for a Deepwater Jacket
摘 要
南海海域某气田深水平台的导管架下水1 000 d后，在水深较深区域，其电位仍然不能达到阴极保护电位，使导管架存在很大的腐蚀风险。通过对比常见的导管架阴极保护改造方式，并结合南海海域台风较多以及导管架所处水深较深的特点，最终确定该导管架的阴极保护改造方案，即安装远地式辅助阳极外加电流阴极保护（ICCP）系统。并对导管架远地式辅助阳极外加电流阴极保护系统的方案设计及安装过程进行了介绍。结果表明：在远地式辅助阳极外加电流阴极保护系统投入运行后，导管架的电位快速达到了阴极保护电位，且牺牲阳极的消耗速率大大降低。

Abstract
After a deepwater jacket for some gas field in the South China Sea launched for 1 000 days, the potentials of the parts in deepwater area were below cathodic protection potential, making the jacket in corrosion risk. The impressed current cathodic protection (ICCP) system with remote auxiliary anodes was chosen as the final retrofitting method of cathodic protection (CP) by comparing common CP retrofitting methods and combining with the characteristics of typhoons in the South China Sea and the water depth of the jacket. And the design and installation process of ICCP system with remote auxiliary anodes were introduced. The results show that potentials of the jacket reached the protection potential soon and the consumption rate of sacrificial anodes reduced dramatically after the ICCP system with remote auxiliary anodes was installed.
