导管架牺牲阳极阴极保护数值模拟评价与优化改造
Numerical Simulation Evaluation and Optimal Retrofit of Sacrificial Anode Cathodic Protection Systems for Offshore Jackets
摘 要
对某海洋平台的调研发现, 水下机器人(ROV)水下电位检测只能够反映检测区域的阴极保护有效性, 而采用悬臂法电位检测的结果表明,ROV未能检测的浅水和导管架内部区域阴极保护已失效。为此, 借助于数值模拟的方法全面评估了两个海洋平台水下结构牺牲阳极阴极保护系统的有效性, 与现场检测结果进行了对比。同时, 针对欠保护区域采用数值模拟方法进行了优化改造。

Abstract
High corrosion risk exists because the CP effectiveness is unknown. Protected potentials detected by ROV (remote operated vehicle) and other techniques in limited locations in a case showed that such results could not reflect the CP condition of the entire underwater structures. Numerical simulation technique was used in CP assessment for two platforms, and the results showed a good coherence with potential detection data. Meanwhile, the simulation technique was used to optimally design retrofits for the under-protection area in a platform.
