摘　　要：牺牲阳极阴极保护技术是防止海洋平台腐蚀的一种可靠手段。该文以导管架平台为研究对象,选取DNV设计准则,确定牺牲阳极的数量及相关布置,设计一套可靠的牺牲阳极阴极保护系统方案。借助数值仿真技术,通过研究导管架表面电位分布及腐蚀速率的变化来探究服役期间导管架平台阴极保护效果随阳极溶解的变化。Sacrificial anode cathodic protection technology is a reliable means to prevent corrosion of offshore platforms.In this paper,taking the jacket platform as the research object,selecting DNV design criteria,determining the number and related layout of sacrificial anodes,and designing a reliable sacrificial anode cathodic protection system scheme.With the help of numerical simulation technology,the change of cathodic protection effect of the jacket platform with anodic dissolution during service was explored by studying the changes in potential distribution on the jacket surface and corrosion rate.
