摘要:

通过对南海A 平台导管架阴极保护监测结果的分析, 研究了该平台下水一年后导管架的阴极保护状态。结果表明, 该平台下水后, 导管架各节点电位及牺牲阳极电位均达到保护, 阴极保护状态良好。阴极保护监测系统运行稳定, 双电极探头未发现损坏, 所得监测结果翔实可靠, 对该海域新建平台导管架监测系统有着重要的借鉴价值。

Analysis of cathodic protection monitoring system on offshore Jacket in South China Sea

Abstract:

The data obtained from the cathodic protection monitoring system on the jacket platform in South China Sea was analyzed and discussed in this paper. The potentials of the joints and the sacrificial anodes have reached the protective potential one year after launching into water. The corrosion sensors are in good conditions and the monitoring results have an important value on the design and construction of offshore structures.

Key words: deepwater corrosion corrosion monitoring offshore jacket cathodic protection
