摘　　要：为深入了解导管架下水后的阴极保护极化过程,掌握海洋钢结构阴极保护基础数据,设计开发了多通道阴极保护初始极化监测记录系统和相应的数据采集存储程序。该阴极保护初始极化监测系统作为海洋平台导管架阴极保护监测系统的一部分,在陆地施工阶段,将其安装于导管架上部的密封接线箱内,系统由电池供电。导管架下水就位后,在阴极保护监测系统上下模块电缆对接时,可移至室内,由平台供电,实现对导管架阴极保护系统的长期监测,并可通过网络连接实现与计算机终端的通信,以便进行数据显示和分析。系统采样通道多,储存量大,稳定可靠并在现场应用中得到了检验,取得了良好的效果。A multi-channal initial cathodic polarization monitoring system and its data collecting programm were developed for a full understanding of cathodic polarization process of offshore jackets and collecting basic data used for cathodic protection. As a part of cathodic protection monitoring system for an offshore jacket, the ICPMS was installed in a sealed junction box seated at top of the jacket during the period of its construction onland. The monitoring system was powered by battery. After offshore installation of the jacket was completed, the ICPMS can be moved to an indoor terminal computer cabinet and powered by the platform power system, and therefore perform a long term cathodic protection monitoring of the jacket. The ICPMS can communicate with a terminal computer so that the collected data can be displayed and further analyzed. The ICPMS is a multichannel system with a large storage capacity. Its robustness and reliability was proved in filed application.
