Beijing Branch, CNOOC Energy Technology Service Limited, Beijing 100027, China) Abstract: 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 r
