Repair and Prolonging Life Technology of Impressed Current Cathodic Protection for Offshore Oil Platform

The repair and prolonging life technology of cathodic protection for offshore oil platforms is introduced,and the necessity of impressed current cathodic protection(ICCP) technology instead of sacrificial anode technology to repair and prolonging life for platforms is expounded.A repair and prolonging life technology of ICCP for offshore oil platforms was built by studying the materials,equipment and design of ICCP system.This technology is applicable to repair and prolonging life of cathodic protection for offshore oil platforms in relatively deeps sea.
