Abstract
The foundation and impressed current cathodic protection (ICCP) system of large-scale storage tanks was summarized.The optimal ICCP system for large-scale storage tanks is introduced.The measurement and system commissioning methods for large-scale tank’s ICCP system are also discussed after studying the National Standards,NACE and API standards.Some new ideas are presented based on the practice.
