ABSTRACT
The reinforced concrete infrastructure managed by the States of Jersey suffers from steel reinforcement corrosion initiated by chloride ions from the marine environment. The Impressed Current Cathodic Protection (ICCP) system has performed well with significant negative shifts in the steel as expected, indicative of adequate corrosion protection. A few anodes have needed to be replaced but there have been no whole system failures and there is every indication with the low voltage and currents required to achieve corrosion protection to the steel that these anodes will continue to operate for many years with minimal maintenance. The initial investment in ICCP systems, targeted at specific corrosion problem areas has reduced the long term costs of managing these structures and has extended the effective service life and residual value. In 2011 the computer controlled power and control system was replaced, as it had become obsolete and the ICCP system was reconfigured from 15 zones to 8 zones to simplify operation.
