Improving the life-cycle costs and efficiency of impressed current cathodic protection systems

This paper evaluates the suitability of 21st century technology for the improvement of performance and efficiency of impressed current cathodic protection systems in Australia, and explores the opportunities that these technologies present.

Current issues such as energy efficiency, servicing costs, local support and obsolescence are analysed to identify the real benefits that may be achieved with these technologies.

The applicable risks of applying the new technology are assessed and a case is made for the fact that these technologies are now well proven and suitable for application in modern CP systems.
