Corrosion Mitigation of Ageing Buried Steel Pipelines in Metropolitan Sydney

Paper No. 95
J Galanos, Corrosion Control Engineering, Sydney, Australia.


A number of buried steel pipelines have been installed in Sydney to transport petroleum, gas, water and other products. While most of these pipelines have lasted well, due to robust maintenance, this paper discusses the challenges associated with many aspects of pipeline maintenance, including upgrading cathodic protection (CP) systems, CP test points, dig-ups and ILI (intelligent pigging). This paper also discusses the challenges associated with third party works and impacts to the pipeline, both now and in the future.
