An approach to achieving the ambitious goal of cost effectively extending the safe operation life of energypipeline to 100 years is the application of health monitoring and life prediction tools that are able to provideboth long-term remnant pipeline life prediction and in-situ pipeline condition monitoring. A critical stepis the enhancement of technological capabilities that are required for understanding and quantifying theeffects of key factors influencing buried steel pipeline corrosion and environmentally assisted materialsdegradation, and the development of condition monitoring technologies that are able to provide in-situ monitoringand site-specific warning of pipeline damage. This paper provides an overview of our current research aimedat developing new sensors and electrochemical cells for monitoring, categorising and quantifying the leveland nature of external pipeline and coating damages under the combined effects of various inter-relatedvariables and processes such as localised corrosion, coating cracking and disbondment, cathodic shielding,transit loss of cathodic protection.
