There is increasing pressure on infrastructure owners and manager to ensure their asset base is safe and reliable, and maintains acceptable levels of service for the duration of the expected life of the asset.  This requires balance with often limited budgets, requiring optimized approaches to be developed and implemented.  This balance becomes critical when a requirement to extend the life of an asset must be actioned.

With the release of ISO 55000 ‘Asset management — Overview, principles and terminology’ (2014), and other supporting guidelines, there is improved guidance on the strategic whole-of-life management of an asset base, and there are a number of techniques that can be adopted to achieve this goal.  When an asset is affected by corrosion, this can threaten its longevity and serviceability, with consequences for the functionality of the individual asset and the larger network which it supports.

This paper provides practical examples where such issues were identified and discusses the various asset management and corrosion-control /management strategies that were developed and implemented to mitigate the corrosion risks.  Examples have been provided from various asset infrastructure classes, such as water, ports, and transportation.  The requirements for developing and applying appropriate asset management strategies based on individual or network-based priorities are also discussed.
