It is known that corrosion has significant impacts on all types of assets with respect to cost, health and safety, environment, community, and stewardship; effective corrosion management reduces losses, extends the service life of assets, and prevents catastrophic failures.

Corrosion Management System (CMS) is a systematic approach to manage corrosion risks through policies, processes, and procedures in an organization; and it should be developed, implemented, maintained, and continuously improved for not only the internal team, but also external suppliers and contractors.

This paper focuses on the lessons learned from the process of implementing a CMS in an operating gold mine. The obstacles and constraints during the process as well as the approaches to overcome them will be discussed. The structured process of dealing with technical corrosion risks will also be illustrated with case studies, including the benefit of corrosion monitoring and data collection for decision making.
