A CMS (Corrosion Management System) is the management system including specific documentation identifying the processes and reengineering procedures affecting the corrosion management which is basically needed for Planning (PLAN), Implementation (DO), monitoring and measurement (CHECK) and defining the corrective action (ACT), also the ability of the organization to manage the threat of harmful corrosion phenomenon for future asset integrity management.

Choosing an appropriate CMS model which is fitted for gas supply chain from basic design and early engineering via installation, commissioning, operation and sweetening process, transmission, and distribution of the natural gas is the main managerial challenge for the stakeholders of this project. (Note that there is no events or standard model for implementation of CMS in such this case)

The purpose of this paper is introducing a methodology for selecting a suitable CMS roadmap.
