Corrosion is one of the most common threats for pipelines and operators all around the world spend huge budgets on mitigating the risks of corrosion.
The aim of corrosion management systems is to ensure that the pipelines and other relevant assets are safe and protected for the long-term operations and are harmless to the environment. A properly implemented corrosion management system can increase return on investment while decreasing life cycle costs.
Application of an effective corrosion management program is an important element for security and reliability of the operations of refineries or any oil and gas production facilities. The implementation of the system starts from the initial stages of conceptual design and is carried out throughout the entire process until the end of the life of the facilities.
How is it done?
At the first stage of planning, a comprehensive list of potential corrosion risks is compiled. Each risk factor is evaluated according to the industry standards, previous experience as well as the process conditions. Having experienced experts for an effective and optimal risk assessment and planning of mitigation measures is of high importance as when working on a new facility, not enough existing prior data is available to base the corrosion management planning upon. Therefor it is mostly the operation team’s past experience and experimental data that can be used for corrosion assessments.
The second stage of developing a corrosion management system is identifying the relevant controls to be used which shall be in accordance to industry standards and guidelines.
The third step in planning the corrosion management strategy is selection of monitoring and inspection techniques to determine the effectiveness of the deployed barriers. The right combination of monitoring and inspection techniques is necessary as monitoring helps in preventing the corrosion while inspection can identify the damages that already have taken place.
