Maintenance Improvement on Feed Water System of Steam Power Plant: A Lesson Learned of the Application of Reliability-Centered Maintenance 3

Abstract The feed water system is one of the most important components of steam power plants because it defines the system’s performance. Quick turnaround time is an important factor in operations that should be achieved to avoid causing interruptions. Maintenance techniques should, therefore, be effectively used to prevent the failure modes that lead to system failure. Specifically, this research aims to implement the Reliability-Centered Maintenance (RCM) 3 on the feed water system to improve its maintenance. The study assesses the important failure modes from failure history and develops new maintenance tasks to address these issues. The following have been integrated upon the application of RCM-3: 15 activities are planned by condition, eight are restored, and two are discarded. These improvements minimize the probability of system failures and, at the same time, improve the reliability factor. This research offers useful knowledge and efficient ways to enhance the maintenance approaches in steam power plants, thus ensuring more reliable operations.
