Availability Improvement Methodology in Thermal Power Plant

Henry Pariaman, Iwa Garniwa, Isti Surjandari, Bambang Sugiarto


Availability of a complex system of thermal power plant is strongly influenced by maintenance program and component reliability. Various maintenance techniques, likes RCM (reliability-centred maintenance), RBM (risk based maintenance) and CBM (condition-based maintenance), have been applied to improve the availability. Implementation of RCM, RBM, CBM alone or combined RCM and RBM or RCM and CBM is a maintenance technique used in thermal power plants. This study develops an new maintenance methodology integrating RCM, RBM and CBM to increase the availability of thermal plants. The method generates MPI (Priority Maintenance Index) and FDT (Failure Defense Task). MPI is used to determine the priority of components in maintenance program. FDT consists of the tasks of monitoring and assessment of conditions other than maintenance tasks. Both MPI and FDT obtained from development of functional tree, failure mode effects analysis, fault-tree analysis, and risk analysis (risk assessment and risk evaluation) were then used to develop and implement a plan and schedule maintenance, monitoring and assessment of the condition and ultimately perform availability analysis. The results of this study indicate that the reliability, risks and conditions-based maintenance methods, in an integrated manner can increase the availability of thermal power plant.
