Risk-Based Maintenance (RBM) technique has been generated for a 600MW fossil-fired power boiler plant accumulated operating times exceeding 100,000h. The RBM is defined as a multiplication the likelihood of a component failure occurring by the consequence of that failure within semi-quantitative method. That is based on engineering judgment, supported by necessary life assessment. The assessment provides for both the safety and financial risk of failure of each pressure part of the boiler. As a result, the present study shows that the inspection period can be extended from 24 months to 48 months. The RBM technique is an advanced technique to improve maintenance plan of a plant that is considered inspection priority, safety, and cost reduction based on many industrial experiences.
