Maintenance Optimization Using Risk-Based Tools

The electricity generation industry has changed significantly throughout the world in the past decade. Demand from shareholders for higher profits and obligation to the statutory requirements has increased. There are also considerable financial risks in market situations associated with the possibilities for major plant failures due to the change in operation mode (e.g., from base load to cyclic operation). This, together with the increasing competition and performance requirements has led to the need for power plants to identify areas of high risk within their business. For successful operation in the current market, the management needs to identify the demands of the market in which the plant operates and be able to operate the plant to meet the market demands. Therefore, increasingly a risk-based management approach is being adopted to deal with the challenging threats and thereby avoiding penalties from the market.

ETD have prepared Guidelines underlining some advanced and smart inspection technologies such as smart corrosion monitoring technique, smart thermal scanning of boiler furnace walls, smart radiographic technique and use of drones and robots for plant inspection. Recent developments of some new NDE (Non-Destructive Examination) techniques for the use of early stage damage detection in P91 and P92 steels were also discussed. An overview of some Monitoring and Diagnostic (M&D) services including the descriptions of their methodologies were also discussed.  The main objective of an M&D was to provide support to the plant operators for the improvement of plant performance by reducing unexpected failures and hence reduce maintenance costs and increase revenues.
