Plant performance and maintenance strategies


The most cost-effective way of prioritizing maintenance

Asset management at plant level needs to introduce effective measures to support commercially viable procedures and techniques to line up plant condition with the mode of operation required by trading. 

Plant asset management concentrates on:

  • plant performance
  • improvement of reliability
  • reduction of operation and maintenance costs
  • relation of operation mode with operation and
    maintenance costs and remaining plant and
    component life.     



Plant performance

For the optimal dispatch of power plants it is important to generate actual performance data of the plant. Plant performance also deteriorates over time. Wear and fouling of plant components can have severe effects on the critical plant performance data.

Ensuring that your trading department has access to accurate plant performance requires knowing your plant’s actual condition and capacity. Your plant manager needs access to periodic unbiased measurements and analysis to optimize the operations and management of your power generation assets. Generation owners worldwide turn to KEMA for independent and accurate measurement and analysis services. And if you want to keep a continuous eye on plant performance, KEMA also provides our performance monitoring tool ThermoWare.


Maintenance strategies

Most power plant components require maintenance to safeguard their functionality according to predetermined performance requirements. Inevitably, a time will come when maintenance is no longer cost-effective and components should be replaced.
Various analyses and improvement methods are currently in use to optimize maintenance activities on power plants, including:
  • failure modes and effects analysis
  • failure modes, effects and criticality analysis
  • reliability-centered maintenance
  • risk-based maintenance and replacement.    

Failure modes and effects analysis
The Failure Modes and Effects Analysis (FMEA) method systematically analyzes all known failure modes of an object and considers the consequences of those failures for the functionality of the object. In essence, FMEA can be considered a reliability analysis of a power plant.
The FMEA results can be used for development of maintenance plans or as input for further analysis. The FMEA methodology deals with the technical aspects of assets without taking the criticality of failures into consideration.
Failure modes, effects and criticality analysis
The Failure Modes, Effects and Criticality Analysis (FMECA) method can augment the FMEA method as it provides a qualitative indication of critical potential failures and adds both the probability and the severity to the equation.
As the FMECA provides a qualitative measure of technical risk to an object, it enables prioritizing maintenance activities. Likewise, maintenance budgets can be best applied to keep components with a high technical risk in good shape. This is the most cost-effective way of prioritizing maintenance.
Reliability-centered maintenance
Reliability-Centered Maintenance (RCM) is a process used to determine the maintenance requirements of any physical asset in its operating context.
To apply RCM, an investigation into the components function as well as operating context must be undertaken, similarly as in the FMEA approach. The results of an RCM analysis are used to optimize the maintenance strategy of a plant.
Risk-based maintenance and replacement
Risk-based Maintenance and Replacement (RBM&R) is a quantitative method for economic optimization of a functional entity in an infrastructure. It comprises both maintenance and replacement to retain the functionality of the object indefinitely.
RBM&R allows calculation of the financial risks, lifecycle costs and economics of alternative maintenance and replacement options. The methodology focuses on the economic aspects of the objects rather than the technical aspects.
