Knowledge Based Assessment of the Condition of Gas Turbines
The Need
� Gas turbines are the critical drivers of the plant.
� Do not want to stop.
� Need maximum operating efficiency.
� Need to know what to maintain and when.
� Impossible to manually assess the turbine condition.
The Desire
� Understand the condition of the turbine.
� Detect problems at the earliest possible stage.
� Understand what happens when problems arise.
