The paper discusses how performance models can be used for marine gas turbines. A particular performance model, built for on board training purposes is employed to demonstrate the different aspects of this process. The model allows the presentation of basic rules of gas turbine engine behavior and helps understanding different aspects of its operation. A smart designed graphics user interface is used to present engine operation in different ways: operating line, operating points of the components, interrelation between performance variables and parameters etc. The perception of fault signatures on monitoring parameters is clearly demonstrated. Diagnostics capabilities of the existing performance model installed at the Hellenic Naval Academy Gas Turbines Virtual Lab are examined and tested using the measurement data from real marine gas turbines. A case study is discussed in this paper where the model results and the real engine conditions are compared for diagnostic purposes.
