Claim 11:
12. A processor comprising a calculation unit for calculating a load skewness result for a determination of service intervals for a turbine, based on historical and continuously measured sensor data of turbine operation, comprising:
a plurality of sensors operatively coupled to the turbine;
a load interface coupled to a respective sensor of the plurality of sensors to receive a continuously measured load signal over time, the load signal indicative of a load of the turbine during operation of the turbine;
a sensor interface coupled to further respective sensors of the plurality of sensors to receive continuously measured sensor signals, the continuously measured sensor signals representing operating parameters of the turbine;
the processor having a first processor unit configured to determine a maximum capacity signal, wherein the maximum capacity signal is calculated based on the received sensor signals and indicates a maximal possible load to be generated at that time;
the processor having a second processor unit configured to determine a load percentage signal over time as a deviation of the received load signal from the maximum capacity signal;
the processor having a third processor unit configured to determine a load percentage distribution based on the determined load percentage signal and which is further configured to calculate a load skewness factor as a measure of an asymmetry of the calculated load percentage distribution;
the processor configured to generate a graphical representation indicative of the load skewness result; and
a graphical user interface responsive to the graphical representation to simultaneously display the calculated load percentage distribution over time and the calculated load skewness factor over timer.
