Zusammenfassung:	The invention refers to a method and a calculation unit (10) for calculating a load skewness result (LSR) for a determination of service intervals for a turbine (GT). The method comprises:- Receiving (S1) a continuously measured load signal (1) over time, indicating a load of the turbine (GT) during operation thereof;- Determining (S4) a load percentage signal (lp) over time as a deviation of the received measured load signal (1) from a maximum capacity signal (mc), wherein the maximum capacity signal (mc) represents a maximal possible load to be generated at a given time and is calculated from continuously measured sensor signals (s), representing operating parameters of turbine operation;- Calculating (S5) a load percentage distribution (LPD) based on the determined load percentage signal (lp);- Calculating (S6) a load skewness factor (LSF) as a measure of an asymmetry of the calculated load percentage distribution (LPD);- Providing (S7) the load skewness result (LSR), comprising the calculated load percentage distribution (LPD) and the calculated load skewness factor (LSF).
