Current Data Analysis
Marathon has provided operating data of 1 year for the Platformer heater from 2 nd
November 2017 to 1 st November 2018. FIS carried out a detailed analysis of the
data and the data is plotted with respect to time to observe the operating trend
and variation with respect to the design value.
