## Fuel consumption profile

The ship fuel consumption profile represents the balance of fuel used by different combustion systems (e.g. main engines, auxiliary engines and boilers). It can give an indication if any of the ship systems consume relatively higher fuel compared to expected best-practice levels. This then could be a good lead for further investigations of the causes of excessive fuel consumption and thereby identification of energy efficiency measures.

Figure below shows an example of a ship’s fuel consumption profile; indicating percentages of fuel used by various systems. Comparing these with industry benchmarks and other ships in the fleet will indicate if any of the system may have been used inefficiently (MariEMS 2017).
