Fuel oil consumption analysis

It is crucial for shipping companies to make strategic decisions to optimize and reduce their fuel oil consumption (FO) in order to minimize cost as well as to decrease their CO2 emissions and be compliant with international regulations. An a priori estimation of vessels’ fuel oil consumption for a forthcoming voyage has not been an easy task yet. Fuel oil consumption is accounting for almost 50% of the total voyage cost.

METIS, utilizing advanced analytics is able to provide great help on F.O. management with functionality such as the following:
  • Quantifies the amount of fuel used, and therefore gives a reliable cost calculation 
  • Leads to effective and efficient agreements between the charterer and the maritime company
  • Supports the cost estimation of a future voyage
  • Optimizes the fuel effective route planning of a future  voyage
  • Helps the budget planning of a maritime company
  • Indicates possible vessel faulting/fouling

Detailed F.O. Consumption Analysis for M/E & DGs

The F.O. analysis provided by METIS is based on the real-time  collection and processing of the following data: 
  • The output of the flowmeters, e.g. the FO consumption of the various consumers (Main Engine, Diesel Generators, Boilers, etc.)
  • Cargo profile parameters
  • Hull and propeller operation parameters 
  • The vessel speed with respect to the ground
  • Sea/Weather conditions

As long as particulars regarding the vessel, the rudder, the propeller, are known, the following quantities can be calculated:

  • The actual fuel total consumption per consumer and the actual fuel consumption rate of the vessel
  • The normalized fuel consumption rate of the vessel with respect to the fuel that is used
  • Information about the correlation between fuel consumption and the vessel speed
  • Information about the correlation between fuel consumption and the power delivered to the propeller 
  • The comparison with reference lines such as the charterer’s agreement or the sea trials
