Fuel Performance System FuelMACS®


Based on the SeaMACS IAS platform, FuelMACS® incorporates additional functionality for fuel and energy performance management. It offers a valuable SEEMP tool to ship owners, allowing them to monitor and compare their vessel's or fleet's performance fuel performance in real-time and/or based on historical values. Characterised by high scalability and flexibility, FuelMACS® allows for definition of vessel-specific indicators - one of the crucial points when evaluating vessel performance over time. The system is designed according to the provisions of the MARPOL convention, which requires a Ship Energy Efficiency Management Plan (SEEMP) to be development and Energy Efficiency Operational Indicators (EEOI) to be established for all vessels.

FuelMACS® Features

  • Fuel consumption mgmt.
  • Vessel performance mgmt.
  • Engine performance mgmt.
  • Hull performance

Fuel consumption management is based on fuel flow measurement.

Data for both instant and total fuel consumption is provided - e.g. total per hour, total per voyage.

Emissions and fuel costs are reported per engine, per data, in total and accumulated.

For vessel performance management, vessel speed is included in order to calculate fuel usage in litre per nautical mile (l/nm).

For engine performance management, data for engine power is included in order to calculate fuel consumption in grams per kilowatt hour.

The hull performance management measures shaft torque/power versus speed over time. Once the system is set up for the respective vessel, a reference curve is created. The system is then able to detect speed loss over time by performing analysis of vessel speed versus shaft effect.
