Bunker Consumption
Fuel efficiency and cost modeling for vessels.
Bunker: The Core Cost of Shipping
Bunker fuel represents the single largest variable cost in maritime transport, often accounting for 50-60% of a vessel's total operating expenditure. Accurate estimation is vital for voyage planning, bunkering (refueling) logistics, and compliance with modern environmental standards like CII (Carbon Intensity Indicator) and EEXI.
The Engineering Formula:
Daily ME Cons = (Power × Load Factor × SFOC × 24) / 1,000,000
This tool utilizes SFOC (Specific Fuel Oil Consumption) metrics�measured in grams per kilowatt-hour�to determine mass-based consumption. Carbon emissions are calculated using the IMO standard emission factor of 3.114 for HFO (Heavy Fuel Oil), providing technical managers with a foundational baseline for voyage carbon accounting.
