Marine fuel economics
Compare bunkering ports against the fuel economics of the whole voyage
Generate a vessel-level fuel budget that combines sea days, port days, consumption, fuel mix, and source-timestamped VLSFO and MGO prices for Singapore, Rotterdam, and Houston.
The problem
The cheapest quoted tonne is not always the lowest-cost voyage once consumption and fuel mix are included.
Activated outcome
A port-comparison workbook that shows tonnes, blended price, total fuel cost, and difference versus the lowest scenario.
One action, a finished workbook
- 1Load reviewed marine-fuel identifiers for three bunkering hubs.
- 2Set sailing days, hotel load, daily consumption, and VLSFO share.
- 3Compare total voyage fuel cost rather than a standalone bunker quote.
