The brief

Counterfactual route analysis — what would have happened under optimal routing. The evidence you need when large demurrage claims land on your desk.

Under a time charter, you pay for fuel. VesselFront gives charterers counterfactual route analysis: what would have happened under optimal routing. This is the evidence you need when large demurrage claims land on your desk.

Oil majors and trading houses, spot charterers, time charterers running tonnage, and industrial charterers care about different things. But they all bet on speed, consumption, and arrival windows — and every one of those bets is decided by conditions you don’t control but increasingly can anticipate.

The features charterers actually use on a Wednesday at 14:00.

Hindcast on real weather

What the voyage should have consumed under the weather that actually occurred. Numbers, not opinions.

Speed-performance claims

Verify or challenge speed claims against the model’s predicted FOC curve for the vessel.

Plain-English narrative

Every reconstruction comes with an LLM-generated explanation suitable for arbitration filings.

India-to-Brazil voyage from Sikka to Niterói, routing south through the Indian Ocean, around the Cape of Good Hope, and across the South Atlantic – 30 days, 7,922 nm. The operational risk on this lane is the Cape rounding, where the route hit its southernmost point at 35.9°S in the Roaring Forties. The optimised track cut Sea State 6+ exposure (≥4.0 m) nearly in half – from 6.4% of the historical track to 3.6% – and reduced Sea State 5+ exposure from 36.0% to 26.0%. Route-averaged significant wave height was 2.17 m. The vessel operated on VLSFO throughout with no ECA transits, so the 13.31% FOC reduction (89 MT saved) is a pure routing-and-speed optimisation result, not a fuel-grade effect.

Norway-to-UK tanker shuttle from Sture to Tetney Terminal – 35 hours, 438 nm, southwest across the central North Sea, May 2019. The entire crossing sits inside the North Sea SECA, so the 6.0 MT saving was realised entirely on ECA-grade fuel. Conditions were uniformly rough – the historical track ran at 100% Sea State 4+ across the full crossing, so the optimiser couldn't route around weather, and the 2.95% distance and 2.97% duration reduction came from finding a more efficient corridor through it rather than from sea-state avoidance. Mean SOG 12.37 kn.

16-day Brazil-to-US-Gulf transit on a tanker, October–November 2018. A benign-weather voyage: both the optimised track and the historical replay stayed entirely within Sea State 3–4 (peak significant wave height 2.21 m optimised, 2.16 m historical, mean 1.40 m). With no weather window to route around, the gains compress – the optimised track was 46 nm shorter, 3 hours faster, and burned 1.67% less fuel (350.48 vs 356.44 MT). A reference case for what routing optimisation delivers on a calm-conditions voyage.
