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.
