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.
How the voyage performed across wave height and Douglas Sea State exposure — recorded waypoint-by-waypoint.
Waypoint-by-waypoint against the historical AIS baseline.
The historical AIS track was pulled from public records and matched against the master’s own reports. The VF Engine then re-routed the same vessel under the weather as it actually occurred — not a forecast. Both tracks were scored by the same FOC prediction model and compared waypoint by waypoint. The 13.31% reduction is the delta sailed at the same speed band, under the same wind and wave conditions.
