Access to weather data isn’t the problem. Forecasts are everywhere. The hard part is turning them into routing decisions you can trust for this vessel, on this voyage, and still defend long after it has ended.

Conditions change after departure
The route that made sense before sailing may not hold three days later. Without someone watching, changes are spotted late and fixed at a cost.

Distance isn’t time
A laden vessel into heavy seas loses speed and burns more fuel to hold schedule. A longer route in better weather often arrives sooner.

Every hour and tonne adds up
Lost time, extra fuel and the emissions that follow feed into CII and MRV reporting — building up voyage by voyage, across the fleet.

Decisions get questioned afterwards
When a charterer challenges speed or consumption, you need proof of the weather and the reasoning behind the route. Rebuilding that after the event is slow, and often incomplete.
Assess
Understand forecast conditions, vessel characteristics and route options before departure, with a bespoke forecast built for each vessel and voyage.
Execute
Daily updated forecasts, routing advisories and a supporting narrative from meteorologists overseeing the voyage 24/7, so vessel and shore teams know what’s ahead and why.
Review
Continuous performance monitoring with automated underperformance alerts, so issues are caught before they become commercial disputes.
Defend
Voyage reconstruction, charter-party benchmarks and structured evidence, using methodologies consistent with English Commercial Court and London arbitration precedent.
