Built for modern voyages
Volatile fuel prices, shifting weather, and tightening regulations make static voyage plans quickly outdated leading to missed savings and increased operational risk. Voyage Optimisation continuously adapts every decision to reduce fuel spend, improve performance, and protect margins.
Real-Time Weather Optimisation
Re-route as the forecast shifts before margin slips
Receive updated forecasts every 48-72 hours and automatic recalculations when conditions shift. Evaluate route adjustments based on weather exposure, cost impact, and emissions performance before making operational changes.
Charter Party Adherence
Plan voyages that respect every CP clause
Build voyage plans that stay within Charter Party speed bands, consumption clauses and weather routing windows from the outset. Voyage Optimisation factors CP terms into routing calculations so the recommended plan is commercially defensible before the voyage begins, not contested after it ends.
AI-powered Fuel Models
Vessel-specific fuel prediction with measurable accuracy
93% accurate vessel-specific fuel predictions. Fuel models combine naval architecture, machine learning and historical vessel data to deliver DNV-verified accuracy enabling precise cost forecasting, sharper voyage planning and reduced performance deviation on every route.
How Voyage Optimisation works?
Voyage Optimisation runs every routing decision through live weather, market and emissions intelligence — so the recommended plan protects margin and CII at the same moment.
Routing simulation at scale
Every voyage scored on bunker cost, time and emissions exposure before the order goes out. Backed by the ZeroNorth platform's transaction-backed methodology.
Live weather integration
Forecasts refresh every 48–72 hours. Routes recalculate automatically when weather windows shift, so the plan stays current rather than stale.
Charter Party-aware planning
Voyage plans factor in CP speed bands, consumption clauses and weather routing windows. The recommended route is commercially defensible from the outset.
Connected across the platform
Routing decisions flow into SmartShip for execution monitoring, into Bunker Procurement for stem planning, and into Emission Analytics for compliance evidence. No re-keying.
Strong differentiator
The ZeroNorth advantage
Intelligence built for real maritime operations at scale
AI fuel models grounded in vessel physics
Fuel predictions combine naval architecture, machine learning and historical performance delivering DNV-verified accuracy. CII and EU ETS impact on every routing decision comes from ZeroNorth Emission Analytics, so the number you trade on is the number you report.
Continuous optimisation, not static planning
Routes and speed recommendations update automatically as weather and operational conditions change, ensuring decisions remain aligned with real-world dynamics.
Fleet-level visibility and control
Optimise individual voyages while maintaining oversight across the entire fleet enabling coordinated performance management, not isolated decision-making.

What is voyage optimisation in shipping?
Voyage optimisation is the process of determining the most efficient route and speed for a vessel by analysing weather conditions, ocean currents, vessel performance, fuel consumption, and operational constraints. The goal is to minimise fuel costs, reduce emissions, maintain schedule reliability, and ensure safe navigation.
How often are weather forecasts updated?
Weather forecasts are updated every six hours, and the system automatically recalculates optimisation scenarios when conditions change. This ensures routing and speed recommendations reflect the most current data available.
Can voyage optimisation integrate with existing fleet systems?
Yes. Voyage Optimisation can integrate with existing fleet management, voyage planning, and performance monitoring systems. This allows operators to incorporate optimisation insights directly into their operational workflows without disrupting existing processes.
How does ZeroNorth’s Voyage Optimisation work?
ZeroNorth’s Voyage Optimisation combines real-time weather forecasts, vessel-specific fuel models, and operational safety parameters to generate optimal routing and speed recommendations. The system continuously recalculates routes as conditions change, allowing operators and onboard teams to make informed decisions throughout the voyage.
How much fuel or emissions can voyage optimisation reduce?
Fuel savings depend on vessel type, route, and weather conditions, but optimised routing and speed adjustments can typically reduce fuel consumption by 3–10% per voyage. These reductions directly translate into lower operating costs and measurable emissions savings.
How does voyage optimisation improve commercial performance?
Voyage optimisation continuously adjusts route and speed based on weather, vessel performance, and arrival constraints. This helps reduce fuel consumption, protect Charter Party compliance, and improve Time Charter Equivalent (TCE) across voyages.
