What ocean racing taught us about weather routing
Thirty years of offshore racing meteorology expertise, now applied to AI-driven routing for commercial maritime operations. How Marine Weather Intelligence transfers race-level know-how to every sea-dependent sector.
Maritime route optimisation: how small adjustments can deliver up to 10-15% fuel savings
Weather routing is not just about avoiding storms, it is about finding the optimal balance between speed, sea state, and fuel burn across the full passage. Small course and speed adjustments, made at the right moment, compound into significant savings.
Why slower sailing does not always mean lower fuel consumption
In maritime operations, it is commonly assumed that reducing vessel speed lowers fuel consumption. While true in stable conditions, real-world voyages are shaped by evolving weather and sea state, and the relationship between speed and fuel use is not always what it seems.
Release of MWI Shipping
Marine Weather Intelligence officially presented MWI Shipping at Euromaritime 2026, a dedicated routing and weather forecast platform for the shipping industry, already active on more than 60 vessels.
Hazardous weather zone at sea project

Marine Weather Intelligence honoured at BlueInvest 2025
Marine Weather Intelligence secured the Ocean Intelligence & Autonomous Systems award at BlueInvest 2025 in Brussels, recognising the operational utility of its marine forecasting and routing technology.
Thunderstorm nowcasting: a new layer of safety for offshore operations
Conventional weather forecasts miss localised convective events. Marine Weather Intelligence is developing a satellite-based nowcasting system to provide a 30–90 minute alert window for offshore teams operating in storm-prone regions.
Model qualification: a key pillar of informed routing
Not all weather models perform equally in all regions and conditions. Marine Weather Intelligence is building a rigorous qualification framework to ensure every routing recommendation rests on the most reliable forecast data available.
