The platform
From D-15 to D-Day, smart & informed decisions at every stage.
Not a generic weather tool. A dedicated operational decision layer designed around the specific constraints of offshore energy projects, from early planning to live execution.
Exceedance probability forecasting
Thresholds expressed as exceedance probabilities across wind, wave, and current parameters. Every forecast integrates uncertainty, fully traceable for HSE, insurers, and client records.
Multi-objective operational optimisation
Weather, current, operational limits, and project milestones handled simultaneously, supporting the most complex offshore scopes from foundation installation to cable laying.
HSE-traceable reports & documentation
All weather reports are downloadable, timestamped, and shareable. Every Go/No-Go decision is documented, ready for your HSE files, insurance records, and contractor audits.
Before operations
D-15
- Weather uncertainty integrated into decisions and forecasts
- Advanced weather reports at every project milestone, downloadable
- Operational schedules secured with probabilistic analysis
During operations
D-Day
- Live expert assistance available 24/7 during critical phases

24/7 AI agent monitoring Always on. Always watching.
Always on. Always watching.
Never caught off-guard.
Marine Weather Intelligence continuously monitors every operation, every threshold, every critical window, day and night, so your team can act before conditions become critical.
AI Chat Agent
Intelligent operational assistant
The MWI AI agent delivers weather analyses, go/no-go recommendations, and operability summaries directly in chat, at any hour, without delay.
Real-time alerts
Threshold exceedance alerts
Wind, wave, and current criteria monitored continuously. Push notifications reach your team before hazards breach operational limits.
Window de-risking
Continuous window de-risking
AI-driven monitoring detects weather front exposure and recalculates optimised operational windows in real time, protecting schedules and margins.
Human expert support AI-powered. Expert-backed.
AI-powered. Expert-backed.
Present at every stage.
The AI never sleeps, but when a situation demands human judgement, a dedicated weather expert is available live. Clear guidance, direct support, and 30 years of offshore field experience at your side throughout the critical phase.
Request a demoYour vessels work hard. Your routing should reflect it.
A digital twin built at delivery no longer reflects a vessel after years of offshore rotations. We provide a performance model suited to your offshore units from day one, then refine it with your own data so weather windows and transit recommendations match what each vessel can really do.
Refined with your data, improving continuously.
- Connected to the data you already collect, whatever its form
- Ever closer to your vessel's real behaviour at sea
- Routes that keep getting sharper over time

Real-time weather alerts
Know before the weather becomes a problem.
Marine Weather Intelligence enhances safety management by providing personalised alerts on hazardous conditions, delivered clearly, only when relevant, so your team can act before conditions deteriorate.
Receive alerts by email or directly within the platform. Proximity alerts warn you before dangerous conditions happen.
- 01 Convective zones Proximity-based · 3h ahead
- 02 Thunderstorms Proximity-based · 2h ahead
- 03 Fronts 48h advance warning
- 04 Large swells Height & period threshold
- 05 Strong winds Sustained speed threshold
- 06 Strong gusts Peak gust threshold
- 07 Wind against current Sea state hazard
Operations managers get a consolidated view with Fleet Center: a single dashboard showing every asset's position, weather exposure, and operational status in real time.
Fleet visibility
One view across all your offshore assets.
When multiple vessels and installations are running in parallel, weather risk doesn't affect them equally. Marine Weather Intelligence gives operations and HSE teams a consolidated, real-time picture of every asset's weather exposure, so nothing slips through the gaps.
Global operational awareness Every asset, every weather exposure, every alert, consolidated in one place for your operations and HSE teams.
We know what's at stake
Navigating uncertain weather under operational constraints is complex.
Every unplanned standby day on an offshore project carries a direct operational cost and a compounding effect on schedule, crew safety, and contractor liability.
01 Schedule
Unplanned standby days cascade across the entire project
A single weather standby day triggers day-rate overruns, crew rotations, contractor liability exposure, and downstream schedule compression. Probabilistic planning prevents the chain reaction before it starts.
02 Safety & HSE
Go/No-Go decisions require evidence, not intuition
Marine insurers, charterers, and HSE regulators increasingly require traceable, expert-backed weather decisions. MWI produces fully downloadable, timestamped weather reports ready for your HSE files and insurance records.
03 Forecast accuracy
Single deterministic forecasts hide the risk that matters most
Exceedance probability forecasting replaces binary go/no-go intuition with quantified risk assessment. When the probability of exceeding your wind threshold is 30% vs 5%, that difference changes every operational decision.
04 Cost & efficiency
Weather downtime is the largest controllable cost in offshore projects
Weather-optimised operational windows, real-time performance optimisation, and live expert support directly reduce standby days and fuel consumption across the project lifecycle.
Why Marine Weather Intelligence
What offshore ocean racing taught us about weather routing.
Offshore ocean racing is an extreme laboratory for weather decision-making, where margins are small, consequences of error are immediate, and every forecast must be acted on under pressure. For more than 30 years, our founders have operated in this environment. That expertise is now embedded in every recommendation we make for offshore energy operations.
Christian Dumard's experience spans the Vendée Globe, Volvo Ocean Race, and Route du Rhum, as well as complex maritime operations including oil platform towing and the transport of the James Webb Telescope. AI does not replace this expertise. It scales and operationalises it.

Client testimonials
Trusted in the most demanding offshore operations.
You would not believe, but we managed to discharge an hr. ago. In March, when trend become moving towards monsoon season and in open waters. Very big thanks for your team valuable and active support. We are happy here, cargo owners also happy, no need to wait end of monsoon season.
Capt. Jørgen Føyen Seaway7 Senior Operator, Heavy Transportation
Tailor-made weather forecasts and routings from MWI are definitely a great decision tool to control the risks and cost on our dry/wet tow.
