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.

24/7 AI agent monitoring
Exceedance probability forecasting
Multi-objective operational optimisation
HSE-traceable reports & documentation

Continuous automated monitoring tracks vessel positions, watches for evolving weather risks, and alerts your team before conditions deteriorate — around the clock, without gaps.

Thresholds expressed as exceedance probabilities across wind, wave, and current parameters. Every forecast integrates uncertainty — fully traceable for HSE, insurers, and client records.

Weather, current, operational limits, and project milestones handled simultaneously, supporting the most complex offshore scopes from foundation installation to cable laying.

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.

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.

MWI's probabilistic approach changed how we make Go/No-Go decisions. Having exceedance probability data for each threshold, not just a forecast, gave us the confidence to act and the documentation to back it up with our insurers.
For foundation installation campaigns, every weather standby day is a significant cost. MWI's D-15 forecasting and probabilistic window analysis helped us plan tighter, execute safer, and reduce our weather exposure materially.
The combination of AI model selection and human expert support is exactly what our operations need. The alerts are relevant, the reports are HSE-ready, and the team is available when it matters most, during critical phases at sea.
