MWI Towage & Heavy Transport

When the cargo can't wait, you need better planning.

The most reliable weather and routing intelligence platform for towage, heavy lift, and abnormal marine transports. Navigate weather uncertainty with confidence, even under operational constraints.

24/7 Expert monitoring
D-15 Weather window planning
100% Traceable decisions
We know what's at stake

Weather is the most uncontrolled variable in complex marine transport.

And the most consequential. Every missed window and every suboptimal decision carries a direct operational and financial cost.

01 Weather window

A missed departure window can cost more than the entire routing service

Towage and heavy lift operations depend on precise weather windows. A delayed departure triggers day-rate overruns, port congestion, and cascading schedule impacts.

02 Safety

Complex tows have zero margin for error under adverse conditions

A tow in heavy seas, a counter-current event, or an unexpected frontal passage can place crew, cargo, and third parties at serious risk.

03 Compliance

Insurers and port authorities require documented Go/No-Go decisions

Marine insurers, charterers, and flag authorities increasingly require traceable, expert-backed weather decisions. A verbal briefing is no longer sufficient.

04 Cost & efficiency

Suboptimal routes inflate fuel and day-rate costs by 15–25%

Routing around adverse weather without data costs more than routing through it safely with data. Tow resistance modelling reduces operational cost without compromising safety.

Adaptive vessel performance
Multi-objective routing
Probabilistic Go/No-Go decisions
Live assistance 24/7

Tow resistance, sea state effects, and vessel-specific speed curves factored into every routing calculation throughout the voyage.

Weather, current, operational limits, port windows, and cargo motion criteria handled simultaneously, not as a sequence of trade-offs.

Thresholds expressed as exceedance probabilities. Every forecast integrates uncertainty, full traceability for insurance, port authorities, and client records.

Direct access to a dedicated routing expert at any hour, ensuring continuity and accountability throughout the critical phase.

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 operations proceed with complete confidence.

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 24h 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
Marine Weather Intelligence Fleet Center, live vessel positions, routing status, and weather overlay across multiple active towage and heavy transport operations

Operations teams get a live view of every tow in progress with Fleet Center: a consolidated map showing position, routing status, and weather exposure across all active operations.

Fleet visibility

View your fleet immediately and improve operation planning.

A centralised overview of every vessel under your responsibility, position, heading, routing status, and last update, all on a single live map with full weather data overlay.

Global operational awareness Every tow, every weather exposure, every alert, consolidated in one place for your operations teams.
