10 signals, one score

Every voyage risk score fuses ten independent intelligence signals through weighted, active-signal scoring. Zero-count signals are excluded automatically—only real threats drive the composite.

VoyageRiskScore

Quantified port-to-port risk assessment fusing ten independent intelligence sources into a single 0–100 score. Full driver breakdown shows exactly what's driving the risk.

  • 10 weighted signal sources with active-signal redistribution
  • CII safety floors prevent under-scoring war zones
  • Data confidence indicator with missing source warnings
  • Sub-2s scoring across 510+ port pairs

Stochastic Monte Carlo

500 weather-coupled simulations per voyage. AR(1) correlated weather sequences produce realistic ETA distributions, not just point estimates.

  • Beaufort speed curves per vessel type & load condition
  • Per-segment weather from Open-Meteo marine API
  • P10–P90 ETA distribution with median highlight
  • Container, bulk, tanker, LNG, general cargo models

Fleet & Dark Activity

Real-time vessel tracking with automatic dark activity detection. AIS gaps, speed anomalies, and unauthorized zone entries trigger instant alerts.

  • AIS gap detection with configurable thresholds
  • Dead reckoning position estimation during gaps
  • Geofence zones with entry/exit monitoring
  • Fleet-wide risk dashboard with KPI metrics
