Engineered for Sea Routing & Ship Safety

Weather data is not just visualized on a chart — it is mathematically ingested into hydrodynamic ship models to predict added resistance, voyage delay, and heavy-weather navigation hazards.

Beaufort Speed Loss & Fuel Impact

Along-route weather interpolation evaluates wind resistance and Townsin-Kwon added wave resistance, calculating ship speed penalties and bunker consumption adjustments.

Cross-Sea & Rogue Wave Probability

Spectral decomposition computes the encounter angle between swell and local wind waves. Flags dangerous perpendicular cross-seas and Benjamin-Feir Instability (BFI) rogue wave zones.

IMO MSC.1/Circ.1228 Stability

Evaluates dynamic ship stability criteria for heavy weather navigation: parametric rolling, synchronous resonance, surfing, and broaching-to hazards based on ship length and speed.

Port Conditions & Berth Operability

Combined port weather API: delivers 10m wind, maximum gusts, significant wave height, and 48-hour astronomical tide curves in a single call for drydock flooding and crane ops.

Ocean Currents & Tidal Streams

Combines deep-sea geostrophic current vectors with coastal tidal streams to compute real speed-over-ground (SOG) gains in Straits of Malacca, Dover, Singapore, and Messina.

Polar Code Sea Ice Navigation

Incorporates sea ice concentration contours and sub-zero freezing spray thresholds to guide safe Northern Sea Route and Northwest Passage routing outside ice limits.
