Every meteorological and oceanographic variable in the TrustedDocks infrastructure originates from accredited global agencies, research centers, and verified satellites. Fully unified and accessible through api.trusteddocks.com.
The premier deterministic atmospheric numerical weather prediction model produced by the US National Centers for Environmental Prediction (NCEP). Provides 3-hourly stepped fields out to 120+ hours.
Multi-grid WAVEWATCH III spectral ocean wave model providing full partitioning of wind-sea and swell energy. Decouples complex multi-directional sea states across open ocean basins.
European Centre for Medium-Range Weather Forecasts open data pipeline. Extends voyage planning visibility beyond standard 5-day windows up to 240 hours for deep-sea passages.
Copernicus Marine Environment Monitoring Service global physical ocean analysis. Resolves oceanic circulation, Gulf Stream / Kuroshio drift velocity, and Arctic sea ice concentration.
Hydrodynamic tidal atlas assimilating 34 tidal constituents (M2, S2, N2, K1, O1, etc.) combined with local port tide gauges for exact water level and tidal stream calculations.
Long-term satellite and reanalysis baselines from NASA POWER (MERRA-2) and ECMWF ERA5. Identifies seasonal tropical cyclone tracks, gale probabilities, and port operability downtime.
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.
Along-route weather interpolation evaluates wind resistance and Townsin-Kwon added wave resistance, calculating ship speed penalties and bunker consumption adjustments.
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.
Evaluates dynamic ship stability criteria for heavy weather navigation: parametric rolling, synchronous resonance, surfing, and broaching-to hazards based on ship length and speed.
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.
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.
Incorporates sea ice concentration contours and sub-zero freezing spray thresholds to guide safe Northern Sea Route and Northwest Passage routing outside ice limits.
Our metocean datasets seamlessly feed routes.trusteddocks.com. Whether simulating Rotterdam to Singapore via Suez or Cape of Good Hope, the system computes wind resistance, wave encounters, and real-time voyage optimizations based on accurate ship polar performance curves.
