A vessel optimization application offering combined tidal and nontidal (ocean) current data has been launched for integrated vessel speed and route optimization. Developed by Tidetech, the application offers resolution of six nautical miles at 60-minute intervals in a six-day forecast. Significant passage time savings have been demonstrated in simulations.
Tidal currents are fast moving, dynamic and dominant inside the continental shelf – in water depths of 200m or less – and are inherently predictable years ahead. Non-tidal currents are slow moving and dominant in the deep ocean, driven by entirely different processes that cannot be accurately forecast beyond five to six days. Tidetech also offers additional high-resolution tidal current models for highly trafficked, tide dominant regions with resolutions ranging from 200m to two nautical miles, and multiple global ocean models.
