SpaceNav combines information obtained from various (spaceborne, seaborne and coastal) sensor systems and weather forecast data into advanced numerical models to calculate the optimum sail plan for any vessel — continuously and in real-time. Optimized sail plans are communicated to the ships for multiple benefits (depending on the chosen optimization criteria), for instance to save fuel, reduce pollution, limit structural fatigue or to improve passenger and crew comfort.
SpaceNav fuses ship-specific parameters such as yaw, pitch, roll, sailing speed, GPS position, structural stress, engine parameters, drift, loading condition, wetness, etc. with real-time weather and sea state observations. Observations are acquired through several Earth observation platforms and include information about waves, winds, currents, sea ice concentration and drift. By combining observations from multiple sensors, weaknesses of one particular sensor are compensated for by the characteristics of another. The sensor suite is chosen such that the sensors' capabilities partly overlap and complement each other. This makes SpaceNav an all-weather, 24/7 surveillance and sail plan system.
All these observations, parameters and boundary conditions are integrated to generate an optimal sail plan that assists the captain in selecting the optimal route and speed pattern to the next port.
The development is conducted as a joint venture between Offshore Monitoring Ltd, Advanced Computer Systems A.C.S. S.P.A., Global Maritime Services Ltd, Chalmers University of Technology and DNV GL, co-funded by the European Commission.
