The project is aimed at developing technological solutions for the sustainable growth of maritime transport, and, primarily, for a significant reduction of the emission of GHG and of other climate-affecting pollutants through improved efficiency, smarter energy management, the introduction of new, low carbon, fuels, and augmented electrification. Such a transformation requires: i) increased efficiency of the initial design thanks to the increased digitalization; ii) better management of the ship and of its subsystems during open and closed water operations, thanks to improved situational awareness and ports logistics; iii) cutting edge solutions and materials, such as innovative coatings which improve the efficiency preserving the marine environment; iv) integrated use of sensors and digital technologies to support the ship automation; v) decision support system in for the operation management. Owing to the peculiarities of the sea environment, data from external sources, such as weather observations and forecasts as well as sea-state conditions or traffic information, local and at the arrival port, have to be accounted for in the decision process.
