Important results from the project
The project´s objectives have essentially been met. All four deliverables are complete: a data-driven digital twin of a real ferry operation, validation against independent calculations, an operator-facing decision-support tool, and a pilot demonstration in California. The tool indicates around 10 per cent fuel savings and supports decisions on battery size, charging power and location. The project has also led to market entry into the US, today a priority market for Cetasol.
Expected long term effects
In the longer term, the project is expected to lower the threshold for electrifying small and medium-sized ferries. Operators gain a basis for decisions on battery size, charging power and location, while the tool delivers fuel savings in current operation. Correctly sized investments mean lower emissions and lower costs for waterborne public transport. The method transfers to other vessels on fixed routes, and Cetasol has established a position in the US market.
Approach and implementation
The project was implemented from November 2025 to June 2026 in five work packages: collection of operational data from the operator, building a digital twin of the operation, a simulation tool for timetable and speed optimization, a decision support for electrification and a pilot demonstration. The approach proved to be effective. Since the platform already existed, the work could be focused on usability and model accuracy. The schedule was met and the cooperation between the parties worked.
