Wärtsilä Tapped for Zero Emission Ferry

Wärtsilä will supply the electric propulsion system for three fully bat- tery-electric, high-speed ferries that will operate in the San Francisco

Bay area. The zero-emission vessels will be the ? rst full electric high- speed ferries to operate and be built in the USA. The order with Wärt- silä has been placed by the shipyard All American Marine (AAM), on behalf of San Francisco Bay Ferry. Wärtsilä’s scope of supply is for the full electric propulsion system inculding the energy and power man- agement system (EPMS), the integrated automation system (IAS), bat- teries, DC Hub, transformers, E-Motors, and the shore power supply.

The equipment is scheduled for delivery commencing in 2026, and the ? rst vessel is expected to join the ferry ? eet in early 2027.
