ABB to Power Washington State Ferries’ First Hybrid Newbuilds

ABB Secures Strategic Ferry Hybrid Propulsion Contract

ABB has won an order from Washington State Ferries (WSF), the largest U.S. ferry operator, to supply and integrate hybrid propulsion systems for two new 160-car ferries. The vessels will be built by the Eastern Shipbuilding Group, with planned deliveries in 2030 and 2031. The contract also includes an option for a third ferry.

ABB integrates hybrid propulsion and control systems for WSF ferries, enabling full-electric operation and lower fuel consumption.

Expanding Ferry Electrification for Emission Reduction

WSF has announced plans to construct up to 16 hybrid ferries by 2040 as part of its electrification strategy. ABB’s integrated systems will support this initiative by providing distribution, advanced energy management, and ship automation. Moreover, these ferries will feature the largest shipboard batteries ever installed in the United States.

Advanced Energy Management and Operational Efficiency

ABB’s hybrid propulsion system combines onboard DC grids with the PEMS (Power and Energy Management System), enabling significant fuel savings and lower operating costs compared with existing WSF vessels on the same routes. Each ferry will include a 13.2 MWh energy storage system, allowing short-distance and port operations to run fully on electric power with zero emissions.

ABB’s Proven Expertise in Complex Systems Integration

ABB has participated in the WSF hybrid project as the single propulsion system supplier since 2024. The company’s deep experience in industrial automation and control systems ensures seamless integration of power distribution, PLCs, and DCS, which maximizes reliability and reduces project risk. David Sals, WSF Electrification Project Manager, emphasizes that ABB’s hybrid propulsion technology enhances fleet modernization while supporting Puget Sound communities and businesses.

Industry Insights and Author Commentary

The U.S. ferry electrification market is emerging as a benchmark for sustainable maritime operations. As hybrid propulsion technologies evolve, operators benefit from reduced emissions, lower fuel costs, and improved reliability. ABB’s approach demonstrates how industrial automation principles, including sophisticated control systems and energy management, can optimize complex marine applications. Moreover, this project reflects a growing trend of integrating factory automation expertise into maritime electrification solutions.

Applications and Use Cases

These ABB hybrid propulsion systems are ideal for short-sea shipping, passenger ferries, and port operations. Marine engineers can leverage integrated PLCs, DCS, and energy management systems to optimize power flow, reduce emissions, and achieve cost-effective, reliable fleet operations.
