ABB has secured an order with Washington State Ferries (WSF), the largest ferry operator in the US, to supply and integrate hybrid-electric propulsion systems for two hybrid-electric 160-auto ferries that initiate the owner’s ambitious system electrification programme.
With the first two ships scheduled for delivery from Eastern Shipbuilding Group, one apiece in 2030 and 2031, the contract includes an option for a third ferry. WSF has previously announced plans to build up to 16 ships by the end of 2040, as part of a ferry electrification programme targeting lower emissions.
ABB will supply and integrate end-to-end systems including power distribution, advanced energy management, and marine automation for ferries that will include the largest ship batteries installed in the US. Based on ABB Onboard DC Grid and PEMS power and energy management system, the hybrid-electric propulsion systems are expected to achieve substantially lower fuel consumption and operating costs than existing WSF vessels serving the same routes. Each ship’s 13.2 MWh energy storage systems will enable all-electric, emissions-free operations on short routes and in port.
The order builds on ABB’s early-stage involvement as the propulsion single source vendor in the WSF project, announced in 2024, with the contract amended to reflect the confirmed initial shipbuilding contract for two ships plus one option.
David Sowers, WSF System Electrification Program Administrator, said: “The Washington State Ferries System Electrification Program is the largest of its kind in the United States, and ABB’s continued involvement, secured through this new order, helps mitigate risk and ensure on-time vessel delivery. ABB’s state-of-the-art hybrid-electric propulsion systems demonstrate the company’s proven expertise in complex system integration. These systems will substantially reduce emissions and enhance operational reliability across the WSF fleet, advancing our long-term modernisation objectives and helping people and businesses thrive throughout the Puget Sound.”
The ABB systems on board are expected to reduce vessel noise and vibrations, increasing comfort for passengers and crew while minimising impact to local wildlife and coastal communities.
Bruce Strupp, VP Americas, ABB Marine & Ports division, added: “This contract marks another important step in our collaboration with Washington State Ferries. It reflects the trust placed in ABB’s hybrid-electric propulsion technology and our ability to deliver reliable, scalable solutions that support WSF’s long-term sustainability goals. We’re proud to continue helping WSF modernize its fleet to maintain reliable service and reduce environmental impact.”
