As with the first two vessels, ABB will equip the third vessel with an integrated hybrid-electric power and propulsion solution cantered on Onboard DC Grid and PEMS Power and Energy Management System. With Onboard DC Grid maximizing power distribution efficiency and energy storage integration, PEMS continuously manages available power sources to optimize energy use for vessel operating conditions.

This reduces reliance on diesel engines, thereby helping to reduce fuel consumption and emissions. The 13.2-megawatt-hour energy storage system integrated by ABB is designed to enable all-electric, zero-emissions operations on short routes and in port.

ABB’s scope of supply across the first three vessels also includes integrated marine automation, propulsion drives and motors, transformers, low-voltage systems, uninterruptible power supply systems, remote diagnostics, propulsion shafting, propellers, steering gear and rudders, in addition to engineering and commissioning support.

Washington State Ferries’ electrification program targets emission reductions of 76% in carbon dioxide, 75% in sulphur oxides, 94% in nitrous oxides, and 90% in particulate matter by 2040 – and ultimately envisions an emission-free fleet by 20505.

The order further builds on ABB’s earlier involvement as the propulsion single source vendor in Washington State Ferries’ project, announced in 2024, with the contract amended to reflect the confirmed initial shipbuilding contract for two ships plus one option.
