Elliott Bay Design Group (EBDG) was recently selected by Vigor Industrial subsidiary Vigor Fab as the engineering firm that will provide functional design for the new hybrid-electric Olympic-class Ro-Pax vessels for Washington State Ferries (WSF).
EBDG is responsible for redesigning the vessels to accommodate the major change in propulsion type without disrupting structural components.
The ferries will operate on all-battery power during crossings or can revert to a hybrid, diesel-electric propulsion if required. Battery recharging will typically occur dockside at the terminals during offloading/loading procedures.
