Elliott Bay Design Group Selected To Design Hybrid-Electric Ferry For Washington State

By | 2019 Newsletter week 44 | No Comments

Elliott Bay Design Group (EBDG) was selected by Vigor Fab as the engineering firm that will provide functional design for the new hybrid-electric Olympic Class ferries 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.

Earlier this year, Washington State’s Legislature authorized a contract extension for Vigor to build up to five hybrid-electric versions of their 144-vehicle Olympic Class.  The new-build authorization is a direct result of the 2040 Long Range Plan that identified the initial aspects of vessel and terminal electrification.  EBDG was a participant of the plan and is now leading the effort for an additional, supporting addendum – the WSF System Electrification Plan.  The System Electrification Plan will identify a detailed plan for deploying hybrid-electric vessels throughout the ferry system.

More than half of Washington State Ferries’ 23-vessel fleet is scheduled to be retired by 2040. The ferry system needs 16 new vessels in the next 20 years, including 13 ferries to replace vessels due for retirement and three additional vessels to fill in when other ferries are out for maintenance and to respond to growth.

Norled Confirms Vessel No. 3 And 4 Of LMG 120-DEH Design

On 1 August 2018 Norled has announced the contract for the construction of two Double Ended Diesel Electric Hybrid ferries based on the LMG 120-DEH design to be built at Remontowa Shipyard. These two sister ships comes in addition to the two first units for which the shipbuilding contract was signed in July.

These two sister ships will operate on the Mannheller-Fodnes route and, as compared to the two first ones intended for the Festøya-Solavågen connection, will feature two modifications. Since the Mannheller-Fodnes route is shorter, the capacity of the battery pack will be reduced by approx. 20%. At the same time, the vessels will be certified to carry more passengers with the maximum being 395 persons.
