1 WSF Hybrid Electric Ferry Conversion Project PSRC CMAQ Regional Funding Amy Scarton, WSDOT Assistant Secretary Washington State Ferries Matt von Ruden, Director of Vessel Engineering and Maintenance April 26, 2018

2 The Goal EXECUTIVE ORDER directs the Washington State Ferry (WSF) system to begin the transition to a zero-carbon-emission ferry fleet, including the accelerated adoption of both ferry electrification and operational improvements that will conserve energy and cut fuel use. The Target WSDOT Greenhouse Gas Emissions Vehicle Fleet 12% Stationar y Fuel Use 18% Ferry Vessels 67%

3 The Opportunity Class: Jumbo Mark II = largest 3 vessels Route: Seattle/Bainbridge and Edmonds/Kingston Propulsion: DIESEL-ELECTRIC (AC) Years Built: Reduce operating and maintenance costs 26% of the fleet s total fuel consumption Save up to 5 million gallons of fuel/year Operate on the busiest passenger routes with some of the shortest runs Ready for 20 year propulsion systems replacement, easily upgraded Only 20 years old, so potential 40 years of remaining service period Reduce WSF carbon emissions by ~25%

4 Challenges Multiple projects on 3 vessels, 4 terminals, with 3 utilities, each with different requirements and timelines Long lead time is brining the utility power to the docks Contracting strategy with currently funded preservation work while competing shipyard and terminal work Keeping current services levels while performing work Availability and flexibility of potential funding sources Lack of regulatory guidance and US experience

5 Next Steps and Potential Timeline Contingent upon funding, subject to change Completed research and feasibility studies (February 2018) Develop preliminary cost and risk ranges (Summer 2018) Hire system integrator, begin preliminary design (Fall 2018) Finish design, issue multiple requests for proposals (2019) Start vessel and terminal preliminary engineering ( ) First vessel retrofit ( ) hybrid mode achieved! Start terminal work and second vessel retrofit ( ) Additional vessels and terminals (2022 and beyond)

6 PSRC Funding Application Request WSF s request: $7 million in 2018 FHWA CMAQ Regional Funding The Project: Convert 2 Jumbo Mark II (JMII) vessels serving the Seattle-Bainbridge Island route to hybrid electric propulsion First step in WSF s transition to a zero-carbon emissions ferry fleet Needed to reduce GHG emissions, improve regional air quality, and move the Seattle-Bainbridge Island route toward meeting zero-carbon mandates 6

10 Questions? Amy Scarton and Matt von Ruden Director of Vessel Engineering and Maintenance Washington State Ferries

11 Initial Hybrid-Conversion Research Vessel Study: Elliott Bay Design Group developed a concept design to convert the vessels for full electric mode capability. The study also include a summary of worldwide vessel conversions and new builds incorporating hybrid technology, a review of potential costs and emissions reductions, and a regulatory review. Shore Infrastructure Study: WSF Terminal Engineering developed concept drawings, capacity analysis, and right of way analysis to install shore side improvements to support 4160 volt charging stations at Seattle, Bainbridge, Edmonds and Kingston terminals. All three affected utility providers (Seattle City Light, Puget Sound Energy, and Snohomish Co. PUD) participated. Ship-shore Interface Study: Glosten and Associates evaluated options for shorebased charging of electric ferries at WSF terminals. The study included the state of industry, requirements definition (e.g., safety, vessel motions, tidal fluctuations, and operating constraints), a concept design and cost review.
