The Goal The Target

EXECUTIVE ORDER 18-01 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 Opportunity

Class: Jumbo Mark II = largest 3 vessels 26% of the fleet’s total fuel consumption

Save up to 5 million gallons of fuel/year

Route: Seattle/Bainbridge and Edmonds/Kingston

Operate on the busiest passenger routes with some of the shortest runs

Propulsion: DIESEL-ELECTRIC (AC)Ready for 20 year propulsion systems replacement, easily upgraded

Years Built: 1997-1998Only 20 years old, so potential 40 years of remaining service period

Reduce operating and maintenance costs

Reduce WSF carbon emissions by ~25%

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

Next Steps and Potential TimelineContingent 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 (2019-2020)

• First vessel retrofit (2020-2021) “hybrid” mode achieved!

• Start terminal work and second vessel retrofit (2021-2022)

• Additional vessels and terminals (2022 and beyond)

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

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 shore-based 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.
