Riders' Questions for Glosten

The Ferry Committee solicited riders questions and comments to submit to the naval architects in time to prepare responses for the November 2, 2017 Ferry Replacement Public Forum. These are the questions received and compiled by the Guemes Island Ferry Committee

1.  Will reliability of ferry options be considered? If so, will the design include redundancy as a means to achieve reliability? If so, what elements of the electrical and drive systems will be redundant? Will mean time to failure (MTTF) and mean time to repair (MTTR) numbers be considered as part of the study?

2.  In comparing ferry options, will Life Cycle Cost be considered? If so, will detailed numbers be presented for review?

3.  Is an aluminum ferry being considered?

4.  Is a catamaran style ferry being considered?

5.  What are the priorities in evaluating types of propulsion systems?

6.  Please address battery technology for an electric ferry, and advancement in that technology in the past few years. How many batteries will be needed for a new Guemes, what is their carbon footprint, lifespan and disposal after depletion?

7.  If an electric ferry is chosen, will it need to be recharged between runs? If so, will the time necessary for recharging require a change to the present ferry schedule, and what will be the method for connecting the ferry to shore power? Will that method require additional crew?

8.  If an electric ferry is chosen, what provisions will/should be considered so that the vessel and up-shore facilities can adapt to improvements in battery technology over the life of the ferry?

9.  Will an update to the Elliott Bay Design Group’s 2013 study for a refurbished ferry be part of Glosten’s work? 

10.  Is Glosten looking at a larger vessel? Why?

11.  Is Glosten studying an increase in throughput - that is to increase the numbers of vehicles carried per hour, per peak period, or per day? Has Glosten been told to maintain something close to the current schedule or are they free to consider, say, one larger run per hour or one massive run per day?

12.  Given that there is a limit to how much improvement can be made to load times (without significantly modifying docks and ramps) and travel times, how will Glosten offset the increased load times that come with increased capacity?  Is Glosten looking at changes to ticketing and loading procedures as a way to increase throughput?

13. Has Glosten been asked to consider the comfort of walk-on passengers?

14.  Will the riders have an opportunity to study and comment on the design before it is finalized?

15.  Who will name any new vessel?

16.  What provisions will be made for bicyclist and pedestrians, so they don't have to breathe car exhaust while loading and unloading?

17.  In studying the electric ferry option, has it been determined that Puget Sound Electric will need to upgrade their infrastructure to allow for rapid recharging of the ferry batteries? If so, has that cost been compared to that of an on-shore battery similar to the Ampere project?
