Does anyone know when MV Hyak is scheduled for her major overhaul and maintenance project? Still no. Perhaps when WSF posts the maint schedule for the next fiscal year there will be more info. |

Hey, what do you know, it was posted on the first.  It isn't going to happen next year. The Hyak isn't going to be out of service long enough for a major overhaul... At Eagle Harbor from Dec 5th to January 1st and again February 6th to Feb 26th with her annual inspection on Feb 20/21. www.wsdot.wa.gov/ferries/business/contracts/UpcomingProjects.aspxAnd I forgot I had this...original clipping of the Hyak's arrival from the now sadly defunct Seattle PI. |

I don't think we've even got that on the boats yet. |

I actually hope the Hyak stays as original as she is now. IMO, it's a nice change. I love vintage things and despite its modifications, I love the fact that its interior is much the same now as it was in 1967. And I didn't mind those seats  |

In the 2011-13 budget a hefty chuck of change ended up allocated to the Hyak compared to the other boats for preservation ($7M). Previous house versions though had allocated her up to $14M in preservation what documents called a "rebuild". The following document lists what was allocated by boat on page 38. Anything beyond 2011-13 is essentially "planned" though. leap.leg.wa.gov/leap/Budget/leapdocs/stLEAPDoc2011-2_0422.pdf(this is listed as a house doc but was enacted as is per the combined bill) A detailed list of each WSF capital budget item starts on page 36 |

Interesting bit of info on the Hyak!
G:\RFI\FY 2011\ Page 1 of 2 Rev 6/27/11
HYAK PROPULSION\RFI\001
REQUEST FOR INFORMATION
RE: HYBRID DIESEL - ELECTRIC PROPULSION
The Washington State Department of Transportation Ferries Division, operating as Washington State Ferries (hereinafter called “WSF”), issues this Request for Information (RFI) to develop a scalable hybrid diesel-electric propulsion system for the M.V. Hyak, a Super Class ferry.
Like all state governments across the nation, Washington State is facing unprecedented shortfalls in revenue. Further, recent projections in fuel prices have led to a $74 million increase in fuel costs. Diesel fuel is now estimated to become 29% of WSF’s entire operating budget by the next fiscal biennium.
Consequently, WSF is placing an even higher priority on maximizing fuel economy for a planned propulsion upgrade for the Hyak. Further, with Washington State’s leading role in clean air initiatives, WSF views increased fuel efficiency as a means to decrease harmful exhaust emissions.
The Hyak is one of the four Super Class ferries built in the late 60’s to 46 CFR Subchapter H (Passenger Vessel) standards as enforced by the US Coast Guard. The Hyak is 382’2” long and carries 144 autos and 2,500 passengers. While the other three Super Class ferries were renovated in 1991 (M.V. Elwha) and 2005 (M.V. Kaleetan and M.V. Yakima), the Hyak was not renovated.
At a minimum, WSF desires to replace the Hyak’s old Ward-Leonard style DC-DC propulsion system with a state of the art AC-AC diesel-electric plant. For the Hyak’s 6.1MW of installed propulsion power, the load profile typically goes from 60% for a 20-50 minute crossing to 10% while loading at a dock for 20-30 minutes. Because of these large and regular fluctuations in propulsion power load, WSF believes the latest hybrid technologies could prove quite beneficial.
Additionally, with due regard for safety, failure mode concerns often lead to an extra generator on-line from what would be ideal for fuel efficiency. Thus, energy storage technologies could serve as “spinning reserve” allowing for the most efficient number of diesels to be run within their optimum load range. The existing DC-DC propulsion plant, while able to operate at variable speed, requires running all four diesels through an entire operating day (typically 18 hours).
Various hybrid technologies will be strongly considered for the project specifications, including combinations of: The latest battery or other energy storage technologies Variable speed diesels driving variable speed AC Generators DC distribution of propulsion power Auto-start power management systems Bi-directional power flow with the ship service bus (480 VAC)
Given the 11 other diesel-electric vessels in its 23 vessel fleet, WSF is also interested in hybrid technologies that could be scalable to other future propulsion upgrades. Therefore, Desired Operating Criteria for the Hyak’s propulsion system include:
Fuel consumption to be less than the existing system Lower exhaust emissions: NOx, SOx, CO2, PM
Lower maintenance costs
Upgrade to modernize Hyak’s propulsion system for the next 25 years. Existing 16cyl EMD 645 diesel prime movers to be reused
16.5 knot operating speed
Vehicle and passenger capacity shall remain unchanged
Stopping distance shall be no greater than existing
This RFI is an informal outreach to determine the extent and nature of interest in the above-specified hybrid propulsion system. When WSF has determined how best to proceed, it will publish a formal notice for a competitive Request For Proposals (RFP) process. Respondents to this RFI will receive a copy of the RFP notice. However, response to this RFI is not a prerequisite to participate in the RFP process.
Responses to this RFI should be no more than ten (10) written pages in length, but may also include videos, photos, drawings or sketches to assist in describing the integrated propulsion system. Interested parties should send responses no later than Friday, July 22, 2011 to the address listed below. The responses are non-binding. WSF also desires discussions with interested parties during the period from August 1 through August 12, 2011. Please contact the WSF representative below to schedule a presentation.

The way I read it, that isn't "maximum" operating speed; just operating speed. The new system needs to make a service speed of 16.5 knots; anything above that is considered gravy (and most systems have a little "left in the bag," so to speak).

Hmm, interesting. I know Foss has a hybrid tug they've been publicizing quite heavily.
Hybrid systems are often times heavier though, especially when you throw in the batteries. I know the supers are top heavy but how are they on weight over all? I know they are little low in the freeboard department already.

Weren't the Supers rated for 20 knots when built? Seems at 17kts average speed, that isn't quite at full. Interesting nonetheless, would love to see one of those vessels go full hilt...

They were capable of 20 knots at the outset, yes. But that was 44 years ago. (I last saw the Hyak running at 20 knots sometime around 2003-4.) I'd say 17 knots is about average full speed on the old girls anymore. I suspect the equipment could probably deliver a little more, but I also suspect it would protest briefly and then fail catastrophically. Under the right circumstances, I have seen the Elwha achieve 23.4 knots without any real assistance from the current. That was with all four engines on line and the drive motors turning over at about 25 RPM past what is currently considered maximum speed. The boat was also shaking hard enough that I was getting nervous about all that glass down below. It's my understanding that the Supers are operated in the neighborhood of the "efficiency point" on the fuel consumption curve--we'd have to pour a LOT more coal to it to get a little more speed, and those four-engine monsters are pretty thirsty as it is. |

Speed tests? |

I was on Elwha once, about 12+ years ago, on the late night direct sailing from Orcas to Anacortes, and she had all of her engines cranked up - made the normally 50 minute crossing in 40 minutes flat out. Yeah, she was vibrating a lot the entire trip. I don't think we were doing 23 knots, but it must have been at least 19 or 20 knots. Have no idea why they were running her that fast, but it was kind of cool.

Speed tests? It was a speed trial. We had vendors aboard who were working up a bid package, and they asked the chief engineer "so what'll she do?" He showed them. ;D |

I am suprised how fast those WSF go. Last time I was at Anacortes I was suprised how fast the Sealth came flying out of Anacortes on our way to Friday Harbour.

I was on the Chelan a few summers back when we had the current running with us. She was going 20-21 knots and that is fast on an Issaquah--and also well over her rated speed. Needless to say, it was one heck of a current! ;D I've also been on the Hyak when they had a medical emergency onboard and had to make haste for Seattle. She was doing her 20 knots + and vibrating mightily the whole time, but still impressive. |

I've found the best way to get extra speed out of a state ferry is to call the engine room and ask, "hey, Chief, what do you know about delivering babies?" ;D |

From my knowledge, they have the most hydro-dynamically efficient design. Any vessel that leaves minimal wake behind is likely regarded as being very efficient. However, their fuel consumption efficiency is another story, lol.

The Supers have the fastest hull of any of our boats, as far as I know. Unfortunately, the narrow beam causes a lot of problems for the loading and unloading end of the game.

I do not like being parked in the sides because of the narrow lanes on them. I seem to frequently get parked next to somebody who has left too much space next to the wall. People don't realize that the lines are there for a reason until it's too late to do anything about it. It sure is fun being on a Super when it makes a sharp turn though!

Last time I took the Kaleetan we went a little sharp around that point entering Rich Passage and she took to hanging on a roll like a champ. Had a pretty good list to her for a little bit. LOL
