Alaska Class Ferry Project
Governor Sean Parnell announced in the fall of 2014 that the Alaska Department of Transportation and Public Facilities and Vigor Industrial have reached a final agreement to construct two Day Boat Alaska Class Ferries at Vigor Alaska in Ketchikan.The ferries will be 280- feet long, seat up to 300 passengers and carry 53 standard vehicles. Each ferry will feature bow and stern doors for quicker loading and unloading, fully enclosed car decks and controllable pitch propellers to maximize maneuverability and efficiency. A modified hull design will greatly improve traveler comfort during rough weather. The State was able to incorporate public input into the final design of the ferries while keeping the project within budget.The vessels are scheduled for delivery in late 2018.
Project Update: December 2017
All modules are now complete for the first of the two Alaska Class Ferries, all 23 modules are in place completing exterior steel construction on the MV Tazlina. Interior work continues with piping, painting and insulation in the engine room, electrical crews continue to terminate panels and equipment throughout the ship and continue trimming out lights, switches and receptacles in conjunction with the joinery installers.
The Tazlina was pushed outside on September 11th so the exterior hull could be sand-blasted before it was returned to the assembly hall where paint crews began applying primer and bottom paint. AMHS exterior colors were painted over most of the vessel in late October, and the nonskid weather deck paint was also applied.
The vessel was then moved 3/4 of the way outside on December 1st and the bow door, final module #6, was set and welded in place. With the Tazlina being moved partially out of the building, modules for the MV Hubbard can be joined together. Construction on modules for the second vessel are estimated to place operational acceptance of the second vessel in Spring 2019.

Project Update: April 2017
Construction has progressed into its 28th month with fifteen modules assembled and in place as well as four more under construction for the MV Tazlina. That leaves only two more modules left to be built for the first ship. Click on the image to begin a slideshow of the latest project pictures. The front half of the vessel was moved out of the building on November 20th 2016 and other recent accomplishments include:
- Engine room construction and placement
- Further assembly of the modules making up the aft section
- The aft section includes crew & passenger areas, engine room and car deck
- Mast installed onto the house top

Construction is progressing with fifteen modules assembled and four under construction for the first ship. Click on the image to begin a slideshow of the latest project pictures. There are currently 103 people assigned to the project, excluding management personnel, which is an increase of 9 from the 94 people that were assigned in October 2016. This has resulted in a high level of achievement over the course of the last several months. The front half of the vessel was moved out of the building on November 20th 2016 and other recent accomplishments include:
- Set Pilot House and Bridge Deck arrangement on assembly
- Set major equipment in spaces of forward half
- Made the ship weathertight for moving out of the building
- Engine room moved to the assembly hall
- Small crews and outfitting crew are working on close-out of spaces
- Pipe and steel are fabricating the aft section

Project Update: 07-29-16
Construction continues into the nineteenth month of the project with nine modules assembled and three under construction. Delivery of the vessel is due on October 15th, 2018. The AMHS construction team continues to address day to day detailed design issues and attend production planning meetings to keep the project moving forward. Elliott Bay Design Group (EBDG) has assisted with reviewing jacket water calculation, electrical questions, pilothouse alarm and UPS requirements, updated the mooring arrangement drawing and verified freeing port requirements.
Glosten continues to release a new version of the 3D model nominally every week. The pilothouse module outfitting was completed the last week in July. Major materials received on site in July include steel for hull structures, HVAC ducting, piping material, electrical panels, motor starters and anchor windlass controllers.
Since the last update, modules #9, #10, #11 have all been completed and placed on the vessel. Modules #13, #14 (the future engine room), and #18 are currently in progress, #5 and #23 have been built but are awaiting later placement.

Construction continues into its sixteenth month with crews from Vigor Alaska's shipyard in Ketchikan and the AMHS Project Team. Seven modules have been built, with four modules in place and the next two well underway. Other details have also been progressing, such as detail to the interior rendering of the vessels. The Project Team is utilizing computer based technology to coordinate the construction, movement and inventory demands of the project to avoid confusion and delays. The Team achieves this by producing a regularly updated computer animation showing the construction and movement of each module and the attachment of modules to the vessel. The use of technology is assisting to minimize potential problems while increasing efficiencies and coordination in the yard.
Each module is being built as a complete unit, with pipes, electric cable raceways, and other essential systems already installed. These are complete prior to the module being rotated upright, lifted into place and attached to the ship. Pipes, and raceways in previously attached sections must mate up exactly with pipes and raceways in future sections.
When moving the modules into place, they connect pad eyes with hand-operated winches. Pad eyes are a flat metal plate with a ring built in as one complete piece. The pad eyes are welded to the hull, giving the cranes and winches something secure to hold on to. Once lifted in place by cranes, winches are used to slowly tighten each piece together, until the whole section is precisely in place. The pad eyes are then removed and the attach point ground smooth.
Modules #2, #4, #5 & #23 are substantially complete. Work continues on module #1 which is waiting for the bow thruster tunnel ends to be faired into the hull. Module #3 was placed on the vessel during the month of January. Modules #7 and #8 have begun construction. Click on the image above to begin a slideshow of pictures depicting the current progress.

General construction progress has been inspected at Vigor Alaska's shipyard in Ketchikan, AK on October 26th by the AMHS Project team and Elliott Bay Design Group. Progress to date is looking good. The Day Boats are being constructed in modules that will be fit together from the hull upward, moving from bow to stern. Click on the image to the left to start a slideshow depicting the current progress.
Multiple modules are currently under construction. Plating and parts for module #7 have arrived and construction of this module will begin as work on the other modules continues. Steel construction of module #4 was recently completed and it has been lifted, rotated and placed on top of the vehicle deck of Module #2. Much of the shell plating has now also been completed on Module #1.
The bow thruster tunnel extension plates were rolled at Seattle Boiler Works, and have arrived. Workers are now welding the cylinders together, and performing final grinding. A wide variety of material is on site which will be used for outfitting the ship during the construction of the modules. Completion of the parts that comprise Modules #5 and 23 are now complete for the Day Boats and are stored outside the building hall.
