Alaska Ferry contract for Thordon Bearings

Thordon Bearings will supply its COMPAC propeller shaft bearing system to two Alaska Ferry newbuilds under construction at the Vigor Industrial shipyard in Ketchikan.

The twin-screw, 280ft long Alaska-class ferries will each have capacity to carry 300 passengers and 53 standard vehicles and feature fully enclosed vehicle decks with bow and stern doors for quicker loading/unloading.

Craig Carter, director of marketing and customer service, Thordon Bearings  said: “These vessels, thought to be the first built in Alaska for use in Alaska, are a significant step forward for the Vigor Industrial shipyard and we are delighted to be associated with this new class of arctic ferry. The COMPAC propeller shaft bearings will ensure these vessels can operate with zero risk of any oil discharges into a very ecologically sensitive area.”

Thordon Bearings will deliver the Environmentally Acceptable Lubricant (EAL)-compliant system for shaft diameters of 267mm, with delivery to the first vessel in the series due later this year with the second following in early 2016.

Both vessels are due to be delivered to Alaska Marine Highway System, part of the Alaska Department of Transportation and Public Facilities, in 2018 for subsequent operation as day boats along the Lynn Canal route between Juneau, Haines and Skagway.

Thordon’s seawater lubricated bearings are already installed on Alaska Marine Highway System’s ferries Matinooska, Tuskamina and Kennicott.
