Vigor Completes Ferry Repowering

By Mark Edward Nero

A repower of the M/V Columbia ferry has been completed in Portland by Vigor Marine, according to Seattle-based naval architecture and marine engineering firm Elliott Bay Design Group (EBDG).
EBDG, which has a long history of assisting ferry operators with services such as transportation studies, concept designs, capital budgets, security improvements and mid-life refurbishments, provided design services and ongoing owner support services for the M/V Columbia’s repower.

The Columbia was designed by EBDG’s predecessor firm Lockheed Shipbuilding, for the Alaska Marine Highway System, a ferry service operated by the Alaska state government.
“We’re intimately familiar with the vessel and its systems,” EBDG Project Manager Matt Williamson said. “The main engines were at the end of their useful life and the AMHS opted for replacing them, along with replacing or upgrading drive train components and auxiliary systems where it made economic sense.”

Williamson said that EBDG’s strong familiarity with the Columbia made his company “the natural choice” as the designer for this repowering project.

The Columbia has been the Alaska Marine Highway System’s flagship vessel for nearly 40 years, linking a number of inside passage communities. The 418-foot vessel can accommodate 625 passengers and features two vehicle decks with capacity for 134 vehicles.
Its homeport is in Ketchikan, Alaska.
