Elliott Bay Design Group (EBDG), a naval architecture and marine engineering firm with offices in Seattle, New Orleans and Ketchikan, Alaska, today announced the completion of the M/V Columbia repower. EBDG provided design services and ongoing owner support services for the ferry's repower, which was performed by Vigor Marine in Portland, Ore. "The Columbia was designed for the Alaska Marine Highway System (AMHS) by EBDG's predecessor firm, so we're intimately familiar with the vessel and its systems," said EBDG Project Manager Matt Williamson.
