Together with Kvaerner Masa-Marine (today Vard Marine) we developed the concept for the current Great Lakes heavy icebreaker, USCGC Mackinaw, together with the United States Coast Guard. The vessel was delivered in 2006 and features twin Azipod propulsion with a double-acting hull capable of breaking ice in both ahead and astern directions.
