Construction

The Mark W. Barker was constructed in 2022 by Fincantieri Bay Shipbuilding at Sturgeon Bay, Wisconsin, as a self-unloading river-class bulk carrier for the Interlake Steamship Company. She was the first self-powered American freighter to be constructed for Great Lakes service in almost 40 years, the latest being the Columbia Star [American Century, 2006;] of 1981.

The Barker was designed to be a unique and versatile ship, being designed to River class dimensions to allow her to transit confined waterways, with a forward mounted self-unloading boom for added versatility. Her self-unloading system will consist of a single hold belt leading to a forward loop-belt system that feeds a 250′ deck-mounted boom. Her holds will not have any slopes installed, and will utilize a pair of front-end loaders to move cargo to the conveyor belt. She will feature five large cargo hatches, leading to her cargo hold. The new ship will be environmentally friendly, being built to EPA and IMO standards. She features bow and stern thrusters, being pushed by a single controllable pitch propeller followed by a single flap rudder.

Her Story

The Mark W. Barker was constructed in 2022 by Fincantieri Bay Shipbuilding at Sturgeon Bay, Wisconsin, as a self-unloading river-class bulk carrier for the Interlake Steamship Company. She was the first self-powered American freighter to be constructed for Great Lakes service in almost 40 years, the latest being the Columbia Star [American Century, 2006;] of 1981.

The keel for the Mark W. Barker was laid in ceremonies on June 23, 2020. The partially-completed hull was floated from drydock for the winter on December 17, 2020, to allow ships in winter layup to be drydocked. A large portion of the hull was completed, at approximately 440′ long. The hull was moved to a berth at Bay Shipbuilding for the winter. She was placed back in the graving dock in the spring to complete the hull, which was launched on October 28, 2021, and moored at a berth in the shipyard. At the time of launch, her exterior hull was almost entirely complete, and work on the interior of the vessel was quickly progressing.
