The Mark W. Barker came to life at Fincantieri Bay Shipbuilding in Sturgeon Bay, Wisconsin marking the first self-propelled, self-unloading cargo vessel built for the Great Lakes maritime trade in over 35-years.
The 639-foot bulk carrier was constructed with U.S. steel from U.S. iron ore mines in Minnesota and Michigan and transported by U.S. vessels to the Wisconsin shipyard.The vessel is a tremendous success story for U.S. shipping and continuing the long-standing legacy of Wisconsin shipbuilding.
Unlike most Great Lakes freighters, the Mark W. Barker has a square-shaped, flat-bottomed cargo hold instead of a traditional V-shaped angled bottom that funnels bulk cargo onto conveyer belts for offloading. The combination of larger hatch openings and additional cargo hold space was designed with future cargoes in mind to include non-free-flowing bulk material such as wind-turbine blades.
In addition, the unloading boom is located on the forward end of the ship, offering flexibility for cargo operations in congested ports. Many Great Lakes customers find the forward boom more advantageous to allow placement of in preferred areas for access at their docks.
This highly versatile River-Class vessel highlights Interlake Steamship Company’s long-term commitment to corporate social responsibility and sustainability. All aspects of the vessel have been designed to ensure that it will have a low environmental impact to the Great Lakes and to those who work aboard.
The new vessel will continue to serve the U.S. Great Lakes maritime trade for years to come delivering the cargo essential to the North American economy.
