August 14, 2019

Fincantieri Bay Shipbuilding and The Interlake Steamship Company hosted a ceremonial first-cut-of-steel event Wednesday, celebrating the historic start of construction on the first U.S.-flagged Great Lakes bulk carrier built in more than 35 years.

After careful preparation by Fincantieri Bay Shipbuilding’s blast and prime team, its fabrication team prepped and then cut the steel with automated precision within the shipyard’s largest fabrication building in Sturgeon Bay, Wisconsin.

“The first cut of steel is a major milestone that signifies we, along with Fincantieri Bay Shipbuilding, are ready to begin production on this historic project,” says Interlake President Mark W. Barker. “We are extremely proud to build our company’s first ship since 1981 on these freshwater shores with the hardworking women and men who help power our industry and with American-made steel from the iron ore we carry on our U.S. flag fleet vessels. It’s a true Great Lakes success story.”
