In mid-2022, Interlake Steamship Co. will welcome the first new ship to its fleet since 1981. The Middleburg Heights-based U.S. flag fleet is partnering with Fincantieri Bay Shipbuilding in Sturgeon Bay, Wisc., on construction of the bulk carrier. A news release stated that the ship is "believed to be the first ship for U.S. Great Lakes service built on the Great Lakes since 1983." In an email, Interlake president Mark W. Barker said this is the first fully integrated ship the company has built since 1981. It did a tug-barge conversion in 1998. The addition of the new ship will bring Interlake Steamship's fleet to 10 active vessels, as it will be extending the fleet instead of replacing a ship.

Commissioned by Interlake Steamship Company, based outside Cleveland, the 639-foot carrier capable of hauling 28,000 gross tons will be built in Sturgeon Bay, Wis., by Fincantieri Bay Shipbuilding. Both companies have 100-plus years of history on the Great Lakes. "We're proud to add it, announce it and ensure we serve our customers for years to come," Interlake Steamship President Mark Barker told the News Tribune. "It's being built with a lot of steel from Great Lakes steel mills to carry the products that help to do just that."

STURGEON BAY, WISCONSIN, April 9, 2019: A U.S.-flagged Great Lakes bulk carrier will be built for the first time in more than 35 years thanks to a historic agreement recently signed between The Interlake Steamship Company and Fincantieri Bay Shipbuilding.

The new River-Class, self-unloading bulk carrier is believed to be the first ship for U.S. Great Lakes service built on the Great Lakes since 1983.
