Her Story

Amoco Michigan was constructed in 1982 as a tugboat by Bay Shipbuilding at Sturgeon Bay, Wisconsin, for Amoco Oil Company of Indiana. She was paired with the barge Amoco Great Lakes after completion, which was built by the same shipyard. The pair were not originally an articulated tug-barge unit, but rather lashed together using a cable and winch system. Amoco Michigan / Amoco Great Lakes entered service in September 1982.

In 1985, the pair were sold, and Amoco was removed from both vessels’ names. Amoco Michigan was renamed Michigan. The tug-barge pair were operated by Keystone Shipping.

In 2010, the pair were acquired by Chicago Marine Asset, retaining their names.

Michigan and her barge Great Lakes were sold once again in 2011 to their present owner, U.S. Oil Inc. of Appleton, Wisconsin. Management of the vessels was contracted to Andrie, Inc., of Muskegon, Michigan.

In 2015, Michigan was retrofitted with an Articouple ATB coupler pin system, and the barge Great Lakes was retrofitted with the receiver, making the pair an actual Articulated Tug-Barge unit. Michigan / Great Lakes continue to be active in the petroleum trades on the Lakes, transporting petroleum products between Green Bay, Wisconsin, and several other Great Lakes ports.
