This tug was built in 1982 by Bay Shipbuilding as the Amoco Michigan for Amoco Oil. In 1985 she was transferred to Coastwise Trading Company, a subsidiary of Amoco, and renamed Michigan. She was managed by Keystone Shipping of Bala Cynwyd, Pennsylvania. In 2010, the Michigan was sold to Chicago Marine Asset Management, and the following year was acquired by U.S. Oil of Appleton, WI. In 2015 she was converted to an articulated tug with the addition of an Articouple system.
Michigan is paired with the tank barge Great Lakes, and operates across the Great Lakes carrying various liquid products, usually out of Green Bay, WI. The pair is operated by Andrie Inc. of Muskegon, Michigan.
