The Integrity was constructed in 1996 by Bay Shipbuilding of Sturgeon Bay, WI, as a self-unloading cement barge for American Transport Leasing of Muskegon, MI. The barge was to be operated by Andrie, Inc. of Muskegon under a cargo contract to Lafarge Holcim.
Integrity was paired with the tugboat Jacklyn M. in mid-1996, and the pair entered service for Lafarge on August 6, 1996, departing Sturgeon Bay, Wisconsin, for Alpena, MI, to load cement. Upon the pair entering service, the older steamers E. M. Ford and S. T. Crapo were laid up for the final time at the end of the season.
The tug was renamed G. L. Ostrander in 2004 after an executive at Lafarge.
The Integrity / G. L. Ostrander continue to serve Lafarge cement, being operated and managed by Andrie, Inc. of Muskegon, MI.
