Her Story
The G. L. Ostrander was built in 1976 by Halter Marine of Pierre Part, Louisiana, as the push tug Andrew Martin for Andrew Martin Marine Sea Service. She entered service for Andrew Martin Marine in 1976.
In 1990, the Andrew Martin was sold to River Marine Contractors, being renamed Robert L. Torres. The Torres was repowered with a new Caterpillar diesel engine in 1991. She was sold again in 1993 to Jacklyn Shipping of Tampa, Florida, being renamed Jacklyn M. in 1994.
In 1995, Lafarge acquired the Jacklyn M., bringing her to the Great Lakes where she would have her upper pilothouse raised and be equipped with a Bludworth ATB connection system. She was paired with the newly-constructed self-unloading cement barge Integrity in 1996, and the pair entered service on August 6, 1996, departing Sturgeon Bay, Wisconsin, for Alpena, Michigan, 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 Jacklyn M. was renamed G. L. Ostrander in 2004, after an executive at Lafarge. Operations continued as normal.
The Integrity / G. L. Ostrander continue to serve Lafarge, now Holcim cement, being operated and managed by Andrie, Inc. of Muskegon, Michigan.
