Built in 1972, by Main Iron Works Incorporated of Houma, Louisiana (hull #255) as the Navigator for the Interstate Oil Transportation Company of Philadelphia, Pennsylvania.

At the time, the Interstate Oil Transportation Company operated two fleets. Their Northeast Fleet, which was referred to as the "Green Fleet." Operated in Philadelphia, Pennsylvania. And their Southern Fleet, which was referred to as the "White fleet" which operated out of Tampa, Florida.

In 1981, the Interstate Oil Transportation Company was acquired by the Southern National Resources Company of Birmingham, Alabama. The new company was named the SONAT Marine Company Incorporated of Birmingham, Alabama. Where the tug retained her name.

In 1987, the SONAT Marine Company was acquired by the the Maritrans Operating Partnership of Tampa, Florida. Where the tug retained her name. Maritrans was formed by group of managers from the SONAT Marine Company. Who offered to form a partnership to raise the funds necessary to purchase the company. These eleven partners included some individuals who had worked for the Interstate Oil Transportation Company since the 1950's.

In March of 1989, the Exxon Valdez ran aground in Prince William Sound near Valdez, Alaska. And in 1990, the Oil Pollution Act of 1990 was passed calling for the double hulling of all petroleum carrying vessels by January 1st of 2015. As well, as other stipulations that effected Maritrans including manning, preparedness, and spill prevention. Maritrans filed suit to fight the stipulations set fourth by OPA '90.

By the mid 1990's, the Maritrans Operating Partners had begun to consolidate its business. By first, backing out of the black oil trade, and carrying only petroleum products and petrochemicals. The phosphate trade, and local transportation in Baltimore, Maryland that was part of the Harbor Towing subsidiary did not fit into Maritrans's new business model. As Maritrans backed out local transportation companies emerged, and established operations in the area. They included the Bouchard Transportation Company of Melville, New York and the Vane Brothers Company of Baltimore, Maryland.

In 2006, the Maritans Operating Partnership was acquired by Overseas Shipholding Group of New York, New York. Where the tug was renamed the OSG Navigator.

In 2017, the tug was phased out go active service. And was scrapped.

She was outfitted with an INTERcon coupler system. The tug was powered by two, sixteen cylinder, EMD 16-645-E5 diesel engines. Turning two, cast steel, fixed pitch propellers. She was a twin screw tug, rated at 5,600 horsepower.

Her electrical service was provided by two, 99kW generator sets. The tug's capacities are 118,349 gallons of fuel, and 32,757 gallons of water.
