Built in 1973, by Main Iron Works of Houma, Louisiana (hull #281) as the Venturer 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.

However, over the years many changes came to Interstate Oil, when a company called Southern National Resources (also known as SONAT Marine) acquired Interstate Oil Transportation. Eventually a group of managers at SONAT Marine offered to form a partnership to raise the funds necessary to purchase the SONAT Marine subsidiary. These eleven partners included some who had worked for IOT since the 1950's. On April 14th, 1987, Maritrans Partners of Tampa, Florida was formed. And, assumed control of SONAT's tug and barge operations in Philadelphia, Pennsylvania and Tampa, Florida.

However, in March of 1989. The Exxon Valdez ran aground in Prince William Sound near Valdez, Alaska. 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 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 transport 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 companies established operations in the area. They included Bouchard Transportation of Melville, New York and Vane Brothers of Baltimore, Maryland.

In 1998, the tug was acquired by the K-Sea Transportation Partnership of East Brunswick, New Jersey. Where she was renamed as the Coral Sea.

In 2010, the tug was acquired by Pheranzy Gas Limited of Lagos, Nigeria. Where she was renamed as the Ugonwaafor 2.

Powered by two, EMD 16-567-6 diesel engines. With Lufkin 2520 reduction gears, at a ratio of 3.487:1. She was a twin screw tug, rated at 3,280 horsepower.

Her electrical service was provided by one, 75kW Delco E5764HA, 225/450 generator set. And one, Delco E773344 75kW, 225/450 generator set. The tug's capacities are 56,413 gallons of fuel oil, 1,050 gallons of lube oil, 435 gallons of hydraulic oil, 2,842 gallons of potable water, 21,966 gallons of ballast water, 2,848 gallons of slop oil.

Her towing gear consisted of a single drum, Almon Johnson 225, towing winch. Outfitted with 2,200(ft) of 2(in) towing wire. Driven by a single, Detroit Diesel 6-71 engine.
