Built in 2010, by Washburn and Doughty Associates of East Boothbay, Maine (hull #98) as the ATB Mary Ann Moran for the Moran Towing Corporation of Greenwich, Connecticut.

An ATLANTIC IV class ATB, designed by Ocean Tug & Barge Engineering. She was the fourth Articulated Tug built for Moran by Washburn and Doughty.

The unit was constructed for service on a charter to ConAgra grain products, between New Orleans, Louisiana and Puerto Rico. A charter that was being serviced by a conventional tug and barge unit. However, the use of an ATB was found to be more economical with regards to time underway and fuel efficiency. The Mary Ann Moran is named for the wife of ConAgra Grain executive Gary Redmann.

Powered by two Tier II compliant EMD 12-71OG7C T2s diesel engines with Lufkin RHS2500HG reduction gears at a ratio of 4:1, turning via 10(in) shafts, two five bladed, 115(in) Rolls-Royce New Generation propellers for a rated 5,100 horsepower. The only difference between the four tugs is that the first two of the class were outfitted with pairs of 12 cylinder EMD 645-series diesel engines.

Her electrical service is provided by two of 125 kW Marathon generators, driven by two John Deere 1,800 rpm engines. To meet SOLAS requirements, the tug is outfitted with a third keel cooled 65 kW Marathon emergency generator above the main deck. If the two primary generators suffer a power loss, an Industrial Power Systems emergency switchboard detects the power loss and automatically activates the emergency genset.

The tug's capacities are 142,000 gallons of diesel fuel, 16,000 gallons of potable water, and 68,000 gallons of ballast water.

Her deck equipment consists of a Markey CEWP-90, 40 horsepower electric capstan mounted on the stern, and a Markey CEW-60, 15 horsepower electric capstan mounted on the bow. The tug is fitted with an INTERcon "C" series coupler system with 34(in) rams.

She is married to a 400(ft), 27,000 DWT dry bulk barge, the Virginia . Which was built in 1982, by Galveston Shipbuilding of Galveston, Texas. The barge was converted at Gulf Marine Repair of Tampa, Florida for service as an articulated barge.
