An ATLANTIC IV class Articulated Tug and Barge (ATB). Designed by Robert Hill of Ocean Tug and Barge Engineering of Milford Massachusetts. She was the fourth Articulated Tug built for the Moran Towing Corporation 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.

The tug is fitted with an INTERcon "C" series coupler system with 34(in) rams. And, 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, fixed pitch, new generation propellers. For a rated 5,100 horsepower.

Her electrical service is provided by two of 125 kW Marathon generators. Driven by two John Deere diesel engines. To meet SOLAS requirements, the tug was 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.

She is "married" to a 400(ft), 27,000 DWT dry bulk barge, the Virginia. Which was constructed 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.
