Built in 1962, by Jakobson Shipyard of Oyster Bay, New York (hull #408) as the Patricia Moran for the Moran Towing Corporation of New York, New York.
In September of 1999, the Patricia Moran underwent a conversion at the Hendry Corporation Shipyard of Tampa, Florida. Original design work on Moran's conversions was performed by naval architect Paul Gow.
The redesgined tugs were dubbed the MORtrac class tugs. The Patricia Moran was the fourth MORtrac conversion, and the fifth tractor tug to enter service for the Moran Towing Corporation.
The existing shafting, struts, propellers, rudders and steering gears were removed. Originally the tug was twin screw. Powered by two diesel electric engines rated at 3,000 horsepower. Her engines were replaced with two, sixteen cylinder, EMD diesel engines. And the tug was fitted with two Ulstein z drives. For a rated 4,200 horsepower.
The existing pilothouse, and stacks were replaced. With lower twin stacks, and a low profile pilothouse that is located further aft to provide the operator with better visibility in all directions. The lower profile was also better suited for work in the confined spaces associated with naval ship work. The tug was, outfitted with Markey capstans, forward and aft staples, and fendering.
The replacement of the existing propulsion machinery left enough space to install a diesel driven 3,000 Gallon Per Minute fire pump. That was connected to a forward and aft fitted 1.500 Gallon Per Minute water/foam monitor.
Her electrical service is provided by two 36kW generator sets. As well as a third 30kW generator set. The tug's capacities are 48,343 gallons of fuel.
