Built in 2012, by Washburn and Doughty of East Boothbay, Maine as the Katie T. Moran (hull #103) for the Moran Towing Corporation of New Canaan, Connecticut.
Named for Katie Tregurtha, the daughter of the Moran Towing Corporation's president Ted Tregurtha and his wife Marci. Katie Tregurtha is the granddaughter of Moran chairman, and CEO Paul Tregurtha and his wife Lee.
She was the twenty-second tractor tug built for the Moran Towing Corporation by Washburn and Doughty. And, the thirty-third tractor tug placed in service to the Moran Towing Corporation.
The tug was the second of three nearly identical boats, designed by Jensen Maritime Consultants of Seattle, Washington. Her predecessors, the Capt. Jimmy Moran and the Shiney V. Moran. That were constructed in 2008 and 2009, respectively. By C and G Boatworks Incorporated of Mobile, Alabama.
The Katie T. Moran's, design was modified and upgraded by Washburn and Doughty Associated of East Boothbay Harbor, Maine. The upgrades insured that the piping and electrical systems are consistent with the Moran towing Corporation's larger fleet of tugs and barges. The tug's hull features a deep skeg forward for escort work. However, the skeg remained open at the aft end, to allow for better maneuverability. The skeg also provides for a more stable platform when underway, minimizing rolling due to the seaway. Additionally, large machinery removal hatches were constructed in the main deck, and deck house to allow for easy removal of equipment from the engine room.
Powered by two, sixteen cylinder, MTU-DD 16V4000M61 diesel engines. With Lufkin MV1600VS reduction gears, at a ratio of 2:1. Driving two, Schottel 1215 "z-drives," for a rated 5,000 horsepower.
Her electrical service is provided by two 99kW Marathon 363PSL1607 generator sets. The tug's capacities are 34,606 gallons of fuel, 1,717 gallons of lube oil, 3,170 of fresh water, and 9,378 gallons of ballast water.
Her deck equipment consists of an escort hawser winch mounted on the bow, and an "h" bitt. With a hydraulic capstan outfitted on the stern for towing operations and line handling.
