Two newbuild azimuth stern drive tugs with low-emissions technology have been officially named at a port in New Jersey
Moran Towing has named two of its newbuild low-emissions azimuth stern drive (ASD) tugs at Red Hook Terminals in Port Newark, New Jersey.
The Connecticut-headquartered owner took delivery of Newt Moran and Thomas C Moran in Q3 2025 after their construction by Master Boat Builders in Coden, Alabama as part of its fleet investment strategy.
These 28-m tugs were built to Robert Allan Ltd’s RApport 2800 design with more than 80 tonnes of bollard pull. They have a beam of 12 m and 5,050 kW of installed propulsion power coming from two high-speed diesel engines driving twin Z drives.
Each Caterpillar-manufactured 3516E engine on these tugs is linked to a selective catalytic reduction (SCR) unit to reduce NOx emissions for US Environmental Protection Agency (EPA) Tier 4 compliance and to attain the ABS notation LEV for low-emissions vessel.
Red Hook Terminals handles ships transporting bulk commodities such as stone aggregates and lumber, and containers, including refrigerated units for transporting frozen and perishable products.
Since 2021, Moran has added 10 ASD tugs, increasing its fleet to more than 76 ship-assist vessels including 56 ASD tractor tugs, making it one of the largest harbour-based fleets in North America.
This included 395-gt, 28-m tugboat William E Moran, also built by Master Boat Builders and delivered in Q2 2025 to support ships in the Port of New York.
In 2024, Moran welcomed Paul T Moran and George James Moran after their construction by Washburn & Doughty Associates in East Boothbay, Maine, to a design by Crowley Engineering Services with 60 tonnes of bollard pull.
According to AIS, Paul T Moran is operating in Norfolk, Virginia, and George James Moran is in Baltimore, Maryland. These 26-m tugs have a beam of 11 m and 3,800 kW of power.
In Q4 2024, Mary Jane Moran entered service in Port Arthur, Texas, and Patricia B Moran started in Norfolk after their construction by Master Boat Builders with an overall length of 26 m, a beam of 11 m, a bollard pull of 60 tonnes and 3,800 kW of power. These tugs have twin Caterpillar 3512E engines linked to an SCR for EPA Tier 4 compliance, driving two Kongsberg US 205 Z-drives for speeds of up to 12 knots.
