The Saint Lawrence Seaway Development Corporation awards construction of Glosten-designed harbor tug to Washburn & Doughty

MASSENA, NY, January 10, 2020 /24-7PressRelease/ — The Saint Lawrence Seaway Development Corporation (SLSDC) announced that it has awarded the construction of its new ASD (Z-drive) harbor tug to Washburn & Doughty Associates, Inc. of East Boothbay, Maine. The HT-60, the smallest in the Harbor Tug series developed by Glosten, a US based naval architecture firm, is slated for delivery in 2021.

“This new vessel will be used to carry out a variety of construction and maintenance duties for the US portion of the St. Lawrence Seaway, including routine maintenance of lock gates, maintenance and positioning of aids to navigation, ice management, and removal of accumulated ice from lock walls,” said Craig Middlebrook, Deputy Administrator of the SLSDC.

The Glosten HT-60 is designed to capitalize on the operating advantages afforded by a broad bow form with a semi-raised foc’sle deck and full visibility and winch controls from a single operating station in the pilothouse. To perform its intended work functions in ice, the hull has been ice-strengthened to ABS Ice Class C0 standards. The Z-drive units are powered by a pair of EPA Tier 3 diesel engines turning carbon fiber shafts for a combined 1,320 BHP at 1,800 RPM. At 60′ overall, the tug is right-sized for maneuvering inside lock chambers, with a wide 28′ beam to improve performance in ice and enhance stability for deck crane operations.

“Washburn & Doughty is proud to be selected by SLSDC to build its new Z-drive tug. We look forward to working with both SLSDC and Glosten on this exciting design,” states Katie Doughty Maddox, President of Washburn & Doughty.
