  • Foss Arctic Class Tugs

    Foss Maritime built three arctic class tugboats at its Rainier Shipyard to serve the oil and gas industries in Alaska. Foss engaged Glosten to execute this new design from concept through detailed production design.

    Tugs Designed with Environmental Focus

    While Foss wants to capitalize on this new opportunity, they also want to maintain their reputation for environmental stewardship. The challenge was to improve operational and environmental performance while reducing routine maintenance. And, ABS D0 Ice Class rules drove complex structural arrangements and piping systems.

    Attention to Detail

    A number of environmental features were incorporated into this new tug class, including a highly-efficient twin-screw propulsion system that will be powered by two low-emission engines. Other features include the elimination of ballast tanks, to prevent the chance of transporting invasive species; holding tanks for black and grey water to permit operations in no discharge zones; energy efficient LED lighting; and hydraulic oil systems compatible with biodegradable oil.

    Arctic Class Construction

    Constructed at the Foss Rainier Shipyard, the Arctic Class tugs are 132 feet in length overall with a breadth of 41 feet. The Michele Foss, christened in the spring of 2015, is able to pull 110 tons through Alaska’s icy waters.
