Propulsion is by means of two
Fairbanks Morse diesel engines with Westinghouse DC generators and
one Westinghouse DC motor. This diesel-electric set-up can power the
ship through fresh water ice up to 20 inches thick and break ice up
to 3 feet thick by means of ramming. It can also ram thru pressure
ridges of up to eight feet in thickness. WTGBs use a low
pressure air hull lubrication or bubbler system that forces air and
water between the hull and ice. This system improves ice-breaking
capabilities by reducing resistance against the hull thereby decreasing horsepower requirements.
