FULL SCALE EVALUATION OF THE AIR BUBBLER SYSTEM ON THE GREAT LAKES ICEBREAKER USCGC "KATMAI BAY"

This paper presents the results of the tests conducted on the U.S. coast Guard's 42.6 m Great Lakes icebreaker Katmai Bay. The Katmai Bay is the first of a class of icebreaking tugs specifically designed for icebreaking on lakes and rivers. It displaces 700 tons and has a single propeller driven by a 2500 hp dc-motor. It has an air bubbler system and low friction bottom coating of Inertia 160, to reduce the coefficient of friction between the ice and the ship's hull. Results indicate that the bubbler system decreases the required power by about 30%. Order from NSFI as No. 22408.
