THE GEARED DIESEL ICEBREAKER MUDYUG
A description is given of the icebreaker Mudyug which is the first of a series of three icebreakers ordered by the Soviet Union from the Wartsila shipyard, Helsinki <Finland>. Principal particulars: Length, o.a. 92.0m, w.l. 78.5m; Breadth, max. 21.4m; Depth 10.5m; Draught 6.5m; Displacement 6138 tonnes; Max. delivered power 9100kW; Bollard pull at 7000 kW 917 kN; Trial speed 17.45 knots. In contrast with Soviet icebreakers of this propulsive power, which usually have Diesel-electric propulsion, the Mudyug is provided with a geared Diesel installation comprising four Wartsila-Wasa engines, each rated at 2390 kW, 760 rpm. They drive two controllable-pitch propellers through single-stage reduction gearing. Each propulsion shaft includes a 11.5-tonne flywheel to assist propeller rotation under ice-impact conditions. The ship's progress in ice is also assisted by an air lubrication system for the hull. Two semi-balanced rudders are fitted, each actuated by independent steering machinery.
