Transneft says that its Russian Electric Motors (REM) plant has completed acceptance trials of two electric propulsion motor prototypes, designed for the new-generation shallow-draft icebreakers of Project 22740M.
The new 2,000 kW propulsion motor is manufactured according to customized specifications and designed for heavy-duty operation. The motor will ensure the icebreaker’s operation in 1.5-meter-thick ice
The company said the equipment was developed and manufactured as part of the import substitution program in Russia and given the lack of similar products in the market.
Shallow draft icebreaker of Project 22740M is intended for operation in the Baltic, White, Azov and Caspian seas and on inland waterways as well as in other sea basins, to provide icebreaker assistance in winter shipping season. This class icebreakers can escort ship convoys in challenging ice conditions, towing vessels and floating facilities in ice and in ice-free conditions, as well as solving other tasks in port basins and infrastructure. The ships can operate at water temperature between -2 and +30 °C and at air temperature between -40 and +34 °C. The Project 22740M vessels are rated the most powerful icebreakers in Russia with a shallow draft of 3.2 m, propeller horsepower of 6 MW and Icebreaker6 ice class.
The Project 22740M was developed by St.Petersburg branch of Lazurit Central Design Bureau. The icebreaker key particulars: LOA: 78.1 m; Breadth: 16.8 m; Depth: 4.8 m; Draft: 3.2 m; GT: 2,839; Fuel endurance: 15 days; Open-water speed: 14 knots.
