German propulsion manufacturer, Schottel, has been awarded a contract to provide azimuth thrusters for a large Chinese river cruise vessel.
Owned by Changjiang Cruise Overseas Travel and built by China Merchants Heavy Industry (Jiangsu), the new ship will be equipped with three Schotteltwin propeller systems.
The CSC designed vessel is intended for operation on the Yangtze River, China’s largest river.
She will be powered by electric motors driving three twin propeller units type STP 310 with an input power of 1,000 kW each and a propeller diameter of 2 m. The 150 m long and 23 m wide vessel will have an operating cruise speed of 14 knots and will accommodate 600 guests served by 150 international crew members.
The new vessel is scheduled to enter into service in September, 2021.
Schottel claimed that its twin propellers are ideal for quiet vessel operations and for those with limited installation space, draught or propeller clearance.
By sharing the load between two propellers rotating in same direction and of the same diameter, the risk of cavitation is minimised and tip clearance is increased. Both of these characteristics, in turn, leads to low noise and vibration levels. This concept also improves the efficiency of the propulsion system and reduces fuel consumption, compared to single propeller systems, the company said.
