Schottel has announced that its Rudder EcoPeller azimuth thruster has been ordered for a product tanker which will be built at Taizhou Kouan Shipbuilding in China for a European owner.

The 120m long and 21m wide oil/chemical tanker will feature an electric propulsion system, comprising two Schottel SRE 460 L FP Rudder EcoPellers with integrated electric motors, each with input power of 2,000 kW, and one Schottel STT 170 FP Transverse Thruster. The SRE, with a fixed pitch propeller diameter of 2.70 m, will allow a service speed of 12 knots.

Model tests carried out at the Chinese research institute SSRI confirm the performance of the EcoPeller. When compared to a conventional rudderpropeller with nozzle, it demonstrated a 10% increase in propulsion efficiency at a ship speed of 12 knots throughout testing.

With a design draught of 5.8m and a deadweight of 9.150 dwt, the tanker is optimised for shallow water and river operating conditions. Designed by China-based Bestway Marine Engineering Design, the vessel will mainly carry chemicals in bulk as well as industrial chemicals and clean petroleum products.

EcoPellers are available covering the power range 500kW to 5,000kW and offer high efficiency throughout the load range. This, says Schottel, contributes to the ship’s low fuel consumption and thus reduces operating costs and emissions. In addition, the SREs are said to improve course-keeping stability and consequently reduce steering angle corrections.
