MAN commissions Siemens gearbox for fishing vessel
The Flender two-speed gearbox will enable the vessel to use the speed modes to generate on-board power while the diesel engine is operational.
The generator used for producing electrical energy can also function as a propulsion motor, drawing power from additional generators in the event of a main propulsion failure. In this operating mode, the gearbox would transfer an output of 1,700kW to the adjusting propeller, resulting in an output speed of around 117rpm.
The gearbox comes with a rugged housing and a compact design in which the oil supply system is completely mounted on the gearbox. To guarantee hydraulic adjustment of the propeller, the output shaft has been drilled hollow to accommodate the oil pipe.
Stefan Tenbrock, CEO of the mechanical drives business unit at Siemens, said: “Since 2002, we have been building two-speed gearboxes based on the established Flender gearbox for marine applications. Our experience and expertise fathered over many different applications involving ever new challenges and close cooperation with our customers enable us to engineer high-quality individual solutions.”
