Another advantage is the redundancy that can be achieved with the gearbox with regard to propulsion. On Hannibal, four common-rail diesel engines gener- ating a total output of 57,600 kW pro- vide the primary drive. Each pair of en-gines transmits the required power to the relevant propulsion drive with adjustable propellers via a type GVLQ 2500 gear- box. Because of the combined power of the two diesel engines each of the two gearboxes thus transmits an output of 2 x 14,400 kW. Multi-Engine SolutionA concept of this kind with four engines and two propellers offers passenger ships a good combination of safety and comfort. On one hand, single- or twin-engine drive enables different speeds to be run on the propulsion drive. In the case of the Hannibal, these are speeds of 514 rpm or 139.9 1/min. On the other, a multi-engine solution of this kind of-fers especially high servicing ß exibility. After all, an ocean giant cannot just be parked on the open sea.With a breadth of 7.35 m, a height of 4.92 m and a length of 3.7 m these units weigh 89 tons and are thus the largest ship gearboxes ever built at Siemens?s Voerde/Friedrichsfeld location. Even transport to the shipyard in South Korea was a masterpiece of logistics.Photo
