Shaft Generator as a motor for boosting the Main Engine
in demanding conditions or low load optimised Main Engine.
Substantial fuel savings and reduced capital expenditure, ice-boost and low load optimisation of the Main Engine.
– for 4-stroke (medium speed) applications
Solution Three provides auxiliary power to boost the Main Engine when the application finds itself in demanding situations, such as high bollard pull or sailing in icy condition. This solution can also be used for economical slow steaming with the single Main Engine in a twin-shaft installation. With the Boost Mode solution taken into account during the ship’s design phase, the total operation cost of a vessel can be much reduced compared with traditional propulsion machinery design. This is because the Main Engine size can be optimised to the propulsion power needed under normal conditions. Additional power boost is taken from the Auxiliary Generators as required. This solution enables Boost Mode for any vessel type by running the WE Drive™ in Power Take In (PTI) mode. Solution Three also offers the functionality as outlined in Solution One.
– Direct Drive Permanent Shaft Generator for 2-stroke (slow speed) applications
The permanent magnet rotor is mounted on the intermediate shaft of the propulsion system. Mass and inertia are very low and thus the impact on propulsion system torsional vibration calculations (TVC) remains minimal. No additional bearings are required, thus the propeller shaft system design remains uncompromised. The generator housing, consisting of a compact, feet mounted stator package, including the rotor and intermediate shaft, is positioned on the generator bed in the propeller shaft line and connected via flanges.
