Substantial fuel savings and operational cost reduction from optimised propulsion machinery and reduced Auxiliary Generator operation.
How it Works
– for 4-stroke (medium speed) applications
Solution One focuses on the energy efficient operation of any ship equipped with direct-driven propulsion machinery combined with a Shaft Generator system, also called Power Take Out (PTO) system. This solution enables the operation of propulsion machinery in combinator mode – variable speed and pitch of the propeller – with the Shaft Generator online and generating power for the ship’s electrical network. This means that the propulsion machinery can be operated at optimal duty points at all vessel speeds. Energy efficiency is improved which results in substantially reduced fuel consumption and decreased environmentally harmful emissions. This solution also enables two-stroke Main Engine installations to be realized with fixed pitch propeller so that a Shaft Generator system can be installed.
How it Works
– Direct Drive Permanent Magnet 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.
