The THD in the mains voltage is below 5% in all operational states. Shaft generator systems are a valuable technical solution for ship owners who are looking for economical and cleaner electrical power generation during their sea voyage.
Shaft generators on board ships are driven by the main engine to supply power to the mains. The mains have to be supplied with constant voltage and frequency by the shaft generator whilst the speed of the main engine changes, i.e. when the vessel travels at different speeds or if the propeller speed strongly varies in heavy seas.
Permanent magnet shaft generator system will produce electric power for all onboard systems in the most energy- and cost-efficient way. The CO2 carriers will be key to Norway’s Northern Lights carbon capture and storage project, helping accelerate industrial decarbonization.
Numerous designs exist for shaft generator systems, which MAN ES categorises in two subgroups: engine-to-generator and generator-to-grid. The engine-to-generator subgroup is related to the position of the shaft gen- erator and the connection between the engine and the shaft generator system.
There are several benefits of installing a shaft generator on board a vessel. The shaft generator enables production of electric power by the ME that has a low specific fuel consumption. In addition, the lower number of running hours of the gensets reduces maintenance and expenses for spare parts.
RPM stability When selecting a shaft generator, the PTO stability must also be considered when deciding whether the PTO is suitable or not for the engine. The mechanical PTO power relative to the NMCR of the engine is 543 kWm/10,680 kW = 5.1%.
