6 FAQs about [Container ship shaft generator]
What is a shaft generator on a ship?
The shaft generator on a ship is an excellent example of a waste heat recovery system, which not only utilizes the waste energy from the engine but also supplies the additional work to the propeller shaft when the main engine is underperforming. The shaft generator has two modes of operation:
How is shaft generator power determined for container ships?
Based on the collected technical and operational data for container ships of various load capacity, constructed between 2000 and 2015, and by applying different analytical and statistical methods the parameters have been determined. Shaft generators’ power has been established in relation to the power of main engines.
How does a ship generator work?
Every shaft generator comprises of two bearing alternators that are connected to the ship’s main engine to generate electric power. There is also a gearbox, a cooling system, a coupling device that connects the shafts to the ship’s engines, a frequency converter, and a control system.
What are the effects of a shaft generator on a ship?
These effects however include certain defects. The main ones are: using a shaft generator to reduce the ship speed as a part of the main engine power is transferred to the generator as opposed to the propeller. The speed decrease depends on the shaft generator power and is within the range from 5% to 10% of the operational speed (Balcerski 1998,
Why do shipbuilders use shaft generators as power take-off systems?
Shipbuilders are now integrating shaft generators into their newbuilds as Power Take-Off (PTO) systems to achieve considerable savings on energy and meet the necessary fuel/energy regulations. To ensure fuel sustainability and efficacy, some new vessels have incorporated hybrid propulsion systems into their vessels.
Should you install a shaft generator on a vessel?
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.
