Here are some examples of marine electric applications:

Electric propulsion systems have excellent dynamic characteristics, allowing for smoother manoeuvring and positioning.

Changes in propeller speed and propeller reversals during manoeuvring can be carried out at optimum acceleration rates, making navigation more efficient.

The electric propulsion system's ability to quickly adjust propeller speed and direction makes it ideal for navigating through tight spaces or changing course quickly.

This is especially useful in situations where precision and control are crucial, such as docking or navigating through congested waterways.

The electric propulsion system's smooth operation also reduces wear and tear on the vessel, extending its lifespan and reducing maintenance costs.

Merchant vessels such as feeders, RoRos, short-sea PCTCs (pure car and truck carriers), and small tankers will gain significant benefits from an electric propulsion system.

These vessels often operate at varying speeds and have a high hotel load, making electric propulsion the ideal choice. Electric propulsion systems offer numerous advantages, including low noise and vibration-free operation.

One of the key benefits of marine electric power and propulsion is its simplicity and flexibility. This is because it allows for the combination of power for propulsion and on-board equipment in a single connected system.

Here are some of the key features and advantages of marine electric power and propulsion:

Converter topologies play a crucial role in electric marine propulsion systems. There are three basic topologies to consider: AC, DC, and Wärtsilä's patented Low Loss Solution.

AC systems are the most common diesel-electric propulsion solution, available in Low Voltage (440 / 690V) or Medium Voltage (6.6 / 11 kV) settings. These systems combine a switchboard with transformers and AFE or DFE converters for each propulsor.

A DC system is gaining popularity, always in Low Voltage (1000V) setting. It has the advantage of connecting variable speed gensets and batteries, which are always DC.

Wärtsilä's patented Low Loss Solution reduces the number of transformers needed and electric losses, while increasing the redundancy of the propulsion system. With over 200 installations, it's the market standard for DP/offshore vessels.
