The installation of the battery hybrid propulsion solution will improve the ship’s environmental performance by reducing its emissions, fuel consumption, and noise. Included in the solution are a shore power connection to supply power for loading/unloading operations and for battery charging, a new reduction gear with power take-off (PTO) and power take-in (PTI) technology, and a Wärtsilä NOx Reducer (NOR).

It is expected that the total decrease in nitrogen oxide (NOx) emissions after the retrofit could be as much as 80 to 90%. In the same time, the overall fuel cost savings are expected to be between 5 to 10%. The battery capacity will be enough to sail in and out of harbour on electric power for about 30 minutes, which will reduce noise and pollution levels near the harbour.

Paul Kohle, Director, Sales & Sales Support, Asset Management Services, Wärtsilä Marine, said:

Environmental considerations are increasingly important for fleet owners around the world. The need for the latest smart marine technologies has been seen for some time already in deep sea shipping, and this project is evidence that the need also exists in short-sea transportation

These hybrid solutions combine engines, an energy storage system using batteries, and power electronics, which aspire to create a newly developed energy management system (EMS).
