Wärtsilä has signed an agreement with international shipping company Hagland Shipping AS for a hybrid retrofit installation.

The project will take place onboard the Hagland Captain, a general cargo vessel owned by Hagland Shipping. It will be the first project of its kind ever in short-sea shipping applications. The agreement was signed in December 2018.

The installation of a Wärtsilä battery hybrid propulsion solution will significantly enhance the ship’s environmental performance by reducing its emissions, fuel consumption, and noise. Included in the solution are a shore power connection to provide 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 estimated that the total reduction in nitrogen oxide (NOx) emissions after the retrofit could be as much as 80 to 90 percent, while overall fuel cost savings are expected to be in the range of 5 to 10 percent. The battery capacity will be sufficient to sail in and out of harbour on electric power for approximately 30 minutes, which will effectively reduce noise and pollution levels in the vicinity of the harbour.

“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. Wärtsilä is responding to these developments with its Smart Marine Ecosystem approach, which through the use of high levels of digitalisation and connectivity, is creating greater efficiencies, increased safety, and more sustainable solutions,” says Paul Kohle, Director, Sales & Sales Support, Asset Management Services, Wärtsilä Marine.

Wärtsilä’s hybrid solutions are based on a ‘first-of-its-kind’ fully integrated hybrid power module. This combines engines, an energy storage system using batteries, and power electronics optimised to work together through a newly developed energy management system (EMS). It marks a new frontier in marine hybrid propulsion.
