Wärtsilä to Carry Out World’s 1st Hybrid Retrofit for Short Sea Vessel

Hagland Captain

In December 2018, Finnish technology company Wärtsilä inked an agreement with Norwegian shipping company Hagland Shipping AS for a hybrid retrofit installation onboard Hagland Captain, a general cargo vessel. 

As informed, it will be the first project of its kind ever in short sea shipping applications.

The installation of a Wärtsilä battery hybrid propulsion solution is expected to significantly enhance the ship’s environmental performance by reducing its emissions, fuel consumption, and noise.

According to the company, 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.

In addition, the battery capacity will be sufficient to sail in and out of harbor on electric power for approximately 30 minutes, which will effectively reduce noise and pollution levels in the vicinity of the harbor.

The project is in response to a collaborative agreement between Hagland Shipping and NOAH AS, the Norwegian environment and resource company, whereby the shipping of materials to the island of Langøya in Norway is required to be via environmentally sound vessels. Non-profit NGO, Bellona, has also given its input to the project concept.

“We believe our mutual project will have a considerable impact in the market and will further the environmental drive towards sustainable solutions in short sea shipping,” Oivind Wendelboe Aanensen, COO, Hagland Shipping AS, commented.

“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,” Paul Kohle, Director, Sales & Sales Support, Asset Management Services, Wärtsilä Marine, said.

“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,” Kohle added.

The company’s hybrid solutions are based on a ‘first-of-its-kind’ fully integrated hybrid power module which combines engines, an energy storage system using batteries, and power electronics optimized to work together through a newly developed energy management system (EMS).
