First hybrid retrofit for short-sea operator

HELSINKI: February 2019. Wärtsilä has signed an agreement with Haugesund, Norway-based Hagland Shipping for the first-ever retrofit of a Wärtsilä battery hybrid propulsion unit in a general cargo vessel owned by the short-sea operator.

Wärtsilä’s hybrid solutions are based on an unique fully-integrated hybrid power module that combines engines, an energy storage system using batteries, and power electronics optimised to work together through a newly-developed energy management system.

The NOK 30 million installation in the Hagland Captain breakbulk carrier, which includes a shore connection to provide power for loading/unloading and for battery charging; a new reduction gear with power take-off and power take-in technology; and a Wärtsilä NOx Reducer; is expected to significantly reduce the ship’s emissions, fuel consumption, and noise.

Wärtsilä estimates an 80 to 90 percent reduction in nitrogen oxide (NOx) emissions while overall fuel cost savings could be as high as 10 percent. The battery capacity would be enough to sail in and out of harbour on electric power for approximately 30 minutes.

The retrofit is the result of an agreement between Hagland Shipping and NOAH AS, the Norwegian environment and resource company, to provide services to the Norwegian island of Langøya via “environmentally sound” vessels.

“Wärtsilä has been chosen as a partner due to their significant experience in providing hybrid systems,” said Hagland Shipping COO Oivind Wendelboe Aanensen. “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.”

Paul Kohle, director Sales & Sales Support, Asset Management Services for Wärtsilä Marine added: “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.”
