Technology group Wärtsilä has signed an agreement with Norwegian shipping company Hagland Shipping AS for a hybrid retrofit installation
The project concerns one of Hagland Shipping’s owned general cargo/forestry vessels, HAGLAND CAPTAIN.
According to Wärtsilä, this will be the first project of its kind in shortsea shipping applications.
Wärtsilä will install battery hybrid propulsion solution to 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 at berth for cargo handling by ship’s gear 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 NOx emissions after the retrofit could be between 80 and 90%, while overall fuel cost savings are expected to be in the range of 5-10%. The battery capacity will be sufficient to sail in and out of harbour on electric power for approximately 30 minutes, which will reduce noise and pollution levels in the vicinity of the harbour.
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.
Wärtsilä adds that valuable input to the project concept has been given by the non-profit environmental NGO, Bellona.
“Wärtsilä has been chosen as a partner due to its significant experience in providing environmentally sound solutions such as hybrid systems,” said Oivind Wendelboe Aanensen, COO, Hagland Shipping AS. “Wärtsilä’s forward-leaning and supportive approach has enabled Hagland and NOAH to arrive at an optimal solution. 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, Wärtsilä Marine, said: “Environmental considerations are increasingly important for fleet owners around the world. The need for the latest smart marine technologies has been apparent for some time already in deepsea shipping, and this project is evidence that the need also exists in shortsea transportation.
"Our 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."
