World’s first hybrid retrofit for short-sea shipping vessel underway
Technology group Wärtsilä Corporation on Friday (8 February) said it has entered an agreement with the international shipping company Hagland Shipping AS during December 2018 for a hybrid retrofit installation onboard the general cargo vessel Hagland Captain.
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, says Wärtsilä.
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%, while overall fuel cost savings are expected to be in the range of 5 to 10%.
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.
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 has been chosen as a partner due to their significant experience in providing environmentally sound solutions such as hybrid systems,” says 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.”
