Bergen-based systems integrator Norwegian Electric Systems (NES) has completed the delivery of five zero-emissions propulsion systems to Fjord1 ferries, outfitted at Havyard Ship Technology’s shipyard in Sogn, Norway
The ferries have capacity for 50 cars and will operate fully electric at four different ferry-crossings along the western coast of Norway. Crossing times for the ferries vary between 13 and 30 minutes depending on the route.
In addition to the propulsion packages, NES is also responsible for the onshore charging systems for the ferries. The ferries need to charge their batteries at each side of a crossing, requiring eight shore charging stations. In terms of charging, NES said the delivered vessels share similarities, but have some unique customisations with regards to power and energy consumption.
The vessel Fedjebjørn, which operates between Fedje and Sævrøy, requires more energy for one crossing than the grid company can deliver, for instance. By installing batteries on shore, the company hopes to boost charging power and help to stabilise the grid. The company said it is “constantly monitoring the grid to ensure it is not overloaded and making sure that our charging systems operates according to agreements with the grid owner”.
Bømlafjord will operate between Langevåg and Buavåg in Bømlo. Stangvikfjord will operate between Kvanne and Rykkjem and Smøla and Møringen will operate between Edøya and Sandvika.
For the five vessels, NES delivered a propulsion package consisting of charging systems, batteries, AC switchboards, generators, automation systems and its proprietary DC switchboard, Quadro Master. The company said this modular DC system can also be used on other vessels where DC voltage would be applicable.
NES project manager Jan Kåre Sundgot said “With these ferries, NES now has 19 fully electric or hybrid electric ferries operating in Norway”.
