NORWEGIAN ELECTRIC SYSTEMS STRENGTHENS ITS POSITION

NORWEGIAN ELECTRIC SYSTEMS STRENGTHENS

Norwegian Electric Systems strengthens its position as world leading system integrator for zero emission ferries. In addition to many delivered ferries the last years, Norwegian Electric Systems (NES) has recently completed the delivery of 5 zero emission propulsion systems to Fjord1 ferries outfitted at Havyard Ship Technology shipyard in Sogn, Norway.

 These ferries have a capacity of 50 cars and will operate fully electric at four different ferry-crossings along the western coast of Norway. Crossing time for the ferries differs from 13 to 30 minutes depending on which ferry route they are operating in.

“With these ferries, NES has now a total of 19 fully electric or hybrid electric ferries operating in Norway”, says Jan Kåre Sundgot, project manager for these 5 projects.

The new buildings with Hull number 141-145, was delivered in record time. 2,5 years from contract signing for all 5 ferries to handover of ferry number 5.

“The success criteria for these projects is the world leading competence and experience we have gained through several similar projects over the last 4 years”, says Jan Kåre and mentions Tor-Harald Njåstad and Kjetil Ripe which both works as project engineers in NES.

“They have both been key persons together with the rest of the technical team through the project”.

The delivery from NES includes complete propulsion package with charging systems, batteries, Quadro Master® DC switchboards, AC switchboards, generators, and automation systems (IAS/PMS).

Zero-emission revolution

During the zero-emission ferry revolution in Norway, NES has developed a DC switchboard called Quadro Master®. The Quadro Master® is a modular DC system that is based on proven technology which has shown to be reliable and efficient. The Quadro Master® can also be used on other vessels where DC voltage would be applicable.

The system integrator plays a critical role in the transition from conventional propulsion systems towards new greener solutions. Our competence on each product combined with system understanding results in safe and optimal operation of the ferries.

NES is also responsible for the onshore charging systems for these ferries.

The ferries need to charge the batteries at both sides of the crossing, which means a total of 8 shore charging stations.

The vessels which is now delivered, has its similarities, but also have some unique customizations with regards to power and energy consumption.

Hull number 141 “Fedjebjørn” which operates between Fedje and Sævrøy need more energy for one crossing than the grid company can deliver. By installing batteries on shore, we can boost the charging power and also help stabilizing the grid.

NES is constantly monitoring and controlling that the grid is not overloaded and making sure that our charging systems operates according to agreements with the grid owner.

Hull number 142 “Bømlafjord” will operate between Langevåg and Buavåg in Bømlo, while hull number 145 “Stangvikfjord” will operate between Kvanne and Rykkjem. The last two ferries, “Smøla” and “Møringen” will operate between Edøya and Sandvika.
