The Danish Ministry of Transport announced last week that Molslinjen had won the two tenders for the Alslinjen and Samsølinjen. The very next day, contracts were signed for the construction of two new electric ferries with Cemre Shipyard in Turkey.

Alslinjen's ferry is to be put into operation by September 2024, while Samsølinjen's ferry is to have its first trip in January 2025.

Still some work to do, f.ex. to build the upper car-deck.
Any infos about what will be inside ? A restaurant, cafe, bar ?
Where are the battery-packs placed ? Maybe in the big "racks" in the foreground of the picture ?
We will travel EXTRA the way from Germany via Flensburg the road 8 in Denmark with this new ferry Fynshav-Böjden and further to Nyborg-Helsingör - Sweden - instead of motorway via Kolding-Middelfart-Odense when this ferry is in operation - and if the ticket-price will be low - in oct. this year or in june next year.
 
i guess, the batteries will be in the engine-room, like in all newbuild ferries for the norwegian regional transport ferries.

I know that Tycho Brahe and Aurora af Helsingborg do have the batteries "on the roof", this solution is quite unike and was only possible because their past life as railferries gave them a very good stability, which made it unnecessary to rearange the engineroom to fit the batteries.
 
Mhmm - i am not a ship-construction- or electric-expert - but all these new electric double-end-ferries (also in Norway, Sweden etc.) - the both screws / propulsion-systems are always placed under both ends of the ships.
So mainly you need only the (today so small like a big bucket only) electric engine(s) (and converter etc.) and the connections from the batteries to the engine(s) and from the engines to the screws.
If we now think that the batteries will be stronger and smaller every year in future - would it then make sense to place the batteries anywhere down under very deep inside the ship ?
There is no big engine-room anymore needed and also no fuel-tanks.
But if the batteries would be placed where it is easy to change them against new better stronger in the future - it would save a lot of costs.
Just if we think that these new ferries will be in operation 20, 25 or 30 years - but i am 100% sure that no battery will work so long.

So here in this picture (A) the big batteries are placed under the deck - but think 10 years further - i am 100 % sure that in 2034 maybe only 15 or 20% of this big space is needed then for the same battery-power and range.
So if the batteries would be placed today at the sides on both ends of a double-end-ferry they could be much more easy changed later - and maybe then also place for 2 cars (or motorbikes) more onboard.
But with underground-placed-batteries - much more complicated to change it later and then you have big empty unused space there.

Here in this picture (B) the batteries are ON the sides of the car-deck - i would always prefer such an solution now if i would order now any new 100% electric ferries.
Short way for charging at docking and short ways from the batteries to engines, converter, screws etc. .
And a lot of things can be easy checked / repaired / changed without to step down anywhere under the deck.
 
hello

Almost all norwegian electric ferries are hybrids with a full size power-plant under the cargo-deck. On ferries, it does not really madder, to carry the extra weight of these diesel engines, further more, for stability reasons it is even an advantage. The space can’t be used for passenger or crew facilities anyway on new buildings.
