- This is from a ship with four Wärtsilä 12V46 V12 (18860KW each) setup with two Marelli shaft generators of 2875 KVA each.
Two and two engines are connected together through a massive gearbox to power two propeller shafts.
They also have the possibility to disconnect each of the engines, so that one engine alone can power the propellershaft and the shaftgenerator. This was the case when making this video.
Yes I know there is flicker in the video. Tried to eliminate this by filming in 100 Fps. But there still was some. Engine room completely light up with LED lamps, and this causes the flickering.
Scotty, Geordi, Trip or Miles wouldn't look out of place in there!
Very good video😊
I came for the Four Wärtsilä 12V46 V12 setup with shaft generators and a massive gearbox and that’s what I got.
Those red hatches on engine blocks are where they shovel the coke.
Thank you for the amazing insights.
Which kind of vessel is this of?
It could be a cruise ship but as far as I'm aware they nowadays usually use diesel-electric propulsion with azipods, no mechanical shafts anymore.
So I guess it is more likely to be some kind of special freighter?
Hi. Yes this is a Ro Ro / passenger ferry. They often install a setup like this to keep the height of the engineroom low. But it is still a ferry, and not a cruise ship, so vibrations are not a big issue.

I see. So now I also understand the (as far as I can evaluate it) comparably large amount of installed generator power.
For a pure freighter you probably wouldn't need that much, but for passenger/ "hotel" service it is necessary.
Was the whole ship made in Italy? For example at Fincantieri?
Italian generators and also Italian-built engines. Could be a coincidence of course.
@@Unimog1600wartsilla is a company in Finland I believe
@@georgeswindoll9138
It is, but as most bigger companies they also have plants in other countries.
And I saw the Italian plant as a reference on the typeplate.
Look for example at 5:52.
Wartsila è anche in Italia a Trieste.@@georgeswindoll9138
Very nice! Love the nameplates, more and clearer pictures would be nice... perhaps better lighting... but in all great content. Subbed!
what's the major electricity consumer on a ferry like this? 2875 KVA is a giant amount of power (i'm assuming things are sized so that one generator can accommodate the whole load)
@@ericgarner2559 Hi. These ships sometimes carry many trailers with cooling generators. These require alot of power when run on electricity. I doubt one generator is enough to power the entire ship, but those two shaft generators together should do the job. So no auxilary generators need to be run when the ship is sailing.
Which Vessel is it?
This video is a fake.
@@brandonsocia2617 Nope. What do you think is fake about it?
@@andresteinumFools only talk. Forget him.
