Consumption of a yacht !! 200000 liters / 15 days

[jean63]

Who says better: Ferry-boat crossing Marseille-Ajaccio (say Corsica): the biggest = "Napoleon-Bonaparte".

I will look for the characteristics of this boat which transports 1000 people and 800 cars (to be checked), which I will put here (I take it every year once round trip)

If André or someone else is competent in the matter, with the power of the engines and the size of the ship, we can perhaps imagine the consumption per hour.

I always thought about that when I watched the "chimneys" spit out their black smoke "how much can such a device consume?".

And then, since there is no more snow in the mountains, we use ultra-energy-efficient snow cannons, .... therefore warming, therefore less snow, therefore .....
It's a bit like fighting the heat wave with air conditioning.

Be careful with this kind of comparison ... because you must not forget to relate consumption to the tonnage transported ... For info the most economical means of transport is maritime transport ...It consumes the least energy per km.tonne (i.e. to make a tonne 1 km). The bigger the boat, the better its performance ...

Uh ... are we that bad?
Vincent27 even works in maritime construction so yes I think there will be competent people here ...

It spits out black because some still work with heavy fuel oil (very viscous fuel oil ... and almost black with crude oil what ...) once the heaters are hot it's a little less worse ...

[Christophe]

And then, like ...

Well, I hadn't seen you, it's a good thing that you're here, you will no doubt be able to answer Jean more precisely than I do on the cons. Maritime ...

For Jean, look at the message he wrote on the Sulzer here: https://www.econologie.com/forums/micro-coge ... 98-30.html



These are the most efficient engines in the world ... (if so ...)

[jean63]

Christophe : I agree with you ... and so much the better: in this case I will feel less guilty about going to Corsica by ferry, but hey it's for holidays so not really USEFUL.

Be careful with this kind of comparison ... because you must not forget to relate consumption to the tonnage transported ... For info the most economical means of transport is maritime transport ... It is the one that spends the least energy per km.tonne (i.e. to make a tonne do 1 km). The bigger the boat, the better its performance ...

Okay, I'm going to the SNCM website to get the characteristics of the ferry.

OK seen, vincent27 will be able to give us the answer!

The SNCM fleet:

Technical specifications

Napoleon Bonaparte (1769 - 1821)
First Consul then Emperor of the French under the name of Napoleon 1st. 8th vessel bearing this name.

Commissioning: April 1996
Length: 172 m
Beam: 30,40 m
Draft: 6,60 m
Operating speed: 23,8 knots
Power: 43 kW
Passenger capacity: 2 people
Garage capacity (3 levels): 708 cars
Anti-roll stabilizer

ouh, I got stuck on the number of people transported (1000 ald 2500!); it's perfect, it optimizes the amount of fuel oil consumed per person per car transported.

Now vincent27, it's your turn to play .......

Thank you.

21 years, but I do not make them ...

It reminds me of some memories: in fact at your age I was in the army (yes 12 month in my time !!) in Trier in Germany in heavy artillery, I was radio Morse (after a training period of 2 intensive months); It has disappeared recently (the walrus). We had a good time with that.

I had a computer IUT after the bac C (S now) then a year of work before leaving to the army .... here it is, it is very far away all that. And you ?

I am finishing my studies at the engineering school in Geneva. In December 2007 I finished and in March 2008 I left for the army, still compulsory with us.


After that, I'm not sure yet what I'm going to do. We'll see.

Little indiscreet question, it was in what year you were 21 ...

These are questions that do not arise!

[jean63]

Little indiscreet question, it was in what year you were 21 ...

well in 1971, because born in 1950!

PS: for the pros of boat engine consumption calculation, I gave the characteristics of the Napoleon Bonaparte ferry (SNCM) in the post above. It would be interesting to also calculate for an NGV and see the difference in consumption reported to a passenger.

Thank you.

I have absolutely no doubt that shipping is performing well. But it would not rather be on the large freighters that are dragging and not really valid for the Nice-Ajaccio in 3 hours.

I am wrong??

[jean63]

The big freighters that drag, it does not bother me, I cross at night and I sleep, but for me it is shorter to go to Marseille (from Clermont-Ferrand I need 5 hours max - 450 kms).

To go to Nice, I have to take the paying motorway, it doesn't suit me (if you knew with which car I go there ...). I have an interest in driving as little as possible !!! and in addition I stay on the Gulf of Ajaccio.
