I came across this (by way of a diversion) whilst looking at an article about Bin Sulayem, as you're into engineering you're probably aware of it, but who knows. Anyway, google " Wartsila-Sulzer RTA96-C "

look here. http://people.bath.ac.uk/ccsshb/12cyl/

An engine with a bore of 38" and a stroke of 98", in which the crankshaft alone wighs 300 tons and the engine is 89 feet long, some really good photo's, including one showing steps built into the crankcase for people to gain access to the crackcase.

WOW! thanks!

Give me a little time to get my head around this, I've just got in from the garage where I've been rebuilding the head of my 1.4L K series 4 pot for my Phaeton. Not quite in the same league!

Lol !! you're welcome, I thought it was pretty awe inspiring, good luck with the Dutton, these days most of the younger generation think a decoke is some sort of drug detoxification programme

I was curious, stigga, and had a look.  It's stupendous!  What a piece of machinery, how on earth did they build it.  Some of the parts would have to be cast wouldn't they?  Abolutely amazing !!!  I've attempted to add a picture, hope it works.

 

The cylinder deck (10 cylinder version).  Cylinder liners are die-cast ductile cast iron.  Look at the size of those head studs!:

 

Holy-ship!!!

Its an awesome piece of kit isn't it, the figures are almost mind boggling  I think there's a video of it in action on youtube

That's boring.

That's boring.

That's funny.

Thanks again stigga, that really is something else. I've done a bit more reasearch and found where it's used, the Emma Maersk container carrier seems to be the biggest ship to have one of these.

Can you imagine what the foundry must be like that those engines were cast in? It must be collossal! What about having enough molten metal to be able to pour for one casting, how ever do they manage that? The manufacturing problems must be immense, truly awesome.

A crankshaft that weighs 300 tons and it was all I could do to lift the crank out of the Jaguar XK engine I overhauled a couple of years ago! The machinery they must have for lifting must be something special as well!

 

Just a thought, does anyone know how you start one of these things? I know about electric start and compressed air starters but this is a bit different. Does it have some form of donkey engine? Any ideas? I've had a quick look on the web and couldnt see anything.

I would have assumed a slave engine given the size of the flywheel, apparently this is the starter for a Wartsila, though it's not mentioned which specific engine its for.

Great!!!!!

 

    

 

That's a brilliant picture of the ship, guthrum, and I see you've spotted the secret starting system  lol

The RT‑flex96C and RTA96C engines are uniflow scavenged with air inlet ports in the lower part of the cylinder and a single, central exhaust valve in the cylinder cover. Scavenge air is delivered by a constant-pressure turbocharging system with one or more high-efficiency exhaust gas turbochargers depending on the numbers of cylinders. For starting and during slow-running, the scavenge air delivery is augmented by electrically-driven auxiliary blowers.
