Pity its not applied all around the world to everyone.

AT 2:17 it should say "a bore of 960mm and a stroke of 2500mm".

Was about to say the same. Many years ago was Engineer officer on container vessel, that had 10cly 900mm bore 1590mm stroke. That was way back in 1976, even then used about 100tonnes of fuel per day at full speed. Happy days.

Great video , Educational !!!

I'd like see how these huge parts are cast at foundries...gotta be amazing!

FYI, when I watch a video specifically about ship engines, I want to see engines, not cargo ships driving around......

Awesome as always! ❤️

You got the stroke and bore backwards at 2:17, the bore is 960 mm and the stroke is 2,500 mm.

As a diesel mechanic this extremely fascinating, Ty!

The biggest IC engine is Wartsila RT-flex 96C developing 108 920 BHP, 14 pistons, 96cm diameter, 5700kW each

Authorized speed through a port ==>> 3 Knots.

I believe you'll find he mentioned the wide bore and short stroke at the beginning of the video. In the automobile world this is referred to as an 'over-square engine. All high performance engines are built is way. Referring to marine diesels, common sense tells me that with the huge reciprocating mass of the pistons and connecting rods a similar design is essential to reduce bearing stresses and external dimensions of the complete power-plant.

Tells us everything without being specific about anything.

The engineering looks intense...how the phuck do they do what they do?

The trouble with this damn life is that everything costs, from a simple pencil to another thing costs, and if I don´t have money, what can I do??

If talking about turbine engines on navy vessels, it would be nice to see turbine powered vessels, instead of nuclear-powered aircraft carriers or mechanics working on Diesel engines. Just saying.........

You mixed up bore & stroke diameters.

What the hell has that to do with the video - or are you yet another example of the hideously inane results of American dehumanising of recruits?

Are the engines built inside ore outside the ships? If outside as I see in Korea how they put it inside? Thank you beautiful.

Look at all those crankshafts and connecting rods. You can see multiple machining passes on them because their machine was only big enough to do a partial plane. So some of the flat surfaces you can see 3 or 4 passes across just to make them into 1 single flat cut. With boats getting bigger all the time, and already the machines aren't big enough to make parts in 1 cut, it looks like there would be room for a company that could make big enough machines to make these parts better. They really look very crude if you compare them to high quality engine parts for cars. It's easier to make them nice on a small size. It looks like there's tons of room for improvement. They clearly aren't forged either, just milled to final shape. If they were forged and WPC and cryo treated, they could easily make those parts half the weight and they would be much stronger and way longer lasting and more efficient. But it would take an enormous facility to be able to do that and it would cost billions to make. But it would pay for itself after not too many years if ships keep staying huge and getting bigger.

I wonder what mpg those massive ships get

Not sure about commercial ships but an aircraft carrier gets about 3ft. per gallon.

Depends greatly on ship/engine size. A modern slow speed diesel engine today on an "average" sized ship is usually a 6 cylinder engine, about 500mm bore, and turns out about 15k horsepower at 110ish RPM. These engines burn about 30 tons per day. Larger engines with more cylinders burn more. Anywhere between 90-150+ tons per day.

General Electric gasturbines are far more efficient., smaller and vibration free 420 000 kw beats this old diesel system at the only cost of a reduction gear. Compare it with this monstrosity of ony 80000 kw There is great disconnect here, given the need of using all available volume for cargo. Comments anyone?
