Hi Vlad,
It's al relative. Eighty centimeter bore isn't indeed very small, but it is relative to the size of the EEE's.
Indeed the "goog old times" 12K98MC/E was the norm 15 years ago for 6000 to 8000teu ships.
Now the power density of these engines has increased significantly during the years especially to the engines I was referring to of the 70ties and 80ties.
And those (super) long stroke engines, S and G type, have a bigger efficiency then shorter stroke engines (K and L type). And with slower speed engines and larger propellor diameters it now became the norm for large container ships.

Good catch!

I guess this is just "back to normal".

I wouldn't call G80 engines "small", one can not go much larger than that in terms of bore size: "our" usual ULCV engines were 12K98ME-C in "good old times", reduced to 11S90ME-C for the "Oscar" class.
I remember back in the day, when there were people predicting geometric progression in expansion of container vessels, the makers tried to keep up. I've probably mentioned this before, but I've seen some advertisements from MAN B&W, where they offered their largest bore engines as 14K1080ME, while the largest engines in absolute terms were 18K98ME... Yes, eighteen cylinders. :)

Luckily for chief engineers of the world, these never saw the light of day, and general public is still waiting for 35.000TEU container vessels with cruising speed of 30+ knots... But, as Ali G would say, "never say ever..." :)

Nice pic. Unbelievable that these two relative small engines can propel such a big ship at still over 20 knots.
Ok their stroke (G-type) is extra superlong but they only have a diameter of 80cm.
Those "huge" 3rd gen container ships of the early 70ties had sometimes three monster engines.
Those ships are really small compared to these 20000teu ships.
