It's similar for cars, for example. You have a lot of engine configurations, such as V6, having inherent 1st order imbalance, but in most cases, for example, most 60-degree V6s, you just live with it because hydraulic engine mount and other normal dampening mechanism does the job well. However, for I4 with inherent 2nd order imbalance, usually you would need counter-rotating twin balancer shafts to help cancel the vibration, although the absolute amount of NVH is actually weaker. That's all because of the higher frequency nature of this 2nd order thing.

Like you have no idea what marine diesels are.

Talk about V8s, V10s, V12s, I8s, I12s even I16s.

16 Pielstick PA6 should be a 16 cylinder engine, a V-16, eight cylinders in one bank, another eight in the other.

Tell that to the shipbuilders and ship buyers.

Despite electrical propulsion, despite gas turbines, despite the shilling the makers of such, more and more each year, new ships are built with reciprocating engines.
For surface combatants, I'm not sure about that...

I was just using that as an example to support what I said about the frequency of noises. I may know more about marine diesels than you thought, so please don't put your effort in this direction...

Type 075 is running diesels. So does the Type 901.


Here is how the 16 Pielstick PA6 should look like. You think this is an I4 engine?

See the top right corner. The current engine running the Type 054A should be on the far right of the table with the previous being the third from the right.

Making a call that the ship will have a brand new 100mm gun is very bold, to say the least. He must be confident about this information.

Will this be a new gun standard for the PLAN that might appear in new destroyers?
