Is that something like a load bank/generator combo? I’ve been around generator repair facilities where a generator is hooked up to a load bank where various loads can be applied to check out the generator. Max loads really make the big diesel engine bark, and usually goes to wide open throttle.

I work in an electric motor repair facility and we recently hired someone who worked for a railroad. He told me about the generator test but those are built into the locomotive. They do have some sort of a load bank which I'd love to see in action. We load electric motors hydraulically but we are limited to 500 hp and that generated enormous heat right away. I've been studying this particular diesel for quite a while. Given the known efficiency of diesels and the energy content of the fuel oil, they can get a rough idea of HP simply from fuel burn.

All fascinating stuff that's for sure! I read that this Korean diesel is some 50 percent, I think, more efficient than the gas turbines that are also used.

We have a nuke power plant nearby. About 8 of these diesel engines would equal that nuke.

We test 4,000 hp pumps and the problem of heat dissipation is always a problem in testing large “stuff”. We worked on a design for a test loop for some other equipment using cooling ponds with labyrinth channels to make the distance back to the cooling suction longer.

Building test stands, loops and such correctly is sometimes as big a challenge as the article being tested.

“We load electric motors hydraulically - - - “

This is way off topic, but I have an old tractor that has no brakes, when going down a steep incline I bottom out a cylinder control valve, which causes the hydraulic pump to work at max pressure, thereby putting a good size load on the engine.

In essence, it’s an engine brake that slows the whole tractor down. I’ve been doing this to that same tractor for over 20 years. Nothing seems to get harmed.

Just about everything about one of the monsters!
Except the fuel line size?

Fig 7 shows it, it is pipe in pipe, my guess is outer 12 inch IPS, inner 8 inch IPS?

8 inch @ 300 bar! that is some fuel line???

Thank You thackney!
