Where did you get that it's a localized copy of an 80s era Ukraine turbine? Which Ukrainian turbine was it copying?

Not sure which exact model but this states in pretty clear terms that the original design was Ukrainian
yes, but which engine?
this is all the UGT series. 25000 -> 25 MW
15000 -> 15 MW
60000 -> 60 MW
I don't see a UGT-110000
I think back in late 90s, people from PLA ended up in Ukraine and saw a gas turbine they liked in UGT-25000 and they bought 8 of them. You know why? Zorya only had 8! That's Ukraines gas turbine industry. A lot of brochures and not a lot of actual production
So then, we had 2 052Bs and 2 052Cs built with those 8 engines and then we had like a 5 year delay because they were waiting on domestic GT-25000 to become available. So yeah, it's not easy to have all domestic components to your gas turbines.
We had this news recently that China sold 20 gas turbines to Russia for their arctic project. Why would Russia need Chinese gas turbines when they can produce their own? Well, it's not easy to be able to produce it all domestically

I don't know the specific model, all I'm saying is that state media is on record clearly stating that the design is in some manner Ukrainian. Whether it's one the Ukrainians never built themselves, or a scaled version of a smaller model, I'm not sure.
The GTD UGT110000 gas turbine was being developed by Russia and Ukraine at one point.
According to the page above only two turbines were ever built. One was installed at Kaborga in Ukraine. The other at Komsomolsk HPP, located at Ivanovo in Russia.
Right now it is in limited serial production in Russia by UEC Saturn as the GTD-110M.
UEC Saturn has delivered another three GTD-110 gas turbines after cooperation with Ukraine ceased. Three to the Komsomolsk HPP in Ivanovo, and another one to the Novomichurinsk HPP in Ryazan.

That article makes it seem like the Russian's only home grown choice is the GTU-25P for the Arctic LNG 2 project.
But Russia has the M90FR naval gas turbine in production right now, it is used in the Admiral Gorshkov class frigates. Which is a 20MW engine. That should be resistant to salt corrosion.
Another possibility is to use an electric engine to drive the compressor unit. This is being planned in another liquefaction unit. The Yamal is kind of isolated, but Russia has floating nuclear power plants they could use to provide the power.

China daily isn't exactly a definitive source and I would not treat it as such
this is pretty good efficiency for a large engine. Again, I'm really curious what their combined cycle efficiency looks like
Looks like this is a translation of
I'm not convinced on the stuff about Iran
