Contrary to many people's perception, Iran may be more advanced than Russia and China in producing heavy duty industrial gas turbines. There was the time of good relationship between Iran and the west before the revolution. During that time Iran acquired licences to produce E class gas turbine. The gas turbine in this news is an improved version of Siemens turbine.
Iranian Turbines for Nord Stream? If that happens then Nord Stream 1 is going to be living on borrowed time.
China and Russia may be in the top tier in indigenous design and produce military engines, but they did not have the time in working on heavy duty industrial turbines. China only reached E, F and H class from 2020s. Russia is even behind China.
If China can first produce a copy then improve on imported design such as Soviet jet engines, I don't see why Iranian can not do the same. The key is the why (it is designed in a certain way) and the hardware to produce, the rest is simple. The Iranian got both from Siemens. Essentially the Iranian GT is like a Mercedes produced in a Chinese factory, should not be a surprise.
