Chinese Marine Propulsion

- Start date
Looks to be patent application related to the aero-derivative, 40MW-class QC400 intercooled marine gas turbine engine, which is jointly developed by AECC and CSSC.

We may actually see both simple-cycle CGT-40M and intercooled QC400 onboard next-gen PLAN warships in the future.

To further expand on the bolded sentence:
It has been observed (from academic papers/patent applications/tender documents) that the CGT-30M/40M can be utilized for both ship propulsion and shipboard power-generation, whereas the QC400 will only utilized for shipboard power-generation.
That is:
1. DDGs (& potentially FFGs) using CODLAG/CODLOG systems with CGT-30Ms/40Ms driving propeller shafts (and diesel engines providing power to electric propulsion motor and shipboard power usage); and
2. LHD/As and CVs (& potentially CGs) using IEP system with CGT-30Ms/40Ms and/or QC400s generating power for ship propulsion and shipboard power usage (with or without combination with diesel engines).
In fact, China could quite well be the only country to have two different 40MW-class gas turbine engine models employed onboard her warships in the coming future.

"With a maximum power output of 64,500 kW, the 1,953-tonne engine achieves over 95% methanol replacement for diesel fuel and cuts CO2 emissions by over 7.5%."
According to this blogger, the power generation capacity of QC400 is 50MW class.
Probably best to take his takes with a grain of salt... I find some of them are... kinda wild...
Apparently he said that the 50MW figure is confirmed.
So if the claim is accurate and WS-10-derived QC400 made it onboard future PLAN warships - Then China is definitely making history. Namely, the first ever marine gas turbine engine of the 50MW-category in the world.
Per my observation thus far, he seems reliable. And without anyone on Weibo that is comparable to him in the fields of Chinese marine propulsion systems enough to be an alternative for the time being, he's my go-to source.
