Late to the news, but I don't think this has been posted here before:
The image below is from an academic article, which I believe talks specifically about this generator. It states that the output is 5MW at a rated speed of 1066 rpm. The dimensions are around 11000 mm × 2800 mm x 3900 mm. It weighs <92 tons, with the diesel engine weighing 49.5 tons, the generator set around 23 tons, and other auxiliary equipment about 4 tons.

Speaking of which:
Improved upon the GT-25000 with the addition of intercooler (and recuperator as well?), this could be the intermediate solution that should be able to be ready in the coming years (though not exactly immediately) before the marine variant of the CGT-40 is ready.
Perhaps the 052D/DG-successor class DDG and follow-up classes to the 055 DDG could be its users?

great stuff here
But pretty interesting to see China having such a large market share in dual fuel marine engine now. It has allowed them to establish monopoly in LNG propulsion
China's global market share of marine low-speed diesel engines is 40%, and the global market share of dual-fuel low-speed diesel engines has reached 70%. By 2023, China's global market share of large dual-fuel low-speed diesel engines will be 99%. (dual fuel allows switching to natural gas as fuel)

Excerpts from a research paper hints at a new 35MW marine gas turbine, which is undergoing testing on a special test bench. Its thermal efficiency has reached 40% or more.
The new marine gas turbine (simple cycle) will achieve a rated output power of 35MW under this condition (27°C, inlet/exhaust losses).

FINALLY!!!
This is a massive oversimplification per se (given how marine engines can have varying performances based on many factors, e.g. atmospheric temperature, pressure, humidity etc), and somewhat overstepping myself here - But with this, perhaps China can finally have:
1. An *actual* USN Arleigh Burke-counterpart at ~8-10k tons (with 2x 35MW gas turbine engines + 2x 7.2MW diesel engines (assumed to be adapted from the 054B FFG)) as a general-purpose DDG (plus as a successor to the 052D/DG); alongside even
2. A JMSDF ASEV-counterpart at ~14-16k tons (with 4x 35MW gas turbine engines) as a large DDG or even a CG (plus as a follow-up to the 055)...
