The reference to 055 (10000 tone surface combatant, right most picture) states two gas turbine engines. So the poster must made some mistake. We know that 30MW X 2 is in the range for 052D, so either 055 uses 4 of it or something else.An unnamed marine gas turbine. Total output is 30MW, with a thermal efficiency of 40%. I'm not sure how old this image is or its veracity, although the Weibo poster shares a lot of legitimate information. The image seems to imply that it's used on or intended for the Type 055, but I can't vouch for that. Could be an advanced derivative of the GT-25000, although all open sources state an output of below 30MW (around 28MW). The red banner in the background says: "Chinese Academy of Sciences, Institute of Engineering Thermophysics, Advanced Gas Turbine Laboratory".

I think this 30MW is just one of the two(?) known domestically further developed Ukrainian GTs. Not something new.
It is Xue(雪)long(龙) 2, Snow Dragon 2.That's the Yuelong 2 icebreaker moored at the wharf besides the two 055.
