thats a true word,
I only found MAN diesels, available in chinese hands, to power big ships like the varjag and give them a speed of 30 knts;
could someone give us a source or link for another engine?
you can check the china naval power, a couple of weeks back, I posted a list of gas turbines that China has either developed or is under development.

It seems like they have some indigenous/cloning designs ready in the form of QD-168, QC-185 and QC-260, but still waiting to see what ships they go on. Actually this is the gas turbine page of Shenyang Liming, you can take a look at the projects that they have on going if you can read Chinese.

This is a nice listing of the specs of QD-168
Output: 16.8 MW
Thermal Efficiency: 36.5%
Heat Rate (KJ/KW.h): 9896
Exhaust gas flow (kg/s): 64.84
Exhaust gas temp (K): 722
power turbine speed rpm: 5300
alternator rated speed? rpm: 3000
full-life span: 5000 hours
MTBO: 1000 hours
no mention of size

And now, the much talked about QC/QD-185.

It was first shown in Zhuhai 04, this is the one they developed using technology from WS-10A I think.

It talks about in October of 2005, they had CMC, PLAN , AVIC1 officials all attending its unveiling, seems to be a pretty big deal. ...

....
some specs here.
output: 17.8 MW (compared to the current LM-2500, which delivers 25.1 MW, still lagging quite a bit)
Thermal Efficiency: 37.2% (37% also for LM-2500)
Heat Rate (KJ/KW.h): 9710 (6860 BTU/shp-hr for LM-2500)
Exhaust gas flow (kg/s): 58.6 (155 lb/s -> 70.5 kg/s for LM-2500)
Exhaust gas temp (K): 1538 (1000 F for LM-2500)
power turbine speed rpm: 5500 (3600 rpm for LM-2500)
no mention of the size or life expectancy.

Finally, there is also the QD-128, which you can find here

It has a peak output of 13.2 MW and is ready for commercial order.
There are also RO-110, QD-70, QD-45, QD-20, producing 120 MW, 7.1MW, 4.8 MW and 2.1 MW respectively.

As for the mystical QC-260, I assume with the number 260, it's suppose to generated 26 MW of power. Although, I haven't found any official specs on this yet.

I think if QC-185 and QC-260 are more ready, we might see them on the next batch of 052D or 051D.
...

So, we have QC-70, QC-185, QC-260 as what appears to be the 3 types of ship powering gas turbines.
...
Do you think, these engines are powerfull enough to speed the big vessel Varjag up to 30 knts?
