Here is the google translation. Apparently they make a lot of modification on the original Varyag propulsion.to improve reliability.The main change is They lowered the Steam operating pressure in high speed, and maybe compensated it by using larger steam turbine. They say it eliminate problem that still dogged Kutznetzov. There is video link that show excellent condition of the propulsion system here it is. I see a lot of J 15 on the runway. Did intrepid said 10?
A few days after welcoming the commander-in-chief of Russian naval forces to his home base, Chinese aircraft carrier Liaoning has left for a new training campaign.
The duration and exact location of this trip was not formally communicated, but it can be assumed that the aircraft carrier left its base near Qingdao and returned northward before reaching Bohai Bay where it The habit of training.
Three notices issued by the Chinese Maritime Safety Administration, which indicate several zones of prohibition of navigation active from 6 to 18 November, seem to confirm this hypothesis.

Of these three areas, the northernmost one is only 15 kilometers from the Chinese carrier training center, where two new test tracks with catapult were recently inaugurated (see our file "The Chinese Navy is starting Catapulting tests').
It is unclear at this time whether the aircraft carrier Liaoning will also participate in the catapult test program, notably to test the landing of the J-15 catapultable version.
Meanwhile, the Chinese Army has published about 20 new photos on the recent activities of its only aircraft carrier. Through these photos, there are at least 8 J-15 aircraft on deck, and the crew continues to train on various subjects, such as sending and recovering aircraft, fast reloading Ammunition or the fight against fire ... etc.
It is rare for the Chinese Navy to broadcast pictures of Liaoning's weapons systems, but this time we can see not only the HW-10 HQ-10 missile and H / PJ-11 gun fire, But also the presence of anti-diver's rocket launchers on the Chinese aircraft carrier.
The national television channel CCTV-7 also broadcasted a report in its newspaper of 8 pm on the senior NCOs working in the machine compartments. This short film of 4 minutes showed us several unpublished images on the propulsion of this carrier of 50 000 tons.
When the ex-Varyag was sold to China, propulsion systems were the few parts of the ship that remained in a proper state. The Chinese engineers then analyzed all the systems and implemented more than 1,000 modifications in order to improve the stability, the reliability and the overall performance of the propulsion.
One of the major changes is to reduce the pressure in the boiler pipes, in order to prevent boilers from operating systematically in over-speed mode when the vessel exceeds 18 knots, a problem that was present on its sistership, the Russian aircraft carrier Admiral Kuznetsov.
