She was 70% ready in 1992. This means machinery was long since fully loaded (it happens well before the launch).
Removing full powerplant from a ship in water is a huge undertaking.
Just about right actually. Carriers normally are very fast ships.

Removing full powerplant from a ship in water is a huge undertaking.
For the non-propulsion related electric load, under the assumption that 003 does not have IFEP, do steam supplied turbogenerators still make sense?

Nope take too much premium space with associated piping, pump. condenser what not. Plus it take a long time to bring it on stream. Small turbo generator has low efficiency! But having said that recently China made a 20 MW compact turbo generator
Li Jie, a Beijing-based naval expert, told the Global Times on Tuesday that the generator unit is now fully operational and technically eligible for production.
Song Zhongping, a military expert and TV commentator, said that the next step will be to install the generator on a test ship, before it is available for use by China's military in one to two years.
The new generation of generator unit made multiple technological breakthroughs and innovative design, the CSIC statement said, noting that 20-megawatts of power is four times as much as China's current generator units and is on par with the most advanced generator units developed by the US and European countries.
Twenty megawatts is sufficient to propel 10,000-ton class vessels, Song told the Global Times, noting that larger vessels like aircraft carriers can use multiple generators to get the power they need.
The new steam turbo generator unit will not only provide electricity for a vessel's propulsion system, but also lay the foundation for a fully electric power system for ships, the company said.
On traditional vessels, power units that provide power for propulsion and electricity are separate, and power generated for the propulsion system is not used to power electrical applications, Song said. Ships seldom sail at full speed, so a considerable amount of its power potential is not used while the electrical system can be overworked providing power to electricity-consuming equipment.
Generators that are powerful enough could be used for both the propulsion and electrical systems, Li said. A ship's power system would be more efficient if one system is used to allocate power to where it is needed.
If you have to have steam turbo generators for your electrical propulsion anyway, then it is probably more space efficient to make the turbogenerators larger to supply the ship’s non-propulsion load as well.
But the flip side is you don’t want all your load to be served by the turbogenerators because that would require some boilers be lit all the time even when the ship is not underway.
That’s why most steam powered, non IEP, warship uses a combination of turbogenerators and diesel generators, split 50/50 in capacity.
With 003, they might have added more diesel generators later after they decided to use EMAL.
Work in progress. I'll continue to update the model as we get better pictures.

What is the gantry crane lifting?
I have no idea, I guess maybe the power unit ?
The windows became bigger ... so the visibility from the bridge would be improved and... as a bonus it would look even better!
