To a novice like me this is amazing and mesmerising stuff.

It's the same to me. And things just got a bit more confusing. John sent me some more drawings about the LP turbine tonight. The LP turbine is different than the one that I've been working. Here are the two versions. Version 1 has a complicated spool shaft with many varying diameters and three reverse turbine wheels at each end. The other has a relatively smooth spool and two reverse turbines on each end. It also has a much more defined input for reverse steam. And the rest of the drawings he sent have more details about the housing. I've asked him to see if he can clarify. They both have 53,000 hp classification. I'm learning on doing the one with the drawings.
This is the one that I've been drawing:

And he's the simpler one: The entire housing seems simpler. When it comes to building a model I should choose the simpler design.

This image might help. This is a pic i took when visiting the ship in August. It's the LP turbine in engine room #1. Notice how the reverse steam pipes lead directly down to the top from each end just like the diagram above. That tells me that the above is the correct version. I'm going to model them without the insulation. BTW: steam pressure entering the LP turbine is 46psi and leaves to 22 inches of hg vacuum.

Great work so far!
