150 MW turbines - continuation

Happy New Year to everyone who visits my blog ... .

I would like to specify what is the scope of work for the rotors, I mentioned in my previous post.
I think, that is a first approach and will be updated after fact finding activity we are doing since the middle of December , so here we have:

1. The HP rotors.
- blasting,
- NDT examination,
- measurement of the rotor's geometry,
- seal strips exchange,
- machining of a bearing journals, seal strips,

This is what I know for today but once any damages are revealed during NDT, the scope of work will be increased, certainly customer has to accept our proposals.

2. The IP rotors.
- blasting,
- NDT examination,
- measurement of the rotor's geometry,
- seal strips exchange,
- machining of a bearing journals, seal strips,
- all stages reblading

Similar remarks like above it had been defined before casings opening, so if customer agrees to accept an additional, necessary works, we will do it.

3. The LP rotors.
- blasting,
- NDT examination,
- measurement of the rotor's geometry,
- seal strips exchange,
- machining of a bearing journals, seal strips,
- reblading of L0 and L1 stages
