Guides for design of turbine generator design? 1

[FieldVerify]

Are there any good books or guides for the design of a turbine generator pedestals for simple and combined cycle plants? I have found some decent (but not great) guidance for the design of concrete pedestals but nothing for steel or spring supported turbine foundations. Maybe the smart folks here at eng-tips know of something?

The companies (Black and Veatch; Bechtel; Sargent and Lundy; etc.) that do these have their own guidelines.
But it's important to know what size you're talking about. When you say a combined cycle power plant I'm thinking something over 300 megawatts. And there's no way they hand that to a guy (or gal) who expects to find design in a book. It's very hands on, generation to generation designs.
Now if it's something that's the size of a flatbed built by a manufacturer like Caterpillar and about 20 megawatts, that's different. Still no book, it usually is just a chunk of concrete that weighs three times the mass of the generator.

Agree with JedClampett. For the electric utility sized units (300 megawatt & up), turbine generator pedestal design is site specific. They are "tuned" so that they resonate to cancel out the miniscule turbine generator vibration at synchronous speed. To do this, not only the detailed soil properties must be known but also the pedestal's foundation design (piling, drilled pier, spread footing, etc.)

I have a book that addresses this: 'Design of Large Steam Turbine-Generator Foundations' (by ASCE, 1987). Overall it's pretty good, although a bit generic (and somewhat dated by this point). One thing to get ASAP is geotechnical information (as another poster has said). And that starts with a firm that really knows what they are doing in this area because increasingly I've had a hard time getting dynamic soil info out of a lot of these outfits (many don't seem to know much about it; I've had to hold their hand in some instances).
