Suggest that you ask Siemens, I guess that they might know.
The ST5 I think is the old numbering system and that they are now numbered SST (Siemens Steam Turbine). Which SST I do not know, possibly the SST 500 or so.
I am not familiar with the V63 except that it was used by Alstom (Siemens bought out some of the ST business a few years back) and it referred to a casing for a 63 MW machine, but you say yours is a 100 MW so not sure.
