Enhanced Platform
Building Block Approach
Using predefined components to
cover different turbine solutions
and applications
The Enhanced Platform is not a product line
The Enhanced Platform is a technology
platform allowing to realize different product
lines such as customized and standardized
turbine configurations as single and multi
casing solutions
Combination of benefits from all Siemens
product lines considering state of the art
developments/technologies
Based on the Enhanced Platform technology
the Siemens product lines will be improved
and extended in their application fields

Blading and Sealing
Improved blade profiles and
material know-how provide
highest efficiency
Improved cylindrical HP blades and
conical (twisted) IP blades allow
longer airfoils
Improved sealing systematic allows more
sealing strips per blade row at both
moving and stationary
3D optimized HP/IP blades reach highest
efficiency, still allowing simple processes
in sales, engineering, and production due
to predefined sub-components
Application of well proven Standard
stages for both fix and geared application

Improved CO2 Footprint
Long-term experiences in material
behavior lead to efficient material
inventory for all components and result
in a total turbine weight reduction
Applying pre-standardized components
leads to reductions in both engineering
and manufacturing effort
Less total weight leads to benefits for
both packaging and logistic
