Technical innovation as the basis of power and
efficiency increase
Evolutionary 3D blading
4 stages of fast acting variablepitch guide vanes (VGV) allowing
for improved part load efficiency
and high load transients
Advanced Can Annular
combustion system
> 60% combined
cycle efficiency
Proven rotor design
(Hirth serration,
central tie rod, internal
cooling air passages)
for world class fast
(cold) start and hot
restart capability
HCO for reduced
clearance losses
3D Four stage turbine with
advanced materials and
thermal barrier coating
High cycling capability due
to fully internally air cooled
turbine section
Transient protection of clearances
for reduced degradation with
hydraulic clearance optimization
(HCO) active clearance control
Performance features
Flexibility features
Designed for >60% efficiency in combined cycle
and best in class operational flexibility

Service-Friendly Design
Easy-to-service design features
 Defined combustor handling tool
envelope (blue frame)
 Utilize engine symmetry to
optimize maintenance tasks
 Provides multi-task environment
 Does not require cover lift for
Combustion Inspection
 Access under engine for
tooling installation
 One toolkit for burner and
transition assembly

SGT-8000H Core Engine
Designed for easy and fast maintenance
All rotating blades including compressor are replaceable
without a rotor lift.
Row 1 Turbine Blades/Vanes/Ring Segments & Row 4
Blades can be replaced with or without cover lift.
Roll out/in capability of the turbine vane carrier enables
exchange of stationary turbine hardware without rotor lift.
Roll out/in capability also allows for optional assembled
spare vane carrier exchange concept which further reduces
outage durations.

Service-Friendly Combustor Maintenance Concept
Benefits
TLC 44 / TLC45 Single Shaft Configuration
 No external crane or other support devices required
 Easy access for Field Service personnel
 Better protection of combustor components against
handling issues
 Pre-assembled burner system for fast installation
 Optimized outage durations due to simultaneous
work flow & packaging

SGT- 8000H Plant Platform Concept
3D Plant Design Model Power Plant Concepts with integrated Service Requirements
1. All power plant components included in the design model
2. Simulation of service activities
3. Optimization of overall power plant concept

SGT- 8000H Serviceability
3D model supports service requirements
Based on the 3D model the best service concept will be developed and customized, e.g.
1. Rotor Inspection can be conducted on site
2. Upending fixture foundation installed during plant construction
3. Lower cost and higher availability as repair possible without factory visit
Destacking Service Option: upending fixture foundation installed during plant construction.
