The SGT-8000H concept uses proven features from Siemens and (former) Westinghouse engines and introduces new technology

5. Technical innovation as the basis of power and efficiency increase
Evolutionary 3D blading
Advanced Can Annular combustion system
4 stages of fast acting variable-pitch guide vanes (VGV) allowing for improved part load efficiency and high load transients
> 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
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
HCO for reduced clearance losses
Performance features
Flexibility features
Designed for >60% efficiency in combined cycle and best in class operational flexibility

6. Global Fleet Overview of SGT-8000H
50 Hz
60 Hz 15 3 15 4 2 8 8 1 6
Siemens has sold 62 units* worldwide so far
H-class fleet has achieved more than starts & EOH*
* 50Hz and 60Hz combined

7. SGT-8000H 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

8. Simple and efficient service concept with three types of inspections
Hot Gas Path Inspection
(Rotor in Place)
Combustor Inspection
Major Inspection
(Rotor in Place)

9. 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.

10. Outage Naming and Duration

with Rotor Lift
35 days
Rotor Inspection -
* Estimated outage durations for turnkey inspections depending on several conditions (labor, site, etc.)
* Shift model: 6 days per week / 2 shifts per day / 10 hours per shift
* It’s working days only, counted form turning gear off to turning gear on

11. SGT- 8000H Service-Friendly Combustor Maintenance Concept
Benefits
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
TLC 44 / TLC45 Single Shaft Configuration
Berlin Factory Test
Installation and Container Concept
Similar baskets and similar assembly procedure for transition
Combustor components pre-assembled prior to delivery to site!

12. Burner and Transition Handling Tool Test
Purpose:
Dismantling and assembly of transitions and burners
Dealing with indoor environment
Designed for use of Mobile platform and support cranes

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

14. 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.
