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

SGT-8000H Service-Friendly Design
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
Easy-to-service design features

Simple and efficient service conceptwith three types of inspections
Combustor Inspection
Major Inspection (Rotor in Place)
Hot Gas Path Inspection (Rotor in Place)

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.

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

Burner and Transition Handling Tool Test
Tool Test 10 / 2013 in Berlin, Germany
Purpose:
Dismantling and assembly of transitions and burners
Dealing with indoor environment
Designed for use of Mobile platform and support cranes

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
May 2015Page 14 Jens Klingemann
SGT- 8000H Serviceability3D model supports service requirements
Destacking Service Option: upending fixture foundation installed during plant construction.
Based on the 3D model the best service concept will be developed and customized, e.g.1. Rotor Inspection can be conducted on site2. Upending fixture foundation installed during plant construction3. Lower cost and higher availability as repair possible without factory visit
