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
