This is a shop visit report prepared by General Electric for Reedy Creek Energy Services regarding a major overhaul of an LM6000 PC Gas Turbine (Engine Serial Number 191-564) conducted at the Houston Service Center. The engine arrived on January 10, 2015, was inducted on January 12, 2015, completed performance testing on March 29, 2015, and finished overhaul on March 30, 2015. The report documents comprehensive findings across all engine modules including the Variable Inlet Guide Vane assembly, Low Pressure Compressor, Low Pressure Compressor Stator and Rotor, Low Pressure Shaft, Compressor Front Frame, Compressor Rear Frame, High Pressure Compressor Stator and Rotor, Stage 1 and Stage 2 Nozzles, High Pressure Turbine Rotor, Low Pressure Turbine assembly, and Turbine Rear Frame. The engine had accumulated 51,443.7 hours since new with 25,000 hours since the last shop visit.

The report details extensive workscope requirements addressing numerous findings including coking, corrosion, wear, erosion, missing components, and damaged seals across multiple engine modules. Major service bulletins were accomplished during the visit including replacements of High Pressure Turbine Stage 1 blades, Low Pressure Turbine Stator shrouds, Variable Bypass Valve actuators, Low Pressure Turbine nozzles with internal cavity coatings, High Pressure Turbine Stator nozzles with thermal barrier coatings, improved Low Pressure Turbine Stage 1 nozzles, and a new T25 sensor. Significant bearing and seal replacements were performed throughout the engine, along with overhauls of compressor and turbine components, manifold repairs addressing dented and gouged fuel manifold nipples, and reassembly and balancing of all major rotor assemblies in accordance with GE specification GEK 98492.

Preface

This is a shop visit report for a General Electric LM6000 PC Gas Turbine concerning ESN 191-564 prepared for Reedy Creek.

An executive summary on the following page identifies the primary reason for the visit with a brief list of service bulletins accomplished during the visit for quick reference.

The remainder of the report focuses on the findings discovered during the disassembly and inspection phase of repair and highlights the work scope required to address the findings and achieve the desired outcome.

Parts identified in the report are primarily non-consumable parts and are presented in part-tracking logs for each module. Each part-tracking log will name the parts removed and the parts installed by part number and serial number. A bill of materials has also been included to indicate new, serviceable or overhauled parts installed during the visit or parts repaired and reinstalled.

A separate schedule of applicable service bulletins has been included to indicate those that were accomplished this visit and others that were verified to have been previously accomplished.

If an engine test was directed by the work scope, a test report charting engine vibration data will be provided within this report. Engine parameter safety reading sheets will also be included in the test report. Any miscellaneous information not previously described in the module findings, work scope or supporting schedules is located in the additional information section.

Throughout the report, selected photos of the engine, its modules or its parts have been included at various stages of the visit. Incoming photos taken while the engine was being inducted are presented first. Photos taken during the disassembly and inspection phase appear with the findings for each module. Outgoing photos taken just prior to outbound shipping have also been included.

All activities described in this report, including any repairs performed by outside service vendors, have been performed in accordance with the applicable GEK 98492.
