Overhaul Procedure
From Shutdown to Reliable Operation
A systematic turbine-generator overhaul process covering preparation, dismantling, inspection, technical assessment, repair, reassembly, testing and return to service.

Planning & Preparation
Before mobilization and dismantling, the team reviews equipment history and prepares all technical, logistical and safety requirements for the overhaul.
OUTPUT: Overhaul plan and site readiness
Shutdown & Dismantling
Controlled shutdown and systematic dismantling of the turbine-generator unit, following established procedures and safety protocols.
Critical dimensions, clearances and equipment conditions are recorded throughout dismantling.
Inspection & Measurement
Comprehensive inspection and precision measurement of all major components. Findings at this stage determine the technical scope of repair and restoration work.
Steam Turbine
Generator
Technical Assessment
Inspection findings and measurement results are evaluated against available OEM requirements, applicable technical standards, operating history and actual equipment condition.
This engineering decision process ensures that repair scope is based on actual equipment condition and technical criteria, not assumptions.
Findings Classification
Acceptable
Within tolerance — no action required
Adjustment Required
Within repairable range — recalibrate or adjust
Repair Required
Damaged but restorable — execute repair procedure
Replacement Recommended
Beyond repair — source and replace component
Repair & Restoration
Execution of repair and restoration work based on technical assessment findings. All repair decisions are confirmed with the customer before proceeding.
Additional repair or replacement is based on technical evaluation and customer confirmation.
Reassembly & Alignment
Systematic reassembly with precise clearance adjustment and alignment. Every step follows technical specifications and verified measurement data.
Precision during reassembly is critical to reliable operation after overhaul.
Testing & Return to Service
The overhaul does not end at mechanical reassembly. A structured testing and commissioning sequence verifies that the unit is ready for reliable operation.
RETURN TO RELIABLE OPERATION
The overhaul is completed only after the unit has been properly tested and returned to stable operation.
Quality & Safety Throughout the Overhaul
Quality control and HSE/safety management are integrated into every stage from 01 to 07 — not as a separate step, but as continuous oversight.
Quality Control Layer
Typical Overhaul Deliverables
Every overhaul produces structured engineering documentation, not just physical maintenance work.
