Gas Turbine Maintenance, Repair And Overhaul (MRO) Activities Are Crucial For Reliable Power Generation
Introduction
Gas turbines play a vital role in meeting the ever-growing power demands across the world. However, to ensure uninterrupted electricity supply, it is imperative that gas turbines undergo timely and proper maintenance, repair and overhaul (MRO) activities. Regular MRO keeps the turbines performing at optimal levels throughout their lifespan.
Inspection and Diagnostics
Thorough inspection and diagnostics are the first steps of any Gas Turbine MRO In The Power Sector activity. Highly specialized tools and techniques are used to inspect turbine components for defects, cracks or corrosion. Infrared cameras, borescope inspections, vibration analysis and oil analysis help detect even the minute flaws inside hard-to-reach areas. Computational fluid dynamics simulations also provide critical diagnostic inputs. Regular inspections as per OEM schedules allow anomalies to be addressed before causing outages or failures.
Component Repairs and Replacement
Repair and replacement of worn or damaged parts is critical to restoring the turbine to an "like-new" condition. Hot section components like combustors, turbines and nozzles suffering from excessive oxidation or erosion are either repaired onsite through welding or replaced completely. Blades and vanes with cracking are repaired through welding or coated with protective layers. Bearings and seals with beyond-repair wear are swapped with new spares. Repairs follow stringent procedures to avoid reworks.
