Project Scope

Performing an on-site Major Inspection (MI) on a heavy turbine is a critical process that demands meticulous planning, precision, and expertise to ensure the turbine's longevity and optimal performance. This comprehensive maintenance operation focuses on the turbine's hot gas path, where the highest temperatures and stresses occur, making it crucial to examine these components thoroughly for signs of wear, corrosion, or other damage.

1- Proper Tooling: The maintenance begins with the preparation of the site and ensuring that all necessary tools and equipment are available. Providing proper tooling is essential for the efficient execution of the HSE maintenance. The use of specialized, high-quality tools minimizes the risk of damage to the turbine components and ensures that the maintenance can be performed accurately and safely.

2. Hot Gas Path Parts: A key aspect of the MI is the inspection and replacement of hot gas path parts, which are critical for the turbine's performance. This includes blades, vanes, combustion liners, and other components exposed to extreme conditions. Providing original, manufacturer-approved parts is paramount to maintain the integrity and reliability of the turbine, as these components are designed to withstand the specific operational stresses.

3. On-Site Completion: The ability to complete the MI on-site is a significant advantage, minimizing downtime and logistical challenges associated with transporting large turbine components. On-site maintenance requires a team of highly skilled technicians equipped with portable tooling and parts, ready to address any issues immediately and effectively.

4. Professional Execution: The execution of the MI demands a team of professionals with deep expertise in heavy turbine operations and maintenance. This team not only performs the technical aspects of the maintenance but also ensures that all safety and quality standards are met or exceeded. Their knowledge and experience are critical in identifying potential issues before they lead to failures, ensuring the turbine operates reliably until the next inspection cycle.

5. Start-Up Support: After the maintenance is completed, a thorough start-up procedure is essential to ensure the turbine is operating correctly under load. This includes careful monitoring and adjustment of the turbine's parameters, verification of all systems, and support during the initial operation phases to ensure a smooth and safe return to full operational status.

In summary, an on-site Major Inspection of a heavy turbine is a complex but essential process that ensures the long-term reliability and efficiency of the turbine. It requires the right tools, original parts, on-site execution, and a team of professionals to successfully inspect, repair, and restart the turbine, ensuring it continues to meet the energy demands placed upon it.
