Steam Turbine.jpg



Steam turbines represent one of the major integrity and safety risks for power generators and industry users. Failure to correctly monitor, inspect and maintain turbines can lead to catastrophic events and considerable losses. In order to make meaningful maintenance and refurbishment decisions, it is essential for the maintenance staff to be aware of the design parameters and considerations which form the basis of the repair scope. This 3 days course offers delegates a firm understanding of the construction and maintenance requirements of steam turbines (covering different designs). This course also looks at some of the more recent development in repair and refurbishment technologies which can offer a cost-effective alternative to conventional techniques.


• Systems Engineers

• Maintenance Engineers

• Procurement Staff

• Maintenance Managers

• Engineering Managers

• Asset Owners/Managers MAIN


• Review of major centre-line components of different design, their arrangements and associated maintenance requirements.

• Understand risks associated with HP, IP and LP Turbines rotors and casings.

• Familiar with common failure mechanism of turbo-generators.

• Overview industry best practice in inspection methods/techniques.

• Selecting the most optimal maintenance strategy.

• Learn how to effectively monitor and manage quality during outages (on-site and off-site work).

• Developing requirements and specifications for sub-contracted work.

• Enhanced decision-making ability in a constrained environment (risk-based decision) taking financial and time impact into consideration.

• Learning about latest technologies options for ease of steam turbine maintenance.

• Learning about global maintenance practices (Case Study).
