This course provides each delegate with an applied review of the most common turbine failure modes. Our instructors will focus on early indicators of failures, root causes, and preventative and corrective actions to prevent common failures. The course will also offer an overview on how to perform a root cause analysis and provide many case studies of utility failures.
MODULE 1 – Steam Turbine Failure Modes, and Advanced Troubleshooting Industry failure statistics-locating the areas of highest risk
Common failure modes for steam turbines –explained, impacted components, how to manage and impactflexible operations on each failure mode
High Cycle Fatigue
Low Cycle Fatigue
Stress Corrosion Cracking
Erosion – Solid Particle and Water Droplet
Creep and Embrittlement
Overspeed
Vibration
Generator electrical faults
Generator mechanical failures
• Advanced Troubleshooting – detecting and mitigating before manifesting into a forced outage
• Turbine vibration – unlocking the secrets of rotor lateral and torsional vibration, balancing
• Nondestructive testing – most effective nondestructive inspections to detect known failure modes
• Repair options and considerations – casing cracking, stress corrosion cracking, rotor bow, solid particle
MODULE 2 – Performing a Root Cause Analysis with Case Studies
• Structure root cause analysis process – Kepner Tregoe
