The work describes essential degradation modes affecting critical components and proven methods of restoration. Sections discuss key elements of life extensions for aging units and components, together with critical reviews of available methodologies. Coverage includes advanced nondestructive testing methods essential for effective life extension programs, including lessons learned from firsthand experience working with multiple machine designs, classes and operating conditions.
The final sections cover a body of solutions intended to refocus ORM processes on overcoming the shortfalls caused by volatilities and system restructuring.
- Reviews best practices for practitioners seeking to make decisions on gas turbine maintenance, repair and operations
- Analyzes components and major sections in terms of functionality, critical features, residual properties and service caused damages
- Explains the applicability and limitations of special processes and advanced non-destructive testing methods
