Turbine generator failures are likely to result in a significant loss of income. An informed technical understanding of the cause is critical to ensuring maximum availability and flexibility. When vibration problems are encountered, detailed investigation and the determination of plant condition, including risk arising from continued operation, is key.

Vibration Diagnostics can write procedures, liaise with Original Equipment Manufacturers, provide site investigation equipment and undertake further detailed tests to isolate fault conditions that cannot be located with the turbo-visory or installed instrumentation package.

This may include:

• rotor balance problems on return to service
• cold to hot turbine alignment issues
• sticking pedestal sliding surfaces and excessive tilt
• white metal bearing performance and failure mechanisms

Vibration Diagnostics can participate in full investigations with you and your plant supplier to identify and rectify turbine generator or key auxiliary plant problems.
