Field Performance and Dynamic Response Testing

We provide pre-modification performance testing services for older systems prior to replacement, repair, or modifications to characterize current performance. Test results form the basis for recommending repair, retrofit, or replacement, and help set expectations for post-modification performance levels.

We also perform pre-modification mechanical testing services to document the current rotating machinery system’s vibration levels and natural frequencies prior to upgrading or replacing.  Test results are used for dynamic modeling of new or upgraded systems.

Finally, we perform post-installation performance and vibration testing services in new or retrofitted plants, providing 3rd party independent measurements for comparison with contract acceptance criteria.
