Getting an independant expert opinion on the overall
health of your machine is invaluable.
The RIS service evaluates your machine mechanical
condition and dynamic behavior based on data
acquired by our systems under a wide range of
operating and transient conditions.
It is essential to efficiently manage
your generating assets.
RIS is a vital service for:
- Refurbishment planning
- Tolerance verification
- Warranty term enforcement
- Baseline reference for comparison
- Life extension, and more...
