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...
