Root cause analysis
Prevention by determinaton of the root cause
When an incident occurs, you need to understand why in order to ensure it never happens again. Sulzer can perform root cause failure analyses for gas and steam turbines, centrifugal, axial, and screw compressors, as well as hot gas expanders.
Using state-of-the-art techniques and technologies, our experienced personnel can help you determine the factors that led to the incident.
