Process machinery continues to run for many decades. During this period several changes occur in their environment and there is often the necessity to introduce modifications in their structure to let them continue their service in the new situation thus allowing savings in the investment. Typical examples of the modifications that can be introduced on existing rotating machinery are the following:
- Modifications for new operating conditions
- Modernization of machinery components
- Upgrading with new technology
- Restoring damaged units
- Debottlenecking
