What are the things to be checked carefully during pre-commissioning or commissioning activities for instrument engineer?
Before a plant or facility is handed over for normal operation, it should be inspected, checked, cleaned, flushed, verified and tested. This process is called commissioning and involves both the contractor and operator of a facility.
The transition from construction to operation is the commissioning and startup. Processing plant commissioning embraces activities such as cleaning, flushing, verifications, leak tests, performance evaluation and functional tests essential for bringing a newly installed plant or facility into routine operation.
