After the installation or major maintenance of a gas train, an organized commissioning must be performed before it is put into regular operation.

Inlet pressure

The upstream pressure is recorded at low and high load.

Regulator setpoint

It is confirmed that the downstream pressure remains stable and within the permissible limits.

Monitor and slam-shut

The setpoints and the correct activation sequence of the protection devices are checked.

Pressostat

Low and high gas pressure switches must be at the correct values to provide protection without unwanted trips.

Documentation

The final pressures, settings, and test results must be recorded for future maintenance and diagnostics.
