MSO (Minimum Send Out) Compressor is the system for collecting the evaporated gas from the LNG wells, compress it to the desired pressure and feed the discharge header, so that minimum gas is sent out to flair header (to burn out the gas).

In this project, we had developed the application software for the compressor automation.

The level of safety provided by the system is SIL-3 (Safety integration Level-3) with “Fail Safe Hot stand by” configuration. Modbus communication is used to update the real time values to DCS system. HMI displayed all real time values, trip and alarm conditions.
