Systemization is the Break down of Facilitiy’s Unit into homogeneous Systems and Subsystems in order to meet mainly following critical objectives:

1)  Scope of Work semplifiction by creating manageable work packages that guide Mechanical Completion (MC) and Commissioning toward a defined Start-Up sequence.
2) Project track progress optimization right through to the Facility Start-Up.
A System is a group of connected equipment that performs a specific operational role—be it process, utility, auxiliary, or safety. A critical characteristic is that this equipment can be isolated from the rest of the facility for individual Testing and Commissioning.
These systems are classified by their primary function:
– Process: Handles the main product (e.g., separation, stabilization).
– Utility:Supplies essential resources (e.g., air, water, power).
– Auxiliary: Provides supportive infrastructure (e.g., control systems, power distribution).
– Safety: Ensures facility safety (e.g., fire suppression, emergency shutdown).
A Subsystem is essentially a fully functional section of a System. It consists of equipment that performs a specific, necessary function for the parent System. Its primary defining characteristic is that it can be independently isolated for its own Testing and Commissioning, separate from the main System’s operations.
