Commissioning Description

System

A system is a major subdivision of an installation, being either process or utility, that performs a major operational function of the plant. The system includes all the various equipment that allows it to operate. The firewater pumps, power generation, control systems,

telecommunications, oil, gas, water processing, etc., are typical examples of systems.

Sub-System:

A subsystem is a further subdivision of a system, that performs a partial operational function to the system, with no or little interference from the other subsystems. Several equipment with the same function in the system, main packages are typical examples of subsystems.

Subsystems are Ready For Commissioning when all Precommissioning activities are complete.

  • Subsystems are Ready For Start-Up when all Commissioning activities are complete.
  • Systems or group of Subsystems are Ready For Operation when all Start-up activities are complete.

Pre-Commissioning

The Precommissioning physical scope of work consists, as previously said, in:

  • Systematic conformity checks of equipment items
  • Static/de-energised tests of equipment items
  • Pipes works flushing, pressure test grouped by Test Pack.

Commissioning

The Commissioning physical scope of work consists, as previously said, of:

  • The dynamic verification of the elementary plant functions
  • The running-in and on-line tests of utilities system and the running-in and on-line tests with inert fluid of process system.
  • The Piping and Vessels Preparations.

Start Up

The Start-up scope of work includes activities preparation and witnessing of the commissioning activities. After that, the operational activities properly speaking are split prior to and after oil/gas introduction.

  • Operational activities prior oil/gas in
  • Operational activities after oil/gas in.
