Commissioning Project commissioning is the process of assuring that all systems and components of a building or industrial plant are designed, installed, tested, operated, and maintained according to the operational requirements of the owner or final client. A commissioning process may be applied not only to new but also to existing units and systems subject to expansion, renovation or revamping.
In practice, the commissioning process comprises the integrated application of a set of engineering techniques and procedures to check, inspect and test every operational component of the project, from individual functions, such as instruments and equipment, up to complex amalgamations such as modules, subsystems and systems.
Commissioning activities, in the broader sense, are applicable to all phases of the project, from the basic and detailed design, procurement, construction and assembly, until the final handover of the unit to the owner, including sometimes an assisted operation phase.
Commissioning of large Civil and Industrial (such as Chemical and Petrochemical Plants, Oil and Gas Platforms and Pipelines, Metallurgical Plants, Paper and Cellulose Plants, Thermoelectric and Hydroelectric Plants, Buildings, Bridges, Highways and Railroads) is a complex and sophisticated technical specialty, which may be considered as a specific and independent engineering discipline, as important as the more traditional ones (Civil, Naval, Chemical, Mechanical, Electrical, Electronic, Instrumentation, Automation And Telecom).
