Edge for Engineering Solutions is your partner for safe commissioning and start up of your Electromechanical equipments and projects, Commissioning typically falls within three steps:
1. Pre-commissioning: This stage involves activities that occur during the final stages of construction, including pre-functional test (PFT) inspections; end-of-construction punch lists and check sheets; factory and site acceptance testing of control systems; instrument loop checks and more.
2. Commissioning: Sometimes referred to as “cold” commissioning, this second step (in the case of a chemical plant) involves running and testing the process without adding the chemicals or hazardous materials. For building commissioning systems, this step can include pre-functional testing of complete building systems, pre-commissioning focusing on equipment, and commissioning focusing on the system.
Depending on the complexity of the project, commissioning can be executed on individual systems, groups of systems or even partial systems. The commissioning timeline is a function of construction progress, and a commissioning team may be required to modify system commissioning as systems reach construction completion.
Cold commissioning is typically executed by the owner with support provided by the commissioning team. The commissioning team can support the owner with planning and scheduling of activities, manpower requirements for contractor support, and by providing engineering calculations required for various commissioning tests. Some standard tests that may require engineering support and calculations include water system flushing, compressed air blows, temporary support of piping for testing, and steam blows.
3. Startup: This final step is where the plant is finally brought into operation by the owner. During startup, the commissioning team will provide engineering support as required by the owner. A successful commissioning effort generates site-specific knowledge that can be used by the commissioning team to assist in the startup. Some common support functions include operator systems training, process systems troubleshooting, lockout-tagout practices and other safe work procedures, and pre-startup safety review participation.
