Commissioning & Startup

Commissioning verifies that the installed electrical, instrumentation, and automation systems operate as one plant. It is not a single startup event. It is a controlled progression from document review and readiness checks through energisation, I/O verification, functional testing, wet testing, performance observation, issue closure, and handover.

Readiness and Pre-Commissioning

Before energisation, ECCT reviews the latest approved drawings, panel and software revisions, I/O and instrument schedules, control philosophy, network basis, open punch items, and site-readiness conditions. The purpose is to establish a known reference and separate incomplete installation work from automation testing.

Typical pre-commissioning checks include panel condition, supply and control voltages, protective devices, earthing, termination quality, communication hardware, field-device power, drive and instrument configuration, and the availability of utilities required for testing. Temporary supplies, bypasses, and forced conditions are identified and controlled from the start.

I/O and Loop Verification

Signals are tested end to end against the controlled I/O list. Digital inputs and outputs are checked for identity, normal state, command response, and feedback. Analogue loops are checked for range, engineering units, scaling, direction, and fail behaviour. Communication-based devices are checked for addressing, mapped data, diagnostics, and the plant response to communication loss.

Equipment tests combine command and proof. A motor command is verified with starter or drive response, run feedback, trip feedback, selector status, and applicable permissives. A valve test includes command, movement, end-position feedback, timeout, and fail position. This approach avoids closing an output as “tested” when the associated feedback or interlock path remains unverified.

Functional and Sequence Testing

After I/O confidence is established, the system is tested against the control philosophy. Manual modes are checked within their approved boundaries, followed by automatic sequences, state transitions, interlocks, alarm consequences, duty/standby transfer, restart behaviour, and abnormal scenarios. Dry testing is used where the process cannot yet be introduced safely; wet testing then confirms behaviour under actual flow, pressure, level, temperature, and timing conditions.

Changes required during startup are handled through controlled issue records. Each change identifies the observed condition, affected device or software function, agreed action, responsible party, retest result, and whether the change is temporary or final. This prevents working adjustments from becoming undocumented differences between the plant and the delivered records.

SAT, Handover, and Operating Knowledge

Site acceptance is supported by test evidence rather than a general statement that the plant is running. The final record should show what was checked, what was changed, what remains open, and which revision represents the as-commissioned system. Software backups, parameter sets, alarm and setpoint records, marked-up drawings, and issue lists are aligned before handover.

Operator and maintenance handover focuses on equipment states, command sources, permissives, interlocks, alarms, reset conditions, manual limits, and recovery from common abnormal conditions. The objective is to leave the plant team with a system they can understand and maintain without depending on undocumented knowledge held by the commissioning engineer.
