Successful Automation Commissioning Starts Before Startup

Decisions made during design can shape how an industrial control system performs when it is placed into service. Integrating automation, testing and operator input earlier in project delivery can help teams resolve issues before they complicate commissioning and startup.


Everything may appear to be going according to plan on an industrial automation project until boots hit the ground for commissioning, and the team comes face-to-face with details, dependencies and site conditions that have not been accounted for.

At that point, the control system must interact with equipment in the field, operators need to use it as intended, and individual components have to function as parts of an integrated system.

An issue that seemed minor during design can suddenly affect startup activities, an outage window or the broader project schedule. For example, an unanswered design question could become a field decision or an overlooked interface could become a troubleshooting exercise, consuming unbudgeted time from the startup schedule.

While the problem might first surface during commissioning, its roots could trace back to decisions made or details overlooked much earlier in design. As automation becomes increasingly connected to the design, construction and operation of industrial facilities, commissioning readiness needs to begin much earlier. Bringing automation into the project alongside engineering and construction can help teams identify integration challenges while there is still time to address them, rather than discovering them when the system is otherwise ready to go live.

Integrating Automation With Design

Industrial automation touches numerous elements of a facility. Instruments and devices throughout a plant connect to control systems that respond to changing conditions, while human-machine interfaces (HMIs) give operators visibility into and control over those processes.

In many projects, automation is delivered by a system integrator working separately from the engineering and construction teams. Such separation can create additional work for people designing the facility. Waiting until later stages to resolve control system questions can compress the time available to address them. Earlier involvement creates more opportunities to uncover conflicts before those conflicts reach the field.

When automation professionals work alongside other engineering disciplines, control system development can progress in parallel with mechanical and electrical design. Additionally, automation considerations can inform design decisions earlier, helping engineers identify equipment, instrumentation and interface requirements that will eventually affect programming and commissioning.

Moving Troubleshooting Earlier

Factory acceptance testing, simulation and off-site PLC, and HMI testing can move troubleshooting earlier in the project. Devices, networks and instrumentation also can be configured before field commissioning when practical. For example, establishing communications with a tank gauging remote terminal unit (RTU) or motor-operated valve controller before commissioning allows the team to verify that the control system can communicate with those devices. Identifying communication issues at this stage provides time to troubleshoot them before they can affect the cutover or commissioning window. On brownfield projects, evaluating existing equipment and systems before integration can reveal conditions that might not be captured in drawings or documentation.

Each issue resolved in the office or panel shop is one less issue competing for attention during a limited commissioning window. It is vastly easier to engineer solutions in the quiet of a controlled environment than in the field. The goal is to arrive on-site with fewer unknowns and more time to address the conditions that only the field can reveal.

Bringing Operations Into the Conversation

Early integration is not limited to engineering disciplines. Operations and maintenance personnel can provide important perspectives before a system is placed into service.

On one fuel facility project, a view-only HMI and preliminary control system components were installed alongside the existing control system. The arrangement allowed the project team to use real field data to establish and test communications before the final transition. By cutover, operators had already spent about a month with the new interface, working with live data and suggesting improvements. Their first opportunity to influence the system, offering feedback from actual use, came while there was still time to change it. More than anything, that extra time allowed them to take ownership of the system early on, making the transition feel natural.

That early involvement provided an opportunity to evaluate more than whether the technology worked. Operators could see how information would be presented, become familiar with the new system, and provide feedback based on how the facility was operated.

The same approach can apply throughout design. Operators, electricians and other personnel who understand existing equipment and day-to-day processes can identify details that may not be apparent from design documentation. Their input can help connect the intended automation strategy with operational realities.

Training and knowledge transfer also can begin before handover. By the time commissioning arrives, the people responsible for the system have already had opportunities to understand how it is intended to work.

Treating Cutover as the Result of Preparation

When commissioning and cutover begin, preparation across the project comes together. At this stage, a commissioning schedule should account for more than the sequence of technical activities. It should establish how the facility will continue to operate throughout the process and what each participant needs to accomplish along the way.

For operators, that means identifying how they will control the system during different stages of commissioning, when their involvement will be required, and which system settings or operating parameters may require closer attention. For subcontractors, the schedule should establish when personnel need to be on-site, how technicians will be assigned and when progress should be evaluated. Clearly defined milestones give the broader project team a shared understanding of whether commissioning remains on track.

Documentation requires similar preparation, during which engineering and construction personnel should review drawings and supporting information before crews enter the field. Page-turn meetings can help teams walk through the planned work together and clarify responsibilities, helping identify installations that may require additional instructions or supporting documentation.

Commissioning typically involves conditions that cannot be fully replicated beforehand. But there is an important difference between responding to an unforeseen field condition and resolving a coordination issue that could have been identified months earlier.

Automation may represent a specialized portion of an industrial project, but its connections extend across the entire project. Treating it as an isolated scope can leave important interfaces unresolved until the project reaches one of its most time-sensitive stages. Integrating automation earlier creates opportunities to address those interfaces throughout project delivery. By the time cutover arrives, commissioning becomes less about determining how individual pieces fit together and more about validating the preparation that has already occurred.
