Why Shutdowns Are Different from Normal Maintenance
During a shutdown, everything happens simultaneously. PLC programmers are updating control systems while electricians test switchgear. Mechanical teams are overhauling pumps and valves while instrumentation technicians calibrate transmitters. Commissioning engineers are waiting to verify systems as soon as mechanical and electrical work is complete. Inspection specialists need access to equipment that has just been opened.
All of these overlapping workstreams share the same access routes, the same utilities, the same safety permit systems, and the same fixed deadline. If one trade is unavailable or delayed, the consequences cascade across every other discipline. A missing instrumentation technician does not just delay instrumentation work—it delays commissioning, which delays startup.
This interdependence is what makes shutdown staffing fundamentally different from sourcing a single technician for a standalone job. The margin for error is much smaller, and the cost of getting it wrong is much higher.
What Skill Mix to Plan For
Every shutdown has a different scope, but most require some combination of the following disciplines. Planning the right mix—and the right numbers within each discipline—is one of the most important parts of shutdown preparation.
Mechanical
Typically the largest trade group
Pumps, valves, bearings, shaft alignment, heat exchangers, compressors, conveyor systems. Mechanical work usually represents the bulk of the shutdown scope and requires the most headcount.
Electrical
Essential for power and motor systems
Switchgear maintenance, cable testing, motor testing and replacement, protection relay verification, thermographic surveys. Often runs in parallel with mechanical work on the same equipment.
Instrumentation
Critical for process industries
Calibration, control valve servicing, analyser maintenance, safety instrumented system (SIS) testing. Particularly important in chemical, pharmaceutical, oil and gas, and water treatment facilities.
Automation / PLC
Smaller team, critical path
Control system updates, HMI modifications, safety PLC testing, network configuration changes. Usually a small team, but their work is often on the critical path because it cannot begin until mechanical and electrical work is complete.
Commissioning
End-of-shutdown pressure
Verifying that systems work correctly after maintenance, running through startup sequences, loop checking. Commissioning engineers are in highest demand at the end of the shutdown when schedule pressure is greatest.
Inspection / NDT
Regulatory and safety compliance
Thickness measurements, pressure testing, visual inspection, weld inspection, regulatory sign-off documentation. Often required before equipment can be returned to service.
After the Shutdown
Shutdowns are repeat events. Most facilities run them annually or biannually. The technicians who performed well this time are the ones you want to book first next time.
Recording which technicians performed well—and which did not—is one of the most valuable things you can do once a shutdown is complete. On FindFST, mission ratings create a persistent record that makes it easier to assemble proven teams for future shutdowns. Over time, the best shutdown teams are refined through experience rather than assembled from scratch each time.
A brief post-shutdown review of staffing—where the gaps were, which disciplines were under-resourced, which technicians exceeded expectations—provides the foundation for better planning next time. The facilities that run the smoothest shutdowns are the ones that treat each event as an iteration, not a standalone project.
