Drawings are stale
The knowledge left
Data exists, unreachable
Alarms mean nothingPlant types
- Aluminium smelter and metalsContinuous duty, energy per tonne, and control islands that cannot see each other
- Semiconductor and E&EFacility and utility control, scrubbers, and traceability out of closed equipment
- Palm oil millCrop season availability, boiler and steam, downtime by cause
- Water and wastewaterTelemetry, unmanned sites, and compliance reporting that is generated not compiled
Also regularly
Power plant balance of plant. Auxiliary load is where the efficiency quietly goes. Boiler feed and cooling water pumps, cooling tower fans, forced and induced draught fans and mills, switchgear and MCCs. Vibration and bearing health on the large rotating assets, drive current and differential pressure on the fans, and the auxiliary consumption nobody meters separately.
Oil, gas and petrochemical. Pumps, compressors and blowers, fired heaters and exchangers, tank farm and loading. The defining constraint is area classification: instruments taken into a classified area must be certified for it, which sets a cost floor on survey and monitoring work. That floor is never the thing to value-engineer, and a proposal that quietly removes it has changed what it is offering.
Ports, bulk handling and logistics. Conveyors, ship loaders and unloaders, weighing and despatch. The scheduling constraint here is a vessel window rather than a maintenance preference, which changes what a useful maintenance recommendation looks like.
What is the same in all of them
The plant type changes the assets and the vocabulary. It changes the engineering less than people expect.
- The drawings are out of date. Every project starts with reconciling the as-built against the panel, and every honest quotation says so.
- The knowledge left with someone. The person who understood the logic has moved on, and what remains is a program nobody wants to touch.
- The shutdown window is the real constraint, not the engineering.
- The data exists and cannot be reached. The equipment already generates the signal. What is missing is the layer that gets it off the machine cleanly and gives it context.
- Alarms have stopped meaning anything, because nobody rationalised them and now the shift clears the list without reading it.
Questions we get asked
Our plant is not on this list. Is that a problem?
No. The list reflects where we have concentrated, not a limit. The question worth asking is whether the constraint you have is one of the recurring ones above, and it usually is.
Do you understand our process, or just the controls?
We are control and electrical engineers, and we are honest about that boundary. We learn a process well enough to engineer its control system correctly and to ask useful questions, and we expect your process people in the room for anything that changes how the plant runs.
Can you work under our contractor safety requirements?
Yes. Site induction, permit-to-work, method statements and risk assessments are part of normal mobilisation, and for the corridors where we work regularly they are already in place.
