Local deterioration can change priorities across the plant.
A machine’s condition alone is insufficient to decide where to act. You also need to know which function it provides, which equipment depends on it and what fallback options exist.
A concrete example
Pump → cooling → compressor
The pump supplies the circuit that cools the compressor. This is a functional relationship: degraded cooling can expose the compressor even when its own condition remains satisfactory.
Pump
Deterioration is observed on the equipment that circulates the fluid.
Supplies the circuitCooling
The function depends on the pump’s flow and circuit conditions.
Cools the compressorCompressor
Loss of cooling can constrain operation and affect production.
- Possible consequence
- Pump deterioration may degrade cooling, then limit compressor service. A dependency does not mean a shutdown is certain.
- What changes priority
- The function served, exposed equipment, operating conditions and any redundancy. The most degraded machine is therefore not always the first to address.
- Options to discuss
- Check the deterioration, maintain service with a fallback if one exists, or prepare an intervention within the available window.
- Justify the choice
- Compare the consequences of deferral with intervention constraints. Evidence, assumptions and documented dependencies explain the order of actions.
An asset’s role and dependencies explain its potential impact on production.
How it works
From a technical relationship to a defensible priority.
- 01
Name the relationship
Describe what the equipment provides to the process: supply, cooling or drive. Links must be documented within the plant context.
- 02
Compare conditions
Read equipment deterioration alongside dependent equipment condition and operating conditions. Keep unknowns explicit.
- 03
Prepare the trade-off
Compare exposure, calculation assumptions, intervention cost and available resources, then discuss actions with your teams.
On your site
REX, for dependencies within your scope.
- What the offer covers
- Equipment monitoring and documented dependency analysis, with the decision and planning views already presented on REX.
- What to define
- The assets, usable data sources and functional links to document or check with your teams.
- Analysis limits
- An undocumented relationship or missing measurement limits conclusions. Dependencies support a trade-off; they do not provide a certain failure date.
Which function depends on your critical equipment?
Start with a line, workshop or equipment family to discuss your sources, dependencies and decisions to prepare.
