Direct answer
Evaluate equipment on total cost of ownership over the intended life, and require an obsolescence and support commitment from suppliers.
What this discipline delivers
- Decisions made on purchase price alone
- Support horizon of control platforms unknown
- No upgrade path planned for installed assets
- Energy and maintenance cost not modelled at purchase
- End-of-life and residual value not considered
Method and stages
TCO modelling
Capital, energy, labour, maintenance, spares, downtime and disposal over the asset life.
Obsolescence management
Support horizon commitments and planned migration windows.
Upgrade path design
Modular architecture allowing later capability additions.
End-of-life planning
Residual value, redeployment or disposal cost assessed at purchase.
Engineering and project considerations
- Ask suppliers for a written support horizon for control components
- Energy cost over 10 years often exceeds purchase price for continuous assets
- Reserve capability for future upgrades in panels, utilities and layout
- Documentation and code ownership protect against forced replacement
- Financing structures can be matched to the asset's economic life
What to prepare before engaging engineering companies
- Expected operating hours and asset life
- Local energy and labour cost assumptions
- Maintenance cost data from comparable assets
- Cost of capital for discounting
What to measure
Frequently asked questions
What life should we assume?
Mechanical bases often exceed 20 years, while control and drive systems typically face obsolescence at 8 to 15 years. Model them separately.
