Questions about this reference
What was the objective for the Coentunnel?
To plan maintenance through to 2037, on a plan that holds the required risk profile during project delivery, with inspection results recorded against the same reference.
What does risk-based maintenance planning mean here?
The order of works is set by the risk each component carries rather than by the calendar. That is what allows the restricted risk profile to be met while maintenance cost comes down, instead of treating the two objectives as a trade-off.
Why plan as far ahead as 2037?
Because that is the horizon of the maintenance obligation. Planning to the end of it shows what the whole period requires, rather than what the next budget year can absorb.
What does the operator see?
Visual insights of the area, and behind them the recorded inspection results the plan rests on.
How do inspection results feed the plan?
They are registered against the components, so the plan is built on observed condition rather than on assumption, and can be re-run as new inspections come in.
