Four step approach for network management

2. Four step approach for network management 1) Select the “best” pipe for inspection. 2) Inspect the pipes 3) assess condition 3a) If the condition of the asset is below a previously defined threshold, repair/replace; 3b) Predict the remaining lifetime, t, of the asset exploiting an appropriate model; and finally 4) Schedule a new inspection after a period, t‘<t.

7. Condition assessment Index for Joint Condition (IJC)

8. Conclusion • Four step approach for network management • Resource optimization: indicates best pipes for inspection • Condition assessment procedure used with any inspection equipment • IJC is a powerful tool that allows comparing several pipes – which one is in worst condition?
