Asset Health Register

Demonstration data. Synthetic Marsden Point records as at 28 October 2026, not Channel telemetry, contracts or inspection evidence. Rates and costs are assumptions to confirm with Channel. Connect the terminal management system, historian and SAP PM to replace them.

Colour is condition: floor, shell, coating, inspection currency and settlement. Amber rings mark tanks whose score moved this week.

Highest-risk tanks

7 tanks are HI4 or worse, but 7 of them are empty and carry little risk until they are repurposed.

Risk matrix

Probability of failure against consequence; bubble size is annual risk. Click a bubble to open the asset.

Common-cause watch

Assets that share design, make, age or protection zone tend to fail the same way. 12 defects point at 42 siblings worth checking · NZ$604k/yr exposure if the cause is shared.

Trigger: · Last PST failed to reach 10%
Shared: Same actuator model, same proof-test procedure.
Checking costs about NZ$27k. If the cause is shared, sibling failure probability rises by an assumed 50%, worth NZ$138k/yr.

Cohorts (make, model, CP zone, construction era) are DEMO assumptions; age-driven factors and location-specific threats are excluded because they are not common-cause signals.

The curve flattens: the first NZ$200k removes NZ$425k/yr. Assumes each intervention removes 70% of the asset’s risk.

Method: CNAIM-style health index → probability of failure → × consequence = monetised risk; tank limits follow the API 653 pattern and pipeline segments the API 1160 / ILI pattern. All limits, curve constants, costs and segment values are DEMO assumptions to calibrate with Channel’s inspection data before any engineering use.
