Governance. Vibration severity is graded against ISO 20816-3. Findings are advisory and are considered alongside operating context and engineering inspection before maintenance decisions are made; all findings in this summary require engineering review before any maintenance action is authorised.

Condition and validated action by equipment

Ordered by severity. The state, the action and the response timing are those recorded in the issued register – nothing is re-graded here.

Temperature trend – all monitored equipment

Continuous sensor temperature for every monitored item, 10 to 18 August 2026. All strips share one vertical scale of 10 to 56 °C so they can be read against each other; the marker is the latest sample.

Coverage. Temperature resolves per equipment node, not per measurement point – the DE and NDE channels of an item share one node and return one series. Eight of the ten monitored items return a continuous signal; the RM2 Pump 2 set returns none and is shown explicitly rather than omitted. Series begin on 10 August 2026, so this window carries eight days of temperature evidence rather than the full report period.

Temperature axis is °C. A trend is included where a mapped sensor signal exists; it supports corroboration of vibration findings and is not a direct girth or trunnion measurement unless that point is explicitly mapped. Source: Optimal Trend monitoring data, 2026-08-06 to 2026-08-13.

Notes – known failures already actioned

Recorded for completeness and excluded from the action counts above. No further action is requested against these items until the stated close-out condition is met.

Known failureActioned
Pump 2 Bearing AssemblyRossing Uranium / Rod Mill 2 / Pump 2 Bearing Assembly (2 measurement points)

Combined V-belt drive and pump-bearing failure on the RM2 Pump 2 set, 20 July 2026 at approximately 03:30, recorded in failure report OPT-RM2-VFR-20260720 (final issue, validation lock applied). The set is out of service under repair; the client-confirmed service-state update of 14 August 2026 records the sensors physically removed. No measurement is expected during active repair.

Closes out on. An authorised return-to-service commissioning record, followed by re-baselining of the drive and pump measurements. Until then this item is excluded from the action counts, from fitted-sensor coverage and from duty-pair inference, and no stale-data or remount action is raised against it.

Provenance. Every state, action and response timing above is rendered from release document condition-register-2026-08-06_2026-08-13.json (schemaVersion 2, sourceRegisterCount 10) as issued in the Rod Mill 2 8-day exceptions report. State definitions, severity gating and response timings are those already defined in routes_client_condition_dashboard.py. The ten-release trend strip reads the public release documents in optimaltrend-api/data/. The RM2 Pump 2 set is presented under notes rather than as an open action on the basis of failure report OPT-RM2-VFR-20260720 and the client-confirmed service-state update of 14 August 2026, both already cited in the issued register. The temperature series are the four mapped exception points carried in the detailed technical report for the same period, recovered from that report’s own plotted values against its stated axis (10 to 51 °C); series are paired to point names in the order the report legend lists them, which should be confirmed against the generator before issue. No state, action, timing, temperature value or note text on this page was authored for the summary.
