Failure-Mode Coverage, Sensor Health, P-F Timing Margin, Criticality Weighting, Data Availability & Condition-Monitoring Readiness

Marine Condition Monitoring Sensor Coverage & Criticality Tool

Measure whether critical machinery failure modes are actually observable early enough to support maintenance decisions. Simple mode focuses on critical-mode coverage, sensor health, data availability and P-F timing margin. Advanced mode evaluates individual machinery failure modes using criticality, expected frequency, monitoring method, detection effectiveness, data quality and review/response timing to expose high-consequence blind spots.

Data type
↑
Need failure-mode-level coverage? Click Advanced above. Add one row per machinery failure mode with quantity, criticality, annual frequency, P-F interval, sensor modality, continuous/periodic monitoring, sample interval, detection effectiveness, data availability, sensor health, review delay, response delay and channel count.

Fast Critical-Failure-Mode Coverage Screen

Simple mode is intentionally about critical failure modes, not total sensor count. Periodic monitoring receives partial coverage credit, while data availability, channel health and the entered P-F timing window further reduce effective coverage.

Coverage & Data-Quality Targets

Targets are owner / project inputs. They are not ISO, class or OEM thresholds unless the project basis explicitly makes them so.

Machinery Failure-Mode Monitoring Register

One row per failure mode is preferred. Labels are excluded from Ship Universe Tool Data; engineering values and modality enums remain.

Condition-Monitoring Workflow Readiness

Condition-monitoring screening only: this tool does not establish failure probability, guarantee detection, determine safe operating limits, replace OEM alarm limits, approve extended maintenance intervals or establish class credit. P-F intervals, detection effectiveness and expected failure frequency should be based on machinery knowledge, vendor data, fleet experience or a documented reliability process rather than generic assumptions.
