Compliance Monitoring Tab

Live IMO D-2 and USCG compliance status, treatment effectiveness summary, and system event audit trail.

Compliance Monitoring — five live regulatory checks with status indicators

What this tab shows

The Compliance tab performs real-time checks against two international regulations — IMO D-2 and USCG — using the most recent telemetry record. It also tracks treatment effectiveness, maintenance record status, and certification validity in one consolidated view.

Data sources:

• /api/telemetry/latest — for all live compliance values
• /api/events?limit=20 — for the audit trail

Summary stat row

Stat	Description
Compliance Rate	Percentage of the five compliance items that show COMPLIANT
Active Certifications	Total number of compliance items being tracked
Latest Check	Timestamp of the most recent telemetry record used for checks
Issues	Count of items showing WARNING or NON-COMPLIANT

The five compliance items

#	Item	Logic	Compliant threshold
1	IMO D-2 Standard	UVR_INTENSITY >= 252	≥ 252 W/m²
2	USCG Type Approval	UVR_INTENSITY >= 530	≥ 530 W/m²
3	Treatment Effectiveness	AVG_LAMP_EFFICIENCY >= 70	≥ 70% average lamp efficiency
4	Maintenance Records	FAILED_LAMP_COUNT === 0	Zero failed lamps
5	Certification Validity	Static expiry date check	Certificate not expired

Status indicators

Icon	Status	Meaning
Green circle (✓)	COMPLIANT	Threshold met
Yellow circle (!)	WARNING	Marginal zone — threshold approached or partially met
Red circle (✗)	NON-COMPLIANT	Threshold not met — action required

Treatment Effectiveness panel

Three horizontal progress bars show how far current values are from their compliance thresholds:

Bar	Calculation	Full =
IMO D-2 Compliance	UVR_INTENSITY / 252	100% at 252 W/m²
USCG Compliance	UVR_INTENSITY / 530	100% at 530 W/m²
Avg Lamp Efficiency	AVG_LAMP_EFFICIENCY	100% at 100% efficiency

Each bar shows the actual numeric value below it. Use these bars to monitor proximity to threshold limits — a bar at 80% of fill means there is a 20% margin before non-compliance.

Audit Trail

System event audit trail showing the last 8 process events

The Audit Trail panel shows the last 8 system events in reverse chronological order. Each entry displays:

• Timestamp — UTC datetime of the event
• Event type and description — human-readable summary
• Result — PASS for process start/stop events, ALERT for alarm events

Event type	Displayed result
PROCESS_START	PASS
PROCESS_STOP	PASS
ALARM_TRIGGERED	ALERT

Important limitation

The Compliance tab performs real-time checks on the most recent telemetry record only. It does not query a stored compliance log or historical compliance record. For official record-keeping and regulatory submissions, use the Data Export tab to download complete timestamped telemetry covering the full voyage period.
