Urgency Classification

Overview

After synthesising root causes and assigning confidence levels, the IOT Manager classifies the overall investigation urgency into one of three tiers. This classification determines the visual presentation of the final report (banner colour) and sets expectations for the engineering team on response timing.


The Three Tiers

IMMEDIATE — Hours

Action required before next BWTS operation.

A compliance breach is active, a safety risk exists, or the system cannot operate within regulatory limits. The report header displays a red banner.

Response window: Hours

SHORT-TERM — Days to weeks

Address at next port call.

A degradation trend is confirmed and will breach compliance if uncorrected, or preventive maintenance is overdue on a critical component. The report header displays an amber banner.

Response window: Days to weeks

MONITOR — Next scheduled review

Watch and log.

A minor deviation has been detected or an early warning signal is present, but no compliance breach or safety risk exists today. The report header displays a blue banner.

Response window: Next scheduled review

Decision Matrix

The IOT Manager determines urgency by evaluating three factors together: the severity of the root cause, the magnitude of the parameter deviation, and the compliance status.

SeverityDeviationCompliance StatusUrgency
Component failure or safety riskParameter beyond operational limitNon-compliant (breaches IMO/flag state requirement)IMMEDIATE
Component failure or safety riskParameter beyond operational limitCompliant (within regulatory buffer)IMMEDIATE

Example Scenarios

UV Intensity Below Compliance Threshold

Situation: UV intensity on BWTS-UV-003 has dropped to 18.2 W/m², below the 25 W/m² IMO compliance threshold. 13 of 16 UV lamps are past their rated operational life. The system cannot guarantee ballast water treatment efficacy.

Why IMMEDIATE:

  • Active compliance breach (below IMO threshold)
  • Safety risk (untreated ballast water discharge)
  • Root cause confirmed with HIGH confidence (lamp degradation)

Report banner: Red — “IMMEDIATE ACTION REQUIRED”

Expected response: Replace UV lamps before the next ballast water operation. Do not operate BWTS until repairs are verified.


Urgency and Confidence Interaction

Urgency and confidence are independent assessments that combine in the final report to give the engineering team a complete picture.

ConfidenceUrgencyReport Presentation
HIGHIMMEDIATERed banner. Root cause prominently displayed with full evidence. Remediation procedures listed as mandatory.
HIGHSHORT-TERMAmber banner. Root cause confirmed. Remediation procedures listed as recommended.
HIGHMONITORBlue banner. Root cause known but impact is minimal. Procedures listed as optional/preventive.
MEDIUMIMMEDIATERed banner. Root cause listed with caveats. “Requires validation” note. Procedures listed as precautionary.
MEDIUMSHORT-TERMAmber banner. Root cause plausible. Procedures listed with “verify before acting” guidance.
