QUESTION 2.4.1

Onboard defect reporting and shore tracking

Oil, Chemical, LPG, LNGDocumentation, Chief Engineer's Office, Anywhere

What is being checked

The inspector is checking whether officers recognise and report defects affecting structure, machinery and equipment, whether shore management acknowledges and assesses them and whether each defect remains controlled and traceable until effective closure.

Ready onboard

0/7 complete

Practice questions

Answer aloud, then open the preparation point.

1Show the most operationally significant open defect.

Explain failure date, consequence, risk control, notifications, repair plan, target date and continuing verification.

2When does a PMS job also require a defect report?

Use the company threshold: failure, degraded safety function, statutory or class impact, operational restriction or shore-management attention should not disappear inside routine maintenance.

3How are defects found by SIRE, PSC or internal audit entered?

Cross-reference the external finding to the defect or non-conformity system and maintain one consistent closure trail.

4Who can close a defect?

Identify vessel completion authority and required shore acknowledgement or verification under the procedure.

5How is recurrence detected?

Review equipment history, repeat symptoms, cause analysis and fleet alerts rather than treating each work order separately.

Where an observation may arise

UNREPORTED DEFECT

A visible or known reportable defect is absent from the system.

NO ACKNOWLEDGEMENT

Shore management has not acknowledged or evaluated a material defect.

WEAK CONTROL

An open defect lacks risk assessment, interim control, responsible person or target date.

FALSE CLOSURE

The record is closed without repair evidence, test result or required verification.

FRAGMENTED RECORD

PMS, audit, incident and defect records describe the same failure inconsistently.

REPEAT FAILURE

Recurring defects are repeatedly repaired without cause analysis.

Past observations for practice

Human

OP had not included damage to lifeboat water sprinkler line and lifeboat handrail in the defect list.

Human

The fixed tank radar COT 1P was out of order and was not reported in the defect list.

Human

One defective light located in christmas tree was not reported in the defect list.

Master's practical note

Walk one deck and one machinery area before reviewing the defect list. The decisive test is whether what is visibly degraded onboard already exists in the formal reporting system.

Questions reported during inspections

Anonymised user reports, not official OCIMF questions or a prediction of what an inspector will ask.

HumanReported inspection question

The Maker's technician when servicing the X band radar had commented the following - 1.X band Radar Grand Bolt for the Scanner Unit was broken. 2.X band Radar wave guideclamp was cracked and defective. No defect report was raised regarding the Maker's findings. Subsequently the vessel also had occasional failures of the X band Radar unit on 25 Feb 2025, 03 Mar 2025, 13 Mar 2025 and 20 Mar 2025. The defect report was only raised on 01 Apr 2025 after the Scanner motor and Unit completely broke down on 23 Mar 2025.

Equipment boundary and references

Equipment boundary: Not every minor maintenance item requires the same defect process. Apply company thresholds, but statutory, class, safety-critical or operationally limiting failures require transparent escalation.
