Hull repairs and Class notification

RISQ 6.1Section 6 · Ship’s StructureSource marking: V

Applicability: Apply the arrangements and conditions stated in this entry to the vessel.

What is being checked

Hull repairs are reported to Class and appropriately authorised.

Ready on board

0 / 5 checked

Check the vessel’s actual procedures, equipment and records against these points from RISQ 3.2.

Reconcile hull-repair records and visible repair locations with notification to Class and the relevant Class correspondence.Include riding-crew work, such as fracture welding and renewal of deck plating or hatch coamings, including work within holds and ballast tanks.Notify the Classification Society as soon as damage or defects affecting compliance with Class rules are discovered.Consider reduced hull structural capability, breached hull/tank watertight integrity and impaired redundancy or normal operation of propulsion, steering, power generation, auxiliary machinery and associated systems when assessing notification.If uncertain whether a deficiency requires Class attention, obtain clarification from the vessel’s Classification Society.

Practice questions

Preparation prompts derived from this entry, not an official inspector interview script.

1Does using qualified riding-crew welders remove the need to notify Class?

No. The source identifies riding-crew repairs as a concern when not brought to Class attention. Relevant damage and repairs still need Class involvement.

2What should be done if the significance of a defect is unclear?

Contact the Classification Society for clarification, rather than assuming the defect is outside its attention.

Where a finding may arise

Explicit RISQ trigger: record a finding where documents or visual evidence indicate unauthorised hull repairs.

Past observations for practice

Anonymised reports, manually reviewed before publication. These are reported experiences, not additional inspection requirements.

No reviewed observations have been added for this entry.

Share an observation for private review

Remove vessel, company and inspector names, report numbers, exact dates and confidential information. Do not paste a complete inspection report.

Source clarification

The source gives no exhaustive definition of defects requiring notification; it directs owners to Class when in doubt.
