A hull-repair file should explain how the completed work relates to the approved repair definition. A folder full of certificates is not enough if nobody can connect a record to a particular location, revision or inspection stage. Hull repair welding inspection documentation is most useful when the owner defines that connection before work begins.

This is a document-coordination guide for owners and superintendents. It does not prescribe a welding procedure, inspection extent or acceptance criterion. For the initial work description, see preparing a hull steel renewal scope.

1. Start with the applicable repair definition

List the repair drawing or technical instruction, its revision and its approval status. Record the vessel’s class and any relevant flag or owner requirements, but do not assume that a generic checklist settles them. Where review or attendance is needed, identify who will obtain it and what information that party requires.

Statutory verification and classification are related but distinct responsibilities. The IMO explanation of surveys, verification and certification describes the role of flag Administrations and authorized organizations. It is not a project-specific inspection plan or evidence that any particular yard holds an approval.

2. Give every record a repair-item reference

Use the same location or repair-item identifier across drawings, material records, inspection requests and completion documents. Where a weld map is part of the agreed package, align its identifiers with the repair drawing. This avoids a common handover problem: valid-looking reports whose physical location cannot be established.

  • Vessel and repair-item reference.
  • Document number, revision and issue date.
  • Physical location or drawing reference.
  • Author, checker and intended recipient.
  • Status: proposed, reviewed, accepted or superseded.

Keep status labels meaningful. “Received” should not be used as a substitute for technical review or acceptance.

3. Agree the evidence required before fabrication

Discuss which material, welding and personnel records are required for the actual repair. Depending on the approved scope, the package may reference material identification, applicable procedure documentation and qualification records. The responsible technical parties must confirm relevance and validity; this article does not declare a universal certificate set.

Identify who checks the documents and how comments are closed. An early missing-document list is more useful than discovering at handover that a required record was never requested. It also makes technical expertise visible through traceable review rather than unsupported quality slogans.

4. Plan inspection requests and release points

Use the agreed inspection plan to distinguish routine checks from points requiring notification, witness or release. Record the necessary notice, responsible person and evidence of completion. Do not cover or close an area before resolving any applicable inspection restriction.

Inspection method, extent and acceptance criteria must come from the vessel-specific requirements and responsible technical authority. Do not replace them with an assumed percentage or a standard copied from another vessel. Log any required reinspection and link the final disposition to the same repair item.

5. Keep findings and closures together

An inspection report with an outstanding finding is not a closed item merely because the report exists. Maintain a findings register showing the location, reference, assigned action, supporting evidence and closure authority. Preserve superseded reports where needed to explain the sequence, while clearly identifying the final applicable record.

Separate three decisions

Document receipt, technical acceptance and commercial completion may be handled by different people. Recording each separately helps avoid an unintended acceptance statement in an email whose purpose was only to acknowledge an attachment.

6. Build a searchable handover index

The final index should lead from the repair item to the applicable drawing, relevant material and welding records, inspection results, resolved findings and final status. Check that links work and document revisions agree. Note any outstanding documents explicitly instead of describing the package as complete prematurely.

For a steel and structural repair enquiry, include the proposed evidence register and known review interfaces. Discuss the documentation boundaries with Gisan Shipyard before assuming a particular inspection or handover scope.
