How to Plan Procurement Before Dry-Docking: A Marine Repair Checklist

AI-generated editorial illustration.

Dry-docking compresses a large amount of inspection, repair and certification work into a fixed berth window. Missing one critical gasket, valve, steel insert or certified safety item can leave a vessel waiting while the rest of the yard is ready. Procurement should begin from the maintenance scope and likely findings, not from a last-minute list of items after the vessel arrives.

For operators and business teams

Freeze the docking objective, departure date and operational priorities first. Separate must-have work from conditional work, then assign a long-lead risk to every item. A spare that arrives one day late can cost more in off-hire than its purchase price. Ask suppliers for stock status, manufacturing lead time, export documents, packing dimensions and the latest guaranteed dispatch date.

For technical teams

Build the list from the planned-maintenance system, class recommendations, previous thickness measurements, defect history and maker manuals. Include the equipment tag, drawing revision, material, pressure rating, dimensions, quantity, certification and inspection requirement. For steel renewals, link each plate and profile to the approved repair plan and heat traceability process. For safety equipment, confirm the required approval route with the flag, class or responsible administration; IMO explains that administrations are responsible for approval of marine fire-safety products.

Comparing procurement strategies

Buying everything early reduces schedule risk but increases storage, cash tied up and the chance of specification changes. Buying only after inspection reduces obsolete stock but exposes the docking window to manufacturing and shipping delays. A staged strategy works best: order known long-lead items before docking, reserve conditional materials with the supplier, and release the balance as survey findings are approved.

The handover pack

Require certificates, packing lists, heat numbers, pressure-test records, calibration reports, inspection photographs and delivery notes in a document register. The superintendent, yard and supplier should share one revision-controlled list. Close every item with a received quantity, accepted document and installation location before the vessel leaves the dock.
