Ship pipe repair in Hon Gai, Vietnam

We start with the leaking, corroded or damaged line, establish the replacement dimensions and connections, then quote fabrication, access, fitting and the agreed inspection or testing. Send the fault photographs and vessel window to our repair team so the first review addresses the section that needs attention.

A leak at a flange, a corroded straight length and a damaged bend can require different work. Identify the line service and mark the fault on a photograph or drawing. Tell us whether leakage occurs continuously or during a particular operation, and whether the vessel has already isolated the line. Our team uses this information to distinguish a connection repair from replacement of a spool, valve or adjoining pipe section.

For a renewal, include the visible limits of the affected area and any known condition findings. A close-up of the hole alone does not establish where sound pipe begins. SVC agrees the section to remove and the replacement scope with the vessel before fabrication. Where inspection reveals additional damage, the revised work and materials need acceptance before we extend the renewal.

Separate urgent temporary attendance from permanent renewal in the enquiry. State what the vessel needs before departure and what can be completed during a later call. Any temporary measure needs its own agreed limits and follow-up; it should not be described in the completion record as a permanent replacement.

Our pipework team prepares the accepted spool to the agreed material, dimensions and connection details. The quotation identifies whether the job includes workshop fabrication only, removal of the old section, onboard fitting, valve work or adjacent repairs. This keeps a replacement spool and a complete line-renewal job distinct when the vessel compares offers.

Before fitting, we check the replacement against the agreed drawing and available installation references. The onboard stage needs room to remove the old section, bring the new spool into place and reach the joints. Tell us about restricted routes, lifting needs, insulation or surrounding equipment at the enquiry stage. These can determine the sequence of work within a short call.

For flanged connections, the agreed scope identifies the mating faces and the required gaskets and fasteners. For welded connections, it identifies the applicable material, joint preparation and welding requirements. Connection checks and acceptance follow the vessel's specified system and repair scope; a visual match is not a substitute for the correct specification.

Agree the inspection and testing before work starts, including the required witness and record. The line service, specification and repair determine what is appropriate. Pressure, medium, duration and acceptance criteria must be defined for that job; there is no single test value for every ship pipe repair. Where class or another appointed party must witness or accept the work, include that requirement when requesting the quotation.

SVC records the sections renewed, materials and connections within its contracted scope, together with the checks actually performed. The handover should identify any outstanding item, temporary measure or deferred test. Materials documentation, dimensional records and inspection reports are included as agreed. The vessel can then distinguish completed fabrication and fitting from work that still requires checking or return to service.

Can SVC quote from photographs?

Photographs can begin the technical review. Add the line service, size, material and available drawing. If essential dimensions or connections remain unknown, we identify what must be measured before confirming fabrication.

Can an old spool be used as a pattern?

It can be a reference where its dimensions and condition are suitable. Confirm the required end positions and flange orientation against the installation, particularly if the old section is distorted or damaged.

Does a spool quotation include valves and testing?

Only the accepted scope determines those inclusions. List the valves, fittings, gaskets, removal, installation and checks required so each can be identified in the quotation and handover.

Can the work be completed during one Hon Gai call?

Send the available hours, access conditions, scope and drawings for review. Fabrication and onboard fitting may need separate stages; completion timing is confirmed against the actual job.
