Drydock Super­vision in Vietnam

SVC reviews the repair specification before yard entry. We examine known defects, class status and due surveys, the intended docking period, owner priorities and the materials or spare parts needed for each package. Unclear quantities, missing specifications and work that may become a variation are raised before the vessel arrives.

The working list identifies where the repair is to be done, the agreed method, access, inspection points, material source and test or survey requirement. SVC connects those requirements to vendor attendance and the docking sequence. A late part, closed tank or unavailable service team can affect several later tasks, so it is recorded as a programme item.

• Repair areas, known deficiencies and the specification for each appointed job.
• Class due items, survey dates, inspection points and required evidence.
• Owner-supplied and yard-supplied materials, spare parts and expected arrival.
• Access, staging, tank entry, isolations and the work permits needed.
• Vendor scope, reporting format, owner approval items and the intended yard window.

Our superintendent examines the nominated crop-and-renew areas, insert plates, stiffeners and welds. We check access and staging, the planned welding sequence and the inspection or class approval points attached to the repair. Photographs record the condition before work, the stages inspected and the completed area.

SVC checks the relevant hot-work permit and isolation arrangements with the yard and vessel team before the appointed inspection or work proceeds. NDT and ultrasonic thickness measurement records are examined against the areas and requirements on the worklist. Rework, unresolved structural comments and missing evidence are placed on the open-item list.

• Crop-and-renew boundaries, insert plates and structural members.
• Welding sequence, access, staging and the agreed inspection points.
• Hot-work permit status and the work-area precautions required.
• NDT, thickness measurements and relevant class comments.
• Before-and-after photographs, outstanding work and completion evidence.

The nominated engine-room package can include main and auxiliary engine items, pumps, valves, compressors and other auxiliary machinery. SVC examines the repair areas and checks the vendor or workshop work against the appointed scope. Components landed ashore are tracked through workshop work and reinstallation, with the relevant documents retained in the job file.

Our superintendent witnesses the agreed test run, dock trial or sea trial where included in the mandate. The record identifies the equipment, test requirement, observed result and any item still open. Test attendance is planned with the yard, crew and survey programme so that a machinery item is not treated as complete simply because it has been reassembled.

• Main and auxiliary engine work and nominated engine-room repairs.
• Pumps, valves, compressors and auxiliary machinery.
• Workshop landing, service-team attendance and reinstallation.
• Agreed function checks, test runs, dock trials and sea trials.
• Observed defects, outstanding work and the documents required for handover.

SVC checks the nominated service teams on site: their work scope, access, attendance window, equipment and records. The superintendent inspects the assigned work and brings missing attendance, unfinished vendor items or conflicting work sequences into the daily owner report. Each provider’s contracted work remains clearly identified.

Material and spare-part availability is checked against the same programme. Owner-supplied parts and yard materials are recorded separately, including items whose late arrival can delay testing, survey inspection or undocking. The ship supply service carries the separate supply scope when requisitions and onboard delivery are needed.

• Ultrasonic thickness measurement teams and the nominated measurement areas.
• Life-saving appliance and fire-fighting equipment service teams.
• Radio and GMDSS specialists where applicable to the survey worklist.
• Diving and underwater inspection teams for appointed work.
• Coating, steel and machinery workshops and repair vendors.
• Spare-part and supply vendors, delivery dates and missing materials.

SVC checks each variation order against the original specification and the actual work found on board. Our superintendent examines quantities, method, price, relevant class comments and the effect on the docking programme before presenting the item for owner approval. A variation is connected to its physical repair area and evidence, rather than treated as an unexplained addition to the final invoice.

Daily yard inspections record manpower, productivity, vendor attendance and stalled work. SVC identifies the critical-path items that can move the undocking date: late materials, missing specialists, incomplete coating stages, rework, trials and open survey items. The report gives the owner the cost, standby and off-hire exposure of each unresolved item.

Owner-supplied and yard-supplied materials are kept distinct. Where a delivery delay blocks a later activity, the record states the affected work and decision needed. SVC presents technical and commercial facts; the owner approves additional scope, prices and the final commercial decisions.

• Original scope, actual quantity, proposed method and price for each variation.
• Class comments, repair evidence and inspection requirements.
• Yard manpower, productivity and vendor attendance on the vessel.
• Critical-path work, missing materials and unresolved survey items.
• Standby, delay and off-hire exposure requiring an owner decision.
• An active list of open repair, class and variation items through completion.

A second-hand vessel acquisition can bring the first docking forward for class renewal, repair defects or trading readiness. When the acquisition and yard attendance form part of the mandate, SVC takes the pre-purchase inspection findings and agreed delivery conditions into the repair budget and docking worklist. After delivery, our superintendent checks the appointed repair and survey scope at the yard.

Read the container vessel sale and DNV renewal project and the separate ballast-tank inspection work for published field-work records. The pre-purchase inspection and ship sale and purchase service define their own inspection and commercial mandates.

Drydock supervision connects the owner’s worklist to actual yard attendance, tests and handover records. Owner’s representative attendance covers the wider mandate; ship repair and technical work and underwater inspection and hull cleaning define separately appointed repair and diving scopes. The selected yard, dates, personnel and work packages are reviewed for each Vietnam project.
