Pre-Purchase Vessel Inspection in Vietnam
SVC Marine performs buyer-side pre-purchase vessel inspection for second-hand commercial ships in Vietnam. We attend the vessel, review visible and accessible condition, examine available class and certificate records, document defects and observations, and report practical acquisition and repair exposure to the buyer.
A vessel may appear attractive by age, class, price or location while still carrying machinery, steel, cargo-system, survey or delivery risks that only become visible during technical inspection and document review.
Work packages
- Buyer-Side Attendance
- Visible Condition Review
- Class & Certificate Check
- Defect Classification
- Repair Exposure
- Inspection Report
Our surveyors attend the vessel, inspect its condition and review the available records. The SVC inspection report sets out the findings and repair items for the buyer's assessment.
01
What Is a Pre-Purchase Vessel Inspection?
A pre-purchase vessel inspection is a buyer-side technical condition assessment carried out before purchasing a second-hand ship. It reviews visible and accessible vessel areas, available machinery condition, cargo spaces, class and certificate status, maintenance records, defects, observations and likely repair exposure.
The purpose is not to certify the vessel as fully satisfactory. The purpose is to give the buyer factual evidence and clearly stated limitations before deciding whether to proceed, renegotiate, commission further specialist inspections, prepare a repair budget or stop the transaction.
A normal pre-purchase inspection is based on the condition visible and accessible during the permitted inspection window. It does not automatically include machinery opening, sea trial, underwater inspection, thickness measurement, tank entry, laboratory testing or class survey.
SVC Marine attends as the buyer's technical representative. It is not a classification society, statutory survey authority, flag inspector, valuation company, insurer's surveyor or legal due-diligence adviser, and it does not guarantee vessel condition.
02
What Should the Buyer Learn From the Inspection?
What Are the Material Defects?
Identify visible conditions that may affect safety, class, operation, delivery or immediate repair cost.
What Is Not Available for Inspection?
Record areas blocked by cargo, ballast, safety restrictions, owner limitation or available time.
What Requires Specialist Review?
Identify areas requiring maker, class, engine, electrical, cargo-gear, tanker, NDT, UTM or underwater specialist attendance.
What May Affect the Purchase Price?
Translate major defects, survey exposure and repair requirements into practical negotiation points.
What Must Be Done After Delivery?
Prepare an initial view of drydock, repair, spare-parts, class and operational-readiness requirements.
The inspection must distinguish what was seen, what was not seen, what was reviewed from documents and what remains unverified.
03
Vessel Areas Reviewed During Buyer Inspection
Each zone is recorded separately with its own access status.
01Certificates, Class and Records
Status recorded per document: available, partial, missing, expired, or requires class confirmation.
02Hull, Deck and External Structure
Visual inspection does not replace ultrasonic thickness measurement.
03Cargo Holds and Cargo Systems
Buyer risks: cargo contamination, water ingress, cargo claim, structural repair, cargo-gear downtime, charterer rejection.
04Ballast Tanks and Internal Spaces
Ballast-tank entry is never automatic. Entry depends on permission, gas-free status, ventilation, safety arrangements and available time. Tanks not entered are recorded as not verified.
Visual observation does not confirm internal machinery condition unless dismantling or specialist testing is separately agreed.

How Inspection Findings Are Classified
Every finding is placed in one of five classes. This is what allows the buyer to separate a negotiation point from a walk-away item, and an unverified area from an acceptable one.
Critical Defect
A visible condition that may materially affect safety, class, operation, insurance, delivery or the buyer's ability to trade the vessel.
- Serious leakage
- Major structural concern
- Machinery failure
- Safety-system failure
- Class condition
- Significant cargo-system defect
Major Defect
A material repair or renewal item that may not immediately stop operation but can create significant cost, delay or negotiation exposure.
Observation
A condition requiring attention, monitoring or routine repair but not necessarily a major acquisition blocker.
Document Gap
A certificate, class record, maintenance record or technical document that was unavailable, incomplete or inconsistent at the time of inspection.
Inaccessible / Not Verified
An area or item that could not be inspected.
Unknown condition must not be treated as acceptable condition.
- Cargo
- Ballast
- Safety
- Time
- Owner restriction
- Port rule
- Equipment not opened
- No operational test

Frequently Asked Questions
What is included in a pre-purchase vessel inspection?
The inspection normally covers visible and accessible vessel condition, available certificates, class status, machinery spaces, hull and deck, cargo areas, navigation, safety equipment, records, defects, observations and inspection limitations.
Is a pre-purchase inspection the same as a class survey?
No. A pre-purchase inspection is appointed by the buyer for acquisition decision-making. It is not an official class or statutory survey.
Can every tank and machinery item be inspected?
No. Access depends on cargo, ballast, gas-free status, safety, owner permission, equipment condition and the available inspection window.
Does SVC Marine open the main engine?
Not under a standard visual inspection. Machinery opening, internal inspection or specialist testing must be separately agreed and approved.
Can SVC Marine provide repair-cost estimates?
SVC Marine may provide preliminary repair-exposure comments. Final cost should be based on shipyard, maker, workshop, vendor or specialist quotations.
Can SVC Marine inspect ballast tanks?
Accessible tanks may be inspected where permission, gas-free status, safe access, ventilation and inspection time allow.
Can SVC Marine arrange UTM?
UTM may be arranged separately through an appropriate qualified or approved provider.
Can underwater inspection be added?
Yes, where port permission, diving conditions and access allow. It should be treated as a separate inspection module.
Can SVC Marine inspect a tanker?
Selected tanker inspections may be handled, subject to vessel type, cargo condition, safety restrictions and the agreed specialist scope.
Can inspection findings be used to negotiate price?
Yes. Material defects, survey exposure, document gaps and repair requirements may support further clarification, seller rectification or price renegotiation. The commercial decision remains with the buyer.
Does SVC Marine guarantee that the vessel is suitable?
No. The report records available findings and limitations.
Can SVC Marine continue after purchase?
Yes. SVC Marine may continue with MOA follow-up, delivery attendance, drydock, repair, spare parts and owner-side execution.
