SVC Marine — Port Call Control & Evidence
Port Captaincy & Bunker Survey Services in Vietnam
SVC Marine provides port captaincy, bunker survey, cargo-operation attendance and marine field reporting for overseas principals requiring reliable local representation at Vietnamese ports, terminals and anchorages.
Our team attends the vessel, records operational events, monitors cargo or bunker activities, preserves photographic and documentary evidence and reports material exceptions directly to the appointing owner, manager, charterer, trader or cargo interest.
When the principal is thousands of kilometres away, a delay, cargo incident, bunker discrepancy or stevedore issue can become a commercial dispute before the office receives a clear account of what happened.

SVC Marine port captain attending vessel and cargo operations at a Vietnamese port.
What Does a Port Captain Do During a Vessel Call?
A port captain attends a vessel or cargo operation on behalf of an owner, charterer, operator, trader or cargo interest and provides an independent local view of loading, discharge, stowage, cargo handling, lashing, delays, damage and operational events.
The port captain does not replace the vessel master, terminal, stevedore or ship agent. The role is to observe the operation from the appointing principal’s perspective, preserve factual records and promptly report events that may affect cargo, time, vessel condition or commercial exposure.
Depending on the mandate, attendance may be continuous, shift-based, event-based or limited to critical stages of the port call.
Operating model: attend → observe → measure → record → report → escalate.
Port Operations and Bunker Survey Require Different Controls
These are two separate desks with different inputs, different evidence and different outputs. They are not run from one combined inspection checklist.

Attendance Scope
Six Questions Every Report Must Answer
- What happened?
- When did it happen?
- What caused the exception?
- What evidence exists?
- Who was informed?
- What remains unresolved?
Every Material Event Should Have a Timestamp
Event Categories Recorded
SVC Marine maintains an independent event record for the appointing principal. It is not the official Statement of Facts unless SVC Marine is formally appointed and authorized to issue one.
The agent, terminal, vessel and charter-party parties maintain their own separate official records, and those documents govern where the charter party says so.
Cargoes That Require Closer Field Observation
Cargo Categories
What Is Observed
This is field observation and evidence recording. SVC Marine does not act as a formal cargo warranty surveyor unless specifically appointed for that scope.
Cargo Securing Must Match the Cargo and Voyage
Items Observed During Lashing and Securing
Observation of lashing work is not automatically a formal approval of the vessel’s Cargo Securing Manual, engineering calculation or class-approved sea-fastening design.
When Something Is Damaged During Cargo Operations
- Damage observed
- Time recorded
- Location identified

Vessel Damage Points
Cargo Damage Types
SVC Marine preserves factual evidence. It does not determine legal liability or apportion fault between vessel, stevedore, terminal and cargo interests.
Letters of Protest, notices and claims should be issued or reviewed by the responsible vessel, charterer, cargo party or adviser.
Independent Bunker Quantity Attendance in Vietnam
A bunker survey records the measurable bunker quantity before and after delivery using the agreed tank data, measurement observations and calculation method. It should clearly distinguish survey observations, vessel-provided information and contractual bunker documents.
- Pre-bunker meeting
- Initial ROB
- Tank measurements
- Document review
- Sampling witness
- Delivery monitoring
- Final measurements
- Quantity calculation
- Difference review
- Final evidence and report
Where SVC Marine holds another commercial role in the same transaction, the appointment is described transparently to the principal rather than presented as independent attendance.
Quantity Onboard Before Delivery
Initial ROB Inputs
Status Recorded Per Tank
Corrections and calculation method depend on the vessel’s approved or provided tank tables and the agreed survey procedure.
Missing calibration data is reported as missing. A tank that could not be accessed is never recorded as measured.
During Fuel Delivery
Observations Recorded
SVC Marine attends and records. It does not control vessel safety. The master, chief engineer, bunker supplier and responsible operational parties retain their respective duties throughout the operation.
Sample Identity Must Be Traceable
Records Taken at Sampling
MARPOL-Delivered Sample
Under MARPOL Annex VI regulation 18.8.1 the bunker delivery note is accompanied by a representative sample of the fuel oil delivered. It is retained under the ship’s control until the fuel oil is substantially consumed, and in any case for not less than 12 months from delivery.
IMO sampling guidance is set out in MSC-MEPC.2/Circ.18, which replaced resolution MEPC.182(59).
In-Use / Onboard Samples
Designated sampling points for in-use and onboard fuel oil follow the MARPOL Annex VI amendments in resolution MEPC.324(75), in force from 1 April 2022, with guidance in MEPC.1/Circ.864/Rev.1 and MEPC.1/Circ.889.
These are separate from the delivered sample and serve verification purposes.
Commercial / Supplier Samples
Additional samples retained by the vessel, the supplier or for laboratory testing are contractual rather than regulatory. Their handling depends on the supply contract and company procedure.
Witnessing a sample records how, where and when the sample was drawn and sealed. It does not certify fuel quality.
Fuel quality requires appropriate laboratory testing and contractual or regulatory interpretation. The applicable version of each IMO instrument should be confirmed with the vessel’s flag administration or class.
From Final Sounding to Delivered Quantity
Calculation Inputs
Final ROB − Initial ROB ± Agreed operational adjustments = Observed receipt
This is a concept, not a universal formula. Vessel-specific factors, tank table limitations and the agreed survey procedure change how the figure is derived.
Mass conversion depends on the applicable density and volume-correction inputs. An observed receipt is a survey observation, not a contractually accepted quantity.
What Happens When the Figures Do Not Match?
Possible Discrepancy Sources
Field Response
- Recheck readings where practical
- Recheck tank identification
- Review calculation inputs
- Confirm transfer history
- Compare vessel and barge figures
- Record disagreement
- Preserve evidence
- Inform principal
SVC Marine personnel do not sign away a contractual right and do not accept a shortage on behalf of the owner, master or charterer.
A Letter of Protest is issued by the appropriate authorized vessel or commercial party unless SVC Marine holds explicit written authority.

Contractual valuation and financial settlement depend on the applicable charter party, MOA or agreement. The survey provides the measured figure, not the settlement.
Cargo Readiness Before Operations
Hold and Hatch Observations
Visual condition observation is not a formal hold-cleanliness certification unless SVC Marine is separately appointed for that scope.

Escalated Promptly
Exception reports state facts, timing, evidence and commercial exposure. They do not contain legal conclusions.
Port Captain and Ship Agent Have Different Roles
Ship Agent
Normally handles local agency and port-call formalities.
Port Captain
Represents the appointing principal’s operational interest.
SVC Marine works alongside the nominated ship agent. It does not replace a formally appointed agent unless separately appointed and legally permitted.
Attendance Scope Must Be Defined Before Mobilisation
Appointment Types
A single SVC Marine representative may perform overlapping factual attendance only where competent and agreed. Regulated, certified or specialist surveys are not automatically combined into one appointment.
More Than Remote Reporting
Where corrective action is required during the port call, SVC Marine can mobilise local execution under a separate appointment.
Where the same SVC Marine group is subsequently appointed for corrective work, the observation findings and the commercial execution scope are kept separate and the dual role is disclosed to the principal.

Frequently Asked Questions
What does a port captain do in Vietnam?
A port captain attends vessel and cargo operations for an owner, charterer, operator or cargo interest, records operational events and reports cargo progress, delays, handling issues, damage and other material exceptions.
Can SVC Marine attend loading and discharge?
Yes. Attendance may cover loading, discharge, cargo handling, stowage, lashing observation, stevedore activity, damage and daily reporting.
Can SVC Marine represent a charterer or cargo owner?
Yes, subject to a clearly defined appointment and authority.
Is a port captain the same as a ship agent?
No. The agent handles port-call formalities and local agency matters. A port captain normally represents the appointing principal’s operational interests during cargo activities.
Can SVC Marine provide bunker quantity surveys?
Yes. Appointments may include initial ROB, measurement attendance, sampling records, final ROB, quantity calculation and bunker-survey reporting.
Can SVC Marine perform an on-hire or off-hire bunker survey?
Yes, where the required scope, measurement basis, charter context and vessel access are agreed before attendance.
How is bunker quantity calculated?
The calculation may use vessel tank calibration data, observed sounding or ullage, temperature, density, applicable corrections and initial and final ROB. The exact method depends on vessel data and the agreed survey scope.
Does a bunker survey confirm fuel quality?
No. Quantity survey and sampling attendance do not by themselves certify fuel quality. Laboratory analysis may be required.
Can SVC Marine witness bunker samples?
Yes, where included in the appointment. Sample identity, location, bottle and seal information may be recorded.
What happens if there is a bunker quantity discrepancy?
Measurements and calculation inputs should be reviewed, the discrepancy recorded and the appointing principal informed. Contractual action remains with the responsible vessel and commercial parties.
Can SVC Marine record stevedore damage?
Yes. SVC Marine can record the time, location, visible condition and available photo or video evidence and report the matter to the appointing principal.
Can SVC Marine issue a Letter of Protest?
SVC Marine can help preserve factual evidence, but a Letter of Protest should be issued by the appropriate authorized vessel or commercial party unless SVC Marine has explicit authority.
