A port captain is a representative who attends the port on behalf of the owner or charterer, plans the vessel's cargo operation, coordinates between ship and terminal and follows up that the operation proceeds efficiently and safely. The role centres on the vessel's time in port and on carrying out the operation plan.
What is Port Captain Services?
A port captain ensures that decisions directly affecting the vessel's time in port and operational efficiency are followed up on site. Carrying out the loading plan, coordinating the work programme with the terminal and liaising with the master are the core parts of the role.
Before the vessel arrives, the port captain reviews the cargo list, pre-stowage plan, port constraints such as draft, berth length and equipment, and the terminal's working pattern. Potential bottlenecks can then be identified and shared with the parties before operations begin.
During the operation, the port captain acts as the link between the ship's officers, the stevedores, terminal planning and the agent. The port captain follows hatch sequence, gang allocation and the stowage plan on site and, where the plan needs to change, coordinates updates with the principal's approval.
The role provides on-site decision support to owners and charterers, particularly for project cargo, mixed general cargo or operations with a tight schedule. Which stages are covered is agreed at the quotation stage.
Why does it matter?
Every additional hour a vessel spends in port is a direct cost to the owner and charterer. Managing the operation to plan on site helps reduce waiting and unproductive working time.
Carrying out the stowage plan correctly on site matters for meeting the vessel's trim and stability requirements, avoiding restows at discharge ports and reducing the risk of cargo damage.
Time and event records kept throughout the operation allow comparison with the statement of facts and give the principal independent data on matters such as laytime or off-hire.
Who is it for?
- Shipowners who want on-site representation in port
- Charterers who want to follow operation time and efficiency closely
- Project logistics companies planning complex cargo operations
- Ship operators without their own staff in the port
- Operators on multi-port voyages who need the stowage plan maintained
Scope of service
- Pre-arrival review of the operation plan, cargo list and pre-stowage plan
- Assessment of port and terminal constraints (draft, berth, equipment, working hours)
- Coordination between vessel, terminal, agent and stevedores
- Follow-up of the loading / stowage plan on site
- Follow-up of hatch sequence and gang allocation
- Liaison with the master on trim and draft requirements
- Recording of operation time, stoppages and their causes
- Daily status reports to the principal
The exact scope is agreed at the quotation stage according to the nature of the operation.
Key checkpoints
- 01Plan versus execution
- The approved stowage plan is compared with what is actually loaded in each hold; where deviations are found, a correction is worked out with the vessel and terminal.
- 02Operation rate
- Gang numbers, equipment use and hatch sequence are followed, and bottlenecks slowing the operation are recorded with their causes.
- 03Vessel constraints
- The master's trim, draft and stability requirements and the hold and deck load limits are kept in view throughout the operation.
- 04Stoppages
- Weather, equipment, waiting for cargo and terminal-related stoppages are logged with start and end times, and their causes noted for allocating responsibility.
- 05Information flow
- The port captain makes sure information flows promptly between the vessel, terminal and principal, and that decisions are confirmed in writing.
How does the process work?
- 01
Pre-planning
Vessel particulars, the cargo plan and port conditions are assessed and an operation programme is drawn up.
- 02
Arrival coordination
Before berthing, the work programme and hatch sequence are agreed with the terminal and agent.
- 03
Managing the operation
The plan is followed throughout the operation, issues are resolved with the parties concerned and the principal is kept regularly informed.
- 04
Close-out report
Operation time, events and outcomes are reported to the principal.
Information we need from you
- Owner or charterer details and scope of authority
- Vessel particulars, cargo list and pre-stowage plan
- Port, terminal and agent details

Report content and format are agreed according to your request.
Key terms
- Stevedore
- The port worker or company that physically carries out the loading and discharging of vessels.
- Gang
- A team of stevedores working together at one hatch or handling point; the operation rate depends largely on the number of gangs.
- Restow
- Moving cargo from one position on board to another, or discharging and reloading it; usually an extra cost arising from stowage planning errors.
- Off-hire
- Under a time charter, a period during which the vessel cannot perform for reasons specified in the contract and hire ceases to be payable.
Frequently asked questions
What does a port captain do?
A port captain plans and follows the operation in port on behalf of the owner or charterer and coordinates between the vessel, terminal and agent.
What is the difference between a port captain and a supercargo?
A port captain usually manages the vessel's port operation on behalf of the owner or charterer. A supercargo follows up that cargo-related instructions are carried out on behalf of the cargo owner or charterer. The exact duties can vary with the contract.
How long does a port captain assignment last?
It usually covers the period from the vessel's arrival to departure; a pre-planning phase can be added if required.
Does the port captain make decisions in place of the master?
No. Decisions on ship safety, stability and navigation rest with the master. The port captain coordinates the principal's operational requirements with the master, terminal and agent.
Does the port captain prepare the stowage plan?
The stowage plan is usually prepared by the vessel, the charterer or the line's planning department. The port captain reviews it, assesses its feasibility against port conditions and follows its execution on site; any need for plan preparation is discussed separately at the quotation stage.
