Port Captain / Ship Agent

What is a port agent?

A port agent, or ship agent, is the local representative appointed to handle a vessel’s affairs while it is in port: arranging the berth, clearing the ship with the authorities, liaising with the terminal over cargo, and settling the port costs for the appointing principal.

The port agent is the principal’s hands and eyes at a port the principal is rarely present in. A bulk carrier may call at a load port the owner has never visited, governed by local pilotage rules, customs procedures and terminal practices that only a resident party can navigate. The agent is appointed to be that resident party. FONASBA, the Federation of National Associations of Ship Brokers and Agents, defines the ship’s agent as the party who acts on behalf of the shipowner or charterer in a port to handle all matters connected with the ship’s call, and its standard agency agreements set out the duties, the authority and the indemnities that govern the relationship. The agent does not own or charter the ship and takes no position in the freight; the agent provides a service for a fee plus the disbursements they advance on the principal’s behalf.

The role matters most where money and time are recorded. The same agent who books the pilot also relays the master’s notice of readiness and countersigns the statement of facts that the laytime account is later reconciled against. Whose agent does that work, and on whose instructions, is the question that runs through the rest of this page.

What a port agent does during a call

The agent’s brief runs from before arrival to after departure. The standard scope on a dry-bulk call covers:

• Pre-arrival. Apply for the berth, lodge the pre-arrival documents with customs, immigration and the port authority, book the pilot, tugs and linesmen, and confirm the terminal’s readiness to work the cargo.
• Arrival and readiness. Receive the master’s notice of readiness and pass it to the charterer or receiver in the form and within the hours the charter party requires, then record arrival, anchoring and berthing times.
• Cargo operations. Liaise with the terminal and stevedores, monitor loading or discharge against the agreed rate, and keep the running record of times, stoppages and weather that becomes the statement of facts.
• Documentation. Arrange and present the bill of lading for the master’s or owner’s release, handle cargo manifests, and assemble the document set the fixture and the authorities require.
• Husbandry. Order bunkers, fresh water, stores and provisions, arrange crew changes, medical attention and any repairs, and deal with off-signers and on-signers.
• Disbursements and departure. Advance the port costs (pilotage, towage, berth dues, agency fee), settle them locally, obtain outward clearance, and render the disbursement account back to the principal afterwards.

The single thread through all of this is that the agent acts on instructions and within the authority granted by whoever appointed them. ITIC, the International Transport Intermediaries Club, which insures ship agents against professional liability, repeatedly flags that an agent who exceeds that authority, or acts where the principal is unclear, carries the loss personally. The practical discipline is to know, on every call, exactly who the principal is and what the principal has authorised.

Owner’s agent, charterer’s agent, and protecting agent

On most bulk fixtures more than one agent is in play at a single port, because the owner and the charterer have different interests to protect and the charter party decides who nominates whom. The allocation matrix below sets out how the three roles divide the work on a representative voyage charter fixed on FIO terms, where the charterer controls and pays for cargo operations.

The nomination clause in the charter party is what drives this split. When the charterer “nominates agents at load and discharge”, the agent who runs the call answers to the charterer, even though the agent is handling the owner’s ship. Owners protect themselves by appointing a protecting agent (sometimes called a supervisory or husbandry agent in this watching role) whose only job is to safeguard the owner’s position on the matters that decide the laytime and demurrage account: that the NOR is validly tendered, that the statement of facts is accurate, and that nothing in the cargo operation prejudices the owner’s freight or claims.

Types of shipping agent

The labels describe the function and the appointing party, not different professions. One firm may act in any of these capacities on different calls. The enumeration below sets out the family.

Agent type	Acts for	Typical scope	Who pays
Owner's agent	The shipowner	Full attendance on the ship: berth, NOR, documents, disbursements, husbandry, clearance	The owner
Charterer's agent	The charterer or receiver	Cargo and terminal liaison, NOR receipt, statement of facts, charterer-side costs; runs the call where the charter nominates them	The charterer
Protecting agent	The owner, on a charterer-nominated call	Watching brief over NOR, laytime evidence and the statement of facts to protect the owner's interest	The owner who appoints them
Husbandry agent	The shipowner or manager	Crew, stores, bunkers, spares, repairs and welfare only, separate from the cargo and commercial call	The owner or manager
General / liner agent	A line or operator across many calls	Standing appointment covering all the line's ships into a port, common in liner trades and less so in tramp bulk	The line or operator

The husbandry agent and the protecting agent are the two most commonly confused. A husbandry agent handles the ship’s domestic needs, the crew and the stores, and may be appointed even where the commercial call is run by someone else. A protecting agent exists specifically because someone else, usually the charterer, is running the commercial call, and the owner wants an independent eye on the events that feed the money. The general or liner agent is mainly a liner-trade construct; in tramp dry bulk the appointment is usually call-by-call rather than standing.

Port agent versus ship broker and freight forwarder

The port agent sits among several intermediaries that a cargo touches, and the roles are easy to blur because each acts “on behalf of” someone. They are distinct in who they serve and at what point in the deal.

Role	Acts for	Where in the deal	What they do not do
Port agent	The ship's owner or charterer, at one port	After the fixture, while the ship is in port	Does not negotiate the fixture or take freight risk
Ship broker	Owner or charterer, in the market	Before the fixture, matching ship to cargo	Does not attend the ship in port or handle cargo
Freight forwarder	The cargo owner / shipper	Across the whole cargo journey, often multimodal	Does not represent the ship or settle the ship's port costs
Port captain / supercargo	Owner, charterer or cargo interest	On the quay, during cargo operations	Is not the appointed legal agent of the ship in the port

The search term “port captain” deserves its own line. In dry-bulk usage a port captain is usually a port-side superintendent or supercargo: an experienced mariner placed on the quay to oversee the cargo operation itself, the loading sequence, the stowage and trim, the draft survey and the condition of the cargo, on behalf of whoever sent them. That is a cargo-operations supervisory role, distinct from the appointed ship’s agent, who is the legal representative handling the ship’s clearance, documents and disbursements. The two often work the same call and are sometimes the same firm, but a port captain who only supervises cargo is not, by that fact, the ship’s agent. A ship broker works the market before the fixture and disappears once the ship is fixed; the port agent only appears after it.

Common confusions about port agents

The recurring failure modes are about who appoints whom and whose interest the agent owes, not about what the agent physically does.

• “The owner’s ship, so the owner’s agent.” Not necessarily. Under an FIO voyage charter the charter party frequently lets the charterer nominate the load and discharge agent. That agent handles the owner’s ship but answers to the charterer, which is precisely why owners appoint a protecting agent.
• The agent owes both sides equally. An agent owes duties to the party that appointed and pays them. A charterer-nominated agent is the charterer’s agent, even while attending the owner’s vessel. ITIC’s guidance to its members stresses that acting outside the appointing principal’s authority, or treating a counterparty’s interests as if they were the principal’s, is a frequent source of liability claims.
• Time charter flips the default. The allocation changes with the charter type. On a voyage charter the owner runs the voyage and typically appoints agents unless the charter shifts that to the charterer. On a time charter the charterer directs the ship’s employment and routinely appoints the agents at the ports the ship is ordered to, with the owner still able to appoint a protecting agent.
• The agent guarantees the NOR. The agent relays the master’s notice of readiness; the master tenders it and the charter party decides whether it is valid. A misdated or wrongly addressed NOR passed on by the agent does not become valid because the agent handled it, and the laytime consequences fall on the owner, not the agent.
• Disbursements are the agent’s cost. The disbursement account is the principal’s cost, advanced by the agent and reimbursed. FONASBA’s standard agreements provide for an advance against estimated disbursements precisely so the agent is not financing the principal’s port costs out of the agency fee.

A single port call: who appoints whom

This is the pattern the rest of the page generalises: one ship, one port, two principals with different stakes, and an agency arrangement drawn so each side has its interest covered without either holding the other’s pen.

Scope and what this page does not cover

This page explains the port agent (ship agent) as a commercial role in a bulk port call: what the agent does, how the owner’s agent, charterer’s agent, protecting agent and husbandry agent differ, who appoints and pays whom under common charter types, and how the role differs from a ship broker, a freight forwarder and a port captain or supercargo. It does not draft or interpret a specific agency agreement, opine on an agent’s liability under a given jurisdiction’s law, set agency fees or disbursement levels for any port, or resolve a contested statement of facts or notice of readiness. Those are matters for the appointed agent, the desk’s operations team and, where liability is in issue, the agent’s professional indemnity insurers, working from the actual charter party, the agency agreement and the signed port documents. The worked example here is representative and anonymised, not a record of any real call.
