Within the intricate framework of global maritime logistics, the ship agent’s function extends far beyond being a simple intermediary. As a ship agency with over 60 years of experience providing ship agency services in Spain, we understand the vital importance of this role for the global shipping sector.
What is a ship agent?
Definition and overview
According to the IMO FAL Convention (effective January 2018), a ship agent is defined as:
“The party representing the ship’s owner and/or charterer (the Principal) in port. If so instructed, the agent is responsible to the Principal for arranging, together with the port, a berth, all relevant port and husbandry services, tending to the requirements of the Master and crew, clearing the ship with the port and other authorities (including preparation and submission of appropriate documentation) along with releasing or receiving cargo on behalf of the Principal.”
In practice, an agent maritime (as commonly referred to in international shipping circles) can act for any of the parties involved in the voyage and in any capacity as agreed between the agent and their principal. The ship agent serves as the local representative, providing critical local knowledge while ensuring that the principal’s requirements are performed with the utmost efficiency.
Why are ship agents important?
Ship agents constitute a fundamental link in maritime trade for several reasons:
- Local expertise: They provide invaluable knowledge about procedures and regulations.
- Central coordination: They function as the conduit for all information between vessel and shore.
- Cost optimization: Their efficient management minimizes stays and optimizes resources.
- Problem solving: Their ability to anticipate and resolve incidents avoids costly delays.
- Risk reduction: Their knowledge protects the shipowner from possible sanctions.
- Operational continuity: Ship agency services guarantee fluid operations.
Main roles and responsibilities of a ship agent

Understanding what is the role of a ship agent requires examining their key responsibilities. Functioning as the de facto “port single window,” the ship agent is the conduit for all information exchanged between the vessel and shore. In fact, a ship agent may coordinate over 130 distinct operations throughout a vessel’s port stay — a clear indication of the complexity nature of their role.
Cargo operations and documentation
The ship agent is responsible for supervising the loading and unloading of cargo, ensuring that everything runs efficiently and according to plan. This includes organizing cargo handling operations and handling the necessary paperwork. Among their tasks are processing cargo manifests, preparing and submitting customs documents, and ensuring compliance with all health and phytosanitary regulations.
Port coordination and logistics
Well before the vessel arrives, the ship agent is already working behind the scenes to make sure everything is ready. This involves requesting pilots and tugboats, securing a berth allocation, and coordinating the docking. The agent also acts as a link with the different port authorities and manages complementary land transport and any special equipment the vessel might need.
Support services and crew assistance
The agent’s role also covers essential support services for both the vessel and its crew. This includes organizing emergency repairs, coordinating crew changes, and managing medical assistance when required. They also handle immigration procedures, visa formalities, fuel supply coordination (bunkering), and ensure waste disposal is done following environmental regulations.
Financial and administrative management
Financial management is a key part of the ship agent’s responsibilities. They manage the advance of funds to cover port expenses, settle accounts for each port call, and handle payments to local suppliers. Additionally, they focus on controlling costs, optimizing expenses, and keeping all stakeholders informed through real-time progress reports.
Types of ship agents
When defining what is a ship agent, it’s important to recognize the variety of specialized roles:
Port agents
The port agent is central to all trades, responsible for organizing all aspects of the port call. At Ibérica Marítima, this is our core ship agency service. We provide assistance in over 110 ports, managing every detail with precision: from berth allocation and coordination with port authorities to customs clearance and operational reporting. Our experienced team and direct presence in key locations ensure maximum reliability and efficiency.
Cargo agents
Operating primarily in liner and break bulk trades, cargo agents are responsible for securing cargo for the line or ship operator. They maintain contact with local shippers and provide information on vessel schedules and rates. At Ibérica Marítima, cargo operations include agency services both for shipowners (OPA) and for charterers or cargo owners (CPA), closely monitoring all operations throughout the port call. Our services cover full and protective agency roles, bunker call and technical agency support, cargo documents management, single point of contact (SPOC) coordination, draft surveys, certificates management, and slops removal.
Owners’ or charterers’ agents
Depending on circumstances, there may be more than one ship agent attending the vessel. One party may appoint their own independent representative to protect their specific interests. These are known as owners’ or charterers’ agents: professionals who act exclusively on behalf of the shipowner or the charterer, respectively, ensuring their commercial, operational, or legal interests are safeguarded during the port call.
Other specialized agents
The sector also includes agents appointed for specific circumstances such as emergency port calls, pollution incidents, or specialized services like crew management. At Ibérica Marítima, we also provide comprehensive husbandry services, acting as a trusted extension of the shipowner’s team. We ensure tailored support that keeps port calls short and efficient. These services include crew change and immigration requirements, cash to master, spare parts logistics, medical attendance, supplies delivery, and offshore supply coordination.
Delegated authority and legal responsibilities
Acting “as agents only”
Agents maritime always act under the formula “as agents only,” which delimits their legal responsibility. This means they don’t assume personal responsibility for the principal’s obligations. Also, their responsibility is limited to correctly executing instructions received. Finally, they must clearly identify themselves as agents in all communications.
Obligations and remuneration
The ship agent maintains a fiduciary relationship with the principal, which means they are bound by duties of loyalty, transparency, and good faith. This trust-based connection is essential for ensuring smooth collaboration and reliable service. As for remuneration, it can vary depending on the agreement. In some cases, it takes the form of a fixed fee per port call. In others, it may be based on specific service components, calculated as a percentage of the freight, or structured as a combination of these models.
Evolution and future of the ship agent profession

The role of the ship agent has undergone a remarkable transformation, shifting from that of a simple intermediary to a strategic consultant with a high level of specialization and technical expertise. This evolution has been largely driven by digitalization, which has introduced a range of new tools and systems that have reshaped the profession. Among the most impactful changes are the implementation of electronic customs clearance systems, the use of port information exchange platforms, and the adoption of real-time tracking technologies. Additionally, the automation of documentary processes has streamlined operations and increased efficiency across the board.
Looking ahead, the ship agent profession will continue to evolve in response to emerging technologies and global challenges. Agents will need to adapt to the integration of blockchain platforms for documentation, comply with increasingly stringent environmental regulations, and address the growing concerns around maritime cybersecurity. Moreover, the management and oversight of autonomous vessels will become a critical area of focus, demanding new skills and innovative approaches within the sector.
At Ibérica Marítima, with over six decades of experience as maritime agents, we know that a great ship agent can make the difference between a seamless, profitable port call and a challenging one.
