([Hellenic Shipping News](https://www.hellenicshippingnews.com/a-complete-guide-to-port-calls/)) - **Who: Who handles the port call on the ground?** The ship agent, who acts as the local representative coordinating authorities, terminal, crew and suppliers, according to Hellenic Shipping News. ([Hellenic Shipping News](https://www.hellenicshippingnews.com/a-complete-guide-to-port-calls/)) - **Where: Where did a recent casualty require a port of refuge?** Off South Africa, where the HMM containership HMM Platinum was approaching a port of refuge after a container fire, The Maritime Executive reported in October 2026. ([The Maritime Executive](https://maritime-executive.com/article/hmm-containership-heading-to-port-of-refuge-due-to-container-fire)) - **When: When did that casualty response take place?** The Maritime Executive reported in October 2026 that the vessel was displaying a restricted manoeuvrability message on its AIS transmission while heading to the port of refuge. ([The Maritime Executive](https://maritime-executive.com/article/hmm-containership-heading-to-port-of-refuge-due-to-container-fire)) - **Why: Why does port information exchange matter?** A 2021 study in Transportation Research Procedia describes port information systems as a single window for trade, similar in function to airport information systems. ([Transportation research procedia (Elsevier BV)](https://doi.org/10.1016/j.trpro.2021.02.146)) - **How: How is vessel traffic in ports being made more predictable?** A 2020 study in IEEE Access applied an improved fuzzy neural network to forecast vessel traffic volume, noting that accurate prediction helps rational scheduling of port resources and reduces vessel accidents. ([IEEE Access](https://doi.org/10.1109/access.2020.2982904)) Port agents arrange everything a vessel needs between arrival and departure: berth bookings, customs and immigration clearance, crew movements, cash to master, supplier coordination and the paperwork that lets cargo move. The agent is the owner's or charterer's local representative at that port, and its clock starts well before the ship arrives. According to [Hellenic Shipping News](https://www.hellenicshippingnews.com/a-complete-guide-to-port-calls/) (October 2026), a port call is a berth booking to a port authority, a service opportunity to a ship agent and a data point to a commodity analyst. Those three views run on the same ETA. ## What does a port agent do before the vessel arrives? The agent files the pre-arrival paperwork and books the services the ship will need on the berth. Most of the work is done while the vessel is still at sea. - Lodge pre-arrival notices with customs, immigration, health and the port authority. - Book the berth and confirm the ETA (estimated time of arrival) with the terminal and the master. - Order pilots and tugs, and line up launch boats for crew and visitors. - Collect the ship's particulars, certificates and crew list, and check them against the port's requirements. - Prepare the PDA (pro forma disbursement account, the agent's estimate of port costs sent to the owner before the call). Port information systems increasingly carry this exchange. A 2021 study in Transportation Research Procedia on the Port of Hamburg ecosystem describes port information systems as a single window for trade, similar in function to airport information systems ([Elsevier](https://doi.org/10.1016/j.trpro.2021.02.146)). ## What happens on the day of the call? On arrival the agent becomes the ship's fixer on the ground, moving between the vessel, the terminal, the authorities and every supplier with a delivery to make. 1. Attend the vessel with customs and immigration officers for clearance. 2. Deliver the cash to master and collect signed documents from the master. 3. Coordinate chandlers, bunker barges, fresh water, spare parts and repair teams so each one reaches the ship inside the berth window. 4. Arrange crew changes, medical attendance and shore leave transport. 5. Report progress to the owner, the charterer and the DOC holder (the company named on the ship's Document of Compliance, accountable for its safety management). Timing is the agent's real product. When a berth window opens early or slips, the agent is the person who tells the chandler whether the stores truck should leave now, a problem covered in [same-day quoting when a berth window opens](https://vesselreach.si/blog/same-day-quoting-when-a-berth-window-opens). ## What does the agent do at a port of refuge or casualty? A casualty turns the agent into the ship's local crisis manager, often with no notice and no commercial plan. The HMM containership HMM Platinum was displaying a restricted manoeuvrability message on its AIS transmission while approaching South Africa to reach a port of refuge after a container fire, [The Maritime Executive](https://maritime-executive.com/article/hmm-containership-heading-to-port-of-refuge-due-to-container-fire) reported in October 2026. In that situation the agent coordinates with the harbour master on a safe berth, books firefighting and salvage support, arranges surveyors and class attendance, handles immigration for a crew that never planned to be there, and keeps the P&I club (the mutual insurer covering third-party liability, including casualty response) and the owner informed. Every supplier brought in is a cost the agent must document, because the casualty file usually ends in a general average or insurance claim. ## How does the agent work with chandlers, bunker suppliers and yards? The agent is the gatekeeper for supplier access to the vessel, and the supplier's paperwork flows through the agent's office. Three practical points matter. - **Access:** the agent arranges the launch or gate pass that gets a technician or delivery driver to the ship. - **Documents:** delivery receipts, bunker delivery notes and repair reports are collected by the agent and passed to the master for signature. - **Payment:** the agent often settles local supplier invoices against the owner's disbursement account, so the supplier is paid by the agent rather than the owner. That payment chain carries risk. [PDA fraud and bank detail change scams](https://vesselreach.si/blog/pda-fraud-and-bank-detail-change-scams-how-port-suppliers-verify-a-payment-reque) target exactly this step, which is why verification matters before any invoice is settled. ## Where does digitalisation fit? Connectivity and port data are reshaping how agents and their suppliers coordinate. Speedcast and Soya IT Marine Solutions completed the deployment of upgraded digital connectivity on 41 roll-on/roll-off vessels for Wallenius Wilhelmsen, [Hellenic Shipping News](https://www.hellenicshippingnews.com/soya-it-marine-solutions-selects-speedcast-to-deliver-connectivity-services-supporting-fleetwide-digital-enablement-project-for-wallenius-wilhelmsen/) reported in October 2026. Reliable ship-to-shore links mean the agent can confirm a berth or a stores delivery with the master in minutes rather than by satellite call. Port traffic itself is becoming more predictable. A 2020 study in IEEE Access used an improved fuzzy neural network to forecast vessel traffic volume in a Chinese port, with the authors noting that accurate prediction helps rational scheduling of port resources and reduces vessel accidents ([IEEE Access](https://doi.org/10.1109/access.2020.2982904)). For an agent, that is the difference between staffing for a known surge and reacting to one. The wider maritime IoT picture is still patchy. A 2021 survey in the IEEE Internet of Things Journal found that a large performance loss is often inevitable when 4G, 5G or satellite technologies are used directly on the ocean, so hybrid satellite-terrestrial networks are needed ([IEEE Internet of Things Journal](https://doi.org/10.1109/jiot.2021.3056091)). Agents and suppliers who plan for a dropped connection still win the day. ## What does this mean for suppliers selling at the port call? If the agent controls access, documents and payment, then the agent is a sales channel as much as a customer. Suppliers who know which agency handles a given vessel's call can reach the right desk before the ship berths. That is where vessel-arrival data earns its keep. A 2019 study in IEEE Access combined artificial intelligence with an agent-based architecture to simulate port traffic flow, building a framework on an Internet of Things structure to improve the realism of the simulation ([IEEE Access](https://doi.org/10.1109/access.2019.2943654)). The same principle applies commercially: the earlier you see the vessel, the earlier you can call the agent. For a supplier, the practical routine is to map each arriving vessel to its owner or manager, identify the [port agency](https://vesselreach.si/blog/how-port-agents-win-new-clients-from-vessel-arrivals) handling the call, and open the conversation with a specific service and a realistic delivery window. Our guide to [port call patterns and forecasting marine service demand](https://vesselreach.si/blog/port-call-patterns-forecasting-marine-service-demand) sets out how to read those patterns port by port. ## How VesselReach helps VesselReach, built by CatalystIQ, turns vessel movements at your target ports into conversations with the companies and people behind them, including the agencies and managers who decide supplier access. - **Vessel intelligence:** see vessels near your ports and scheduled arrivals, which means you can approach the agent before the berth window opens. - **AI company targeting and decision-maker discovery:** the platform identifies the relevant company behind each vessel and finds roles such as operations, fleet, procurement and managing directors, which means your outreach reaches the desk that books the service. - **Multichannel outreach with automated follow-ups:** staged email, WhatsApp and phone contact, with AI answering routine enquiries and escalating to your team when it cannot answer reliably.

Port agents act as the owner's or charterer's local representative: they file pre-arrival notices, book the berth, order pilots and tugs, clear the vessel with customs and immigration, arrange crew changes, coordinate suppliers and settle local disbursements against the pro forma disbursement account. ([Hellenic Shipping News](https://www.hellenicshippingnews.com/a-complete-guide-to-port-calls/)) ### What is the agent's role when a ship needs a port of refuge? The agent coordinates a safe berth with the harbour master, books firefighting or salvage support, arranges surveyors and class attendance, handles immigration for the crew and documents every cost for the casualty file. The Maritime Executive reported the HMM Platinum heading to a South African port of refuge after a container fire in October 2026. ([The Maritime Executive](https://maritime-executive.com/article/hmm-containership-heading-to-port-of-refuge-due-to-container-fire)) ### Do suppliers get paid by the port agent or by the shipowner? Often by the agent. Local supplier invoices are commonly settled through the owner's disbursement account handled by the agent, which is why suppliers should verify bank details and payment instructions before releasing goods or services. ### How can a chandler find out which agent is handling a vessel? Start from the vessel's arrival data and ownership records, then confirm the agency with the terminal or the ship manager. Contacting the agent before the berth window opens gives the supplier time to quote and plan delivery. ### Why does connectivity matter to port agents and suppliers? Reliable ship-to-shore links let the agent confirm berths, deliveries and crew movements quickly.

[A complete guide to port calls](https://www.hellenicshippingnews.com/a-complete-guide-to-port-calls/), Hellenic Shipping News, 2026-10-16 ## More on this topic Port agents are the local hands for a vessel's call. They file pre-arrival notices, book the berth, order pilots and tugs, clear the ship with customs and immigration, arrange crew changes and coordinate every supplier that comes alongside. They also prepare the pro forma disbursement account and often settle local invoices. When a ship diverts after a casualty, the agent books the refuge berth and documents the costs. If you ask what do port agents do, the short answer is that they carry the paperwork and the timing that let a supplier deliver and get paid. --- VesselReach, built by CatalystIQ.
