([The Loadstar](https://theloadstar.com/detention-fees-have-a-simple-problem-a-bigger-bill-cannot-move-a-box-that-cannot-move/)) - **How: How do automated terminals handle container flows?** A 2021 study in IEEE Transactions on Automation Science and Engineering modelled container flows through quay cranes, yard cranes and automated guided vehicles, finding that congestion and unbalanced task assignment affect terminal capacity. ([IEEE Transactions on Automation Science and Engineering](https://doi.org/10.1109/tase.2021.3085329)) Container terminal billing is moving from manual yard events to connected operating systems that automate charges and reduce revenue leakage. That shift matters to maritime service providers because every disputed terminal charge is a port call where someone must produce documents, explain costs and keep the vessel on schedule. According to [Marine Insight](https://www.marineinsight.com/what-a-container-actually-costs-you-inside-the-terminals-cost-puzzle/?utm_source=rss&utm_medium=rss&utm_campaign=what-a-container-actually-costs-you-inside-the-terminals-cost-puzzle) (November 2026), connected terminal operating systems such as iTOMS automate container billing, eliminate revenue leakage and support Federal Maritime Commission compliance across yard events. The same week, the FMC confirmed it will host a demurrage and detention research symposium on 31 March 2027 in Washington, D.C., according to [MarineLink](https://www.marinelink.com/news/fmc-host-demurrage-detention-research-544087) (November 2026). ## What changed in terminal billing Terminal charges are increasingly calculated from recorded yard events rather than negotiated after the fact. A connected terminal operating system logs each move, lift and storage day, then bills from that record. For a port agent (the local representative who handles a ship's business at a port), that means the terminal's version of events becomes the default version. The commercial pressure runs both ways. [The Loadstar](https://theloadstar.com/detention-fees-have-a-simple-problem-a-bigger-bill-cannot-move-a-box-that-cannot-move/) (November 2026) reports that the FMC wants research into when charges above compensatory cost actually speed cargo movement, and that shippers must distinguish a delay they can prevent from one they cannot. A bigger detention bill cannot move a box that cannot move. ## Why demurrage and detention disputes reach the supplier Demurrage (charges for holding a container inside the terminal beyond free time) and detention (charges for keeping the box outside the terminal beyond free time) are usually argued between carrier and shipper. The supplier enters when the dispute turns on what happened at the port: when the vessel berthed, when cargo was ready, when a repair or survey delayed departure. - Chandlers may be asked to prove delivery times for stores that affected loading. - Agents hold the port call timeline, including ETA (estimated time of arrival) changes and berth windows. - Repair yards document off-hire periods that explain why a vessel missed a cargo window. Each of those records can decide whether a charge stands. A supplier who can produce a timestamped delivery note or a berth confirmation is more useful to the customer than one who cannot. ## Terminal automation raises the bar for documentation Automated terminals generate more data, not less argument. A 2021 study in [IEEE Transactions on Automation Science and Engineering](https://doi.org/10.1109/tase.2021.3085329) modelled container flows through quay cranes, yard cranes and automated guided vehicles, and found that traffic congestion, unbalanced task assignment and batch arrival affect terminal capacity. When capacity tightens, delays become measurable and chargeable. Security of terminal software matters too. A 2020 study in [IEEE Access](https://doi.org/10.1109/access.2020.3008395) assessed maritime container terminal software systems and identified vulnerabilities that leave port systems open to cyber-attack. A terminal that cannot bill accurately because its system is disrupted creates disputes that reach the agent's desk. ## The wider cost context for port service providers Terminal charges sit inside a larger cost debate. According to [Marine Insight](https://www.marineinsight.com/shipping-emissions-cost-the-global-economy-963-billion-between-1990-to-2020-new-study-finds/?utm_source=rss&utm_medium=rss&utm_campaign=shipping-emissions-cost-the-global-economy-963-billion-between-1990-to-2020-new-study-finds) (November 2026), shipping emissions cost the global economy USD 963 billion between 1990 and 2020, with damages potentially exceeding the cost of decarbonisation. Operators facing that pressure scrutinise every port cost, including terminal handling and the service charges around it. New terminal capacity also changes where those costs land. [Offshore Energy](https://www.offshore-energy.biz/2026/11/05/excelerate-and-axdo-strike-multi-year-bahamas-lng-deal-for-caribbeans-new-terminal) (November 2026) reports that Excelerate Energy and AxDo Bahamas signed an 11-year LNG supply agreement for a new offshore hub near Grand Bahama. New hubs create new port calls, new agency appointments and new supplier lists to get onto. ## What chandlers, agents and yards should do now 1. Keep a timestamped record of every delivery, survey and repair that touches a vessel's schedule. 2. Ask the agent for the berth window and any ETA change before quoting a delivery time. 3. Put the record in a form the customer can forward to a carrier or the FMC process. 4. Track terminal billing changes at the ports you serve, because the terminal's record becomes the default. The FMC symposium in March 2027 will produce research that carriers, shippers and terminals will cite. Suppliers who already hold clean records will be easier to defend and easier to rebook.

Container terminal billing is the process of charging for yard events such as lifts, storage days and container moves. Connected terminal operating systems now automate those charges from recorded events, according to Marine Insight (November 2026). ([Marine Insight](https://www.marineinsight.com/what-a-container-actually-costs-you-inside-the-terminals-cost-puzzle/?utm_source=rss&utm_medium=rss&utm_campaign=what-a-container-actually-costs-you-inside-the-terminals-cost-puzzle)) ### Why is the FMC researching demurrage and detention? The Federal Maritime Commission wants research into when charges above compensatory cost actually speed cargo movement, according to The Loadstar (November 2026). The FMC will host a research symposium on 31 March 2027 in Washington, D.C., per MarineLink. ([The Loadstar](https://theloadstar.com/detention-fees-have-a-simple-problem-a-bigger-bill-cannot-move-a-box-that-cannot-move/)) ### How can a port agent help with a terminal charge dispute? A port agent holds the port call timeline, including ETA changes and berth windows. That record can show whether a delay was preventable, which is the distinction The Loadstar reports the FMC research is examining. ([The Loadstar](https://theloadstar.com/detention-fees-have-a-simple-problem-a-bigger-bill-cannot-move-a-box-that-cannot-move/)) ### What records should a ship chandler keep for terminal disputes? Keep timestamped delivery notes, survey times and repair records that touch the vessel schedule. Those records let the customer show when stores arrived and whether a delay was within anyone's control. ### How does terminal automation affect service providers? Automated terminals record more yard events, so billing follows the terminal's data. A 2021 study in IEEE Transactions on Automation Science and Engineering found congestion and unbalanced task assignment affect terminal capacity, which can turn delays into chargeable events.

Marine Insight reports that connected terminal systems automate billing and support FMC compliance, while the FMC is funding research into demurrage and detention charges. For chandlers, agents and repair yards, the practical answer is to keep timestamped records of deliveries, surveys and repairs, because those records decide whether a terminal charge stands. VesselReach helps maritime businesses find the right operations and procurement contacts before the ETA changes. Terminal charges now come from recorded yard events, so the terminal's log is the version a port agent must answer to. Marine Insight reports that connected terminal operating systems automate container billing and support Federal Maritime Commission compliance, and MarineLink reports the Commission's demurrage and detention research symposium in Washington, D.C. on 31 March 2027. Chandlers, agents and ship repair yards hold the timestamps that decide a dispute: delivery notes, berth windows, estimated time of arrival changes and off-hire periods. VesselReach, built by CatalystIQ, is an AI-powered maritime sales intelligence and outreach platform that shows expected arrivals at your ports and finds operations and procurement contacts by role. --- VesselReach, built by CatalystIQ.
