The familiar pattern is a ship steaming at full speed to anchor for two days. It burns fuel it did not need to, emits more, and, under the EU ETS and FuelEU Maritime, now pays for both. The IMO’s work on just-in-time arrival describes the alternative: agree a berth time early enough that the ship can adjust its speed. What prevents it is rarely the idea. It is that the ETA, the berth plan and the service bookings live in separate emails and systems that do not update one another.
So AI port operations work starts with data, not models. Predicted arrival from AIS positions and weather, the agent’s messages, the terminal’s berth plan and the pilot and towage schedules combined into one timeline that every party sees, with the uncertainty shown.
