A plain-language guide to the systems and concepts shaping smarter ports.
Digital TwinA digital representation of a physical environment
A digital model connected to information about a physical environment or process. In a port, it can combine spatial context with operational information to support understanding and analysis.
In practice View a terminal layout alongside available equipment or vessel information. A 3D model alone does not establish a live operational connection.

Software used to plan, coordinate and record the movement and storage of cargo within a terminal.
In practice Managing container inventory and coordinating berth, yard and gate activities.

A shipboard system that automatically exchanges vessel identity, position and other information with ships and coastal authorities.
In practice Providing vessel-position context for a port view. AIS data availability and quality need to be considered for each use.

The predicted time at which a vessel or vehicle will arrive at a specified location. It is an estimate and can change as conditions change.
In practice An ETA for a pilot boarding place differs from an ETA at a berth. State the location and time zone when sharing it.

A standard unit of container capacity based on a twenty-foot container. A forty-foot container generally represents two TEUs.
In practice TEU is used to describe ship capacity or container throughput; it is not a weight unit.

A driverless vehicle used to move containers within a defined terminal operating environment.
In practice Transporting a container between the quayside and the container yard.

Connected physical devices and sensors that collect and exchange data about equipment or environmental conditions.
In practice A sensor on port infrastructure can provide measurements for monitoring and maintenance planning.

A named or numbered location where a vessel can moor or anchor. In terminal operations, the berth is where ship-side activities are planned.
In practice A berth plan coordinates a vessel’s expected occupation of that location.

The exchange and agreement of arrival and departure expectations between a shipping line and a terminal.
In practice Updating a berthing window as the voyage or terminal plan changes.
