Understanding maritime analytics requires familiarity with technical terms ranging from AIS data transmission to vessel classification systems.
No records found.
A (7 terms)
AIS is a vessel tracking system that transmits real-time information such as position, speed, course, and vessel identity via VHF radio signals. It is widely used for collision avoidance, fleet monitoring, and maritime situational awareness.
The geographic area where AIS signals are received by satellites or terrestrial base stations.
A data packet transmitted by AIS containing vessel position, identity and navigation information.dio signals. It is widely used for collision avoidance, fleet monitoring, and maritime situational awareness.
A device used to receive AIS signals from vessels.
The onboard unit installed on vessels that sends and receives AIS signals.
A designated location where vessels can safely anchor while waiting to enter port or load cargo.

B (5 terms)
A shore-based AIS receiver station that captures vessel transmissions.
The width of a vessel at its widest point.
A specific location in a port where a vessel docks to load or unload cargo or passengers.
The forward front section of a vessel.
A vessel designed to transport unpackaged bulk cargo such as coal, grain, or iron ore.
C (7 terms)
A unique radio identifier assigned to a vessel for maritime communication.
The aim is to reduce the carbon intensity of international shipping by 40% by 2030, compared to 2008 levels. CIIs apply to ships of 5,000GT and above engaged in international trade. CII is calculated from a vessel’s annual emissions, capacity and distance travelled. Ships are ranked A (major superior), B (minor superior), C (moderate), DContinue reading “Carbon Intensity Indicator (CII)”
The maximum amount of cargo a ship can carry.
A vessel designed primarily for transporting goods.
A cargo vessel designed to carry standardised shipping containers.
The intended direction a vessel plans to travel.
The actual direction a vessel is moving across the Earth’s surface, measured in degrees.
D (4 terms)
The total weight a ship can safely carry including cargo, fuel, water, crew and provisions.
The port where a vessel begins its voyage.
The port entered by a vessel’s crew into the AIS system indicating where the ship is headed.
The vertical distance between the waterline and the bottom of the vessel’s hull.
E (2 terms)
The expected time when a vessel will reach its destination port.
The estimated time when a vessel will leave a port.
F (2 terms)
The country where a vessel is registered and whose laws the ship follows.
A group of vessels owned or operated by the same company or organisation.
G (3 terms)
The use of GPS or RFID technology to create a virtual geographic boundary, enabling software to trigger a response when a mobile device enters or leaves a particular area.
Satellite navigation systems used to determine vessel location, including GPS, Galileo, and GLONASS.
A measurement of the internal volume of a ship used for regulatory purposes.
H (1 terms)
The direction the bow of a vessel is pointing, measured in degrees.
I (1 terms)
A unique identification number assigned to ships by the International Maritime Organisation (IMO). It remains constant throughout the vessel’s lifetime.
M (2 terms)
The process of observing vessel movements using AIS or satellite systems.
A nine-digit number used to uniquely identify vessels and maritime radio stations.
R (1 terms)
A wireless, non-contact technology that uses radio waves to transfer data enabling automatic identification and tracking of vessels.
S (1 terms)
AIS signals captured by satellites instead of terrestrial receivers, allowing tracking in remote ocean areas.
T (2 terms)
Enables real-time vessel tracking by receiving AIS signals via coastal base stations, typically within a 50 nautical mile radius. Provides high-frequency, low-latency updates for maritime safety, port traffic management and coastal security.
A radio device that transmits AIS messages containing vessel data.
V (1 terms)
The process of monitoring ship movements using AIS and satellite systems.
X (1 terms)
A radar frequency commonly used for short-range vessel navigation.
Z (1 terms)
Another term for Coordinated Universal Time (UTC), commonly used in maritime communication.
