The maritime industry has its own language. For someone new to shipping, logistics, vessel operations, or international trade, terms such as berth, bunkering, draft, port call, demurrage, and ship chandling can initially seem confusing.
Understanding common maritime terminology is important for anyone working with vessels, ports, shipping agencies, logistics providers, or marine service companies. These terms are used every day when coordinating vessel arrivals, cargo operations, crew services, supplies, documentation, and other port activities.
This beginner’s guide explains some of the most commonly used maritime terms and shipping terminology in simple language.
A port is a designated coastal or inland facility where ships arrive to load or discharge cargo, embark or disembark passengers, receive supplies, and access maritime services.
Ports may contain container terminals, warehouses, cranes, berths, customs facilities, repair facilities, and other infrastructure required to support vessel operations.
A port call occurs when a vessel visits a port during its voyage.
During a port call, several activities may take place, including cargo loading or unloading, bunkering, crew changes, provision supply, spare parts delivery, fresh water supply, inspections, maintenance, and documentation.
Efficient port call coordination is essential because unnecessary delays can increase vessel operating costs.
A berth is the designated location within a port where a vessel is secured for cargo operations, passenger movements, maintenance, provisioning, or other services.
Berth availability can influence when a vessel is able to enter a port and begin its scheduled operations.
An anchorage is a designated area where vessels can safely anchor while waiting for permission to enter a port, receive services, or continue their voyage.
Some maritime services can also be arranged while vessels remain at anchorage, depending on local regulations, weather conditions, and operational requirements.
A vessel’s draft is the vertical distance between the waterline and the lowest point of its hull.
Draft is particularly important when determining whether a ship can safely enter a port, channel, or berth where water depth may be restricted.
Bunkering refers to supplying fuel to a vessel.
Marine fuel is essential for propulsion systems, generators, and other onboard machinery. Bunkering operations require careful planning, safety procedures, documentation, and coordination between the vessel, supplier, and port authorities.
Ship chandling is the supply of goods and essential materials required by vessels during their voyages.
A ship chandler may provide:
Reliable ship chandling helps vessels maintain adequate supplies without causing unnecessary port delays.
Ship husbandry services cover a broad range of support activities arranged for a vessel during a port call.
These can include crew changes, medical assistance, transportation, hotel arrangements, documentation support, spare parts coordination, cash-to-master arrangements, provisions, and other operational requirements.
A ship agent, also known as a port agent, represents the ship owner, operator, charterer, or manager while the vessel is calling at a particular port.
The agent coordinates with port authorities, customs, immigration, terminals, suppliers, transport providers, and other parties to help ensure smooth vessel operations.
A crew change is the process of replacing seafarers who have completed their contracts with crew members joining the vessel.
Crew change coordination may involve immigration procedures, airport transfers, accommodation, transportation, medical arrangements, documentation, and communication with the vessel.
These abbreviations are frequently used in maritime communication.
ETA – Estimated Time of Arrival
The expected time a vessel will arrive at a port or designated location.
ETD – Estimated Time of Departure
The expected time a vessel will depart from a port.
ATA – Actual Time of Arrival
The actual recorded time when the vessel arrives.
Learning basic maritime terminology makes it easier to understand how vessels, ports, shipping agents, and marine service providers work together.
