When working with ocean freight and maritime transport, it is important to know and understand the difference between Liner and Tramp.
These terms are used to designate a type of ocean transport service and can also be used to designate how a vessel is currently operating.
What is LINER service ?
This term designates a service which operates a regular route, on a regular basis. The ports, which are called by a vessel operating on a liner service route, and the schedule call dates are known ahead of time and often publicly available.
A Liner service is generally characterized by:
- A set schedule and route (ports of call)
- Mainly used for containerized and standard size goods
- Cargo is booked on a specific route and voyage
- Vessels are typically container vessels, general purpose vessels or RO/RO (roll on, roll off) vessels.
What is TRAMP service ?
On the other hand, vessels which operate on the Tramp market – commonly called trampers – do not operate on a regular route or schedule and are made available for clients who will charter – or part-charter (with other clients) – the vessel for a specific journey or a specific duration.
A TRAMP service is generally characterized by:
- No set schedule or route (ports of call).
- Mainly used for bulk cargo (iron ore, coal, grain, oil…) and oversized goods.
- Vessel is chartered on a full or partial basis and route is set in function of charterers.
- Vessels are typically general purpose vessels, bulk carriers, tankers and some RO/RO vessels.
