A liner service in merchant shipping is a shipping service that operates to a timed schedule visiting a fixed loop of ports and operated by one or more ships.
A liner service is one of the two main classifications of merchant shipping, the other being tramp shipping. [1] The service is expected to be regular, scheduled, repeated and published. [1] From once established the frequency is generally expected to be no more than monthly, the actual frequency depending on the business available. [1]
The development of liner services, both cargo liners, and passenger liners, seems to have developed from the 1850s with the increasing adoption of steam power to attain more regular scheduled services. [2]
Whereas up until 1956 cargo liners relied upon gears to handle variable sided loads, from about 1956 containers and cellular ships began soon after, with the increasing dominance of the container ship for trade. [3]
Maritime transport or more generally waterborne transport, is the transport of people (passengers) or goods (cargo) via waterways. Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air or ground, but significantly slower for longer distances. Maritime transport accounts for roughly 80% of international trade, according to UNCTAD in 2020.
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for paddle steamer or "SS" for screw steamer. As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for motor vessel, so it is not correct to use "SS" for most modern vessels.
A container ship is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo.
Mitsui O.S.K. Lines is a Japanese transport company headquartered in Toranomon, Minato, Tokyo, Japan. It is one of the largest shipping companies in the world.
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes.
A boat or ship engaged in the tramp trade is one which does not have a fixed schedule, itinerary nor published ports of call, and trades on the spot market as opposed to freight liners. A steamship engaged in the tramp trade is sometimes called a tramp steamer; similar terms, such as tramp freighter and tramper, are also used. Chartering is done chiefly on London, New York, and Singapore shipbroking exchanges. The Baltic Exchange serves as a type of stock market index for the trade.

A trunk deck ship is a type of merchant ship with a hull that was stepped inward in order to obtain more favourable treatment under canal toll rules then in effect. As those tolls were set by net tonnage, a measure of volume, and as the tonnage rules did not account for all of the cargo space of such vessels, trunk deck ships incurred lower tolls than more conventional ships of equivalent capacity. When the measurement rules were changed, the type was no longer built.
A cargo liner, also known as a passenger-cargo ship or passenger-cargoman, is a type of merchant ship which carries general cargo and often passengers. They became common just after the middle of the 19th century, and eventually gave way to container ships and other more specialized carriers in the latter half of the 20th century.
