Sea transport systems in today's shipping market have evolved into three separate but closely connected segments: bulk shipping, liner shipping and specialized shipping. Although these segments belong to the same industry, each carries out different tasks and has a very different character. It is the mode with the largest movement of goods or people.
Large homogeneous parcels such as iron ore, coal and grain are carried by the bulk shipping industry, small parcels of general cargo are carried by the liner shipping industry and specialised cargoes shipped in large volumes are transported by the specialized shipping industry. These three cargo streams create demand for bulk transport, liner transport and specialized transport. A major distinction is drawn between the fleets of ships owned by companies moving their own cargo in their own ships and the ships owned by independent shipowners and chartered to the cargo owners.
The bulk shipping industry carries large parcels of raw materials and bulky semi-manufactures. This is a very distinctive business. Bulk vessels handle few transactions, typically completing about six voyages with a single cargo each year, so the average revenue depends on a dozen of negotiations per ship each year. In addition, service levels are usually low so little overhead is required to run the ships and organize the cargo.
The liner service transports small parcels of general cargo, which includes manufactured and semi-manufactured goods and many small quantities of bulk commodities. Because there are so many parcels to handle on each voyage, this is an organization-intensive business. In addition, the transport leg forms part of an integrated production operation, so speed, reliability and high service levels are important. With so many transactions the business relies on published prices, though nowadays the prices are negotiated with major customers as part of service agreement.
Specialized shipping services transport difficult cargoes of which the five most important are cars, forest product, refrigerated cargo, chemicals and liquified gas. These trades fall somewhere between bulk and liner. Service provides in these trades invest in specialized ships and offer higher service levels than bulk shipping.
The three segments of the shipping industry all carry cargo in ships but they face different tasks in terms of the value and volume of cargo, the number of transactions handled and the commercial systems employed. [1]
Freight transport, also referred as freight forwarding, is the physical process of transporting commodities and merchandise goods and cargo. The term shipping originally referred to transport by sea but in American English, it has been extended to refer to transport by land or air as well. "Logistics", a term borrowed from the military environment, is also used in the same sense. Here more goods or passenger are transported than other modes of transport.
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.
Containerization is a system of intermodal freight transport using intermodal containers. Containerization, also referred as container stuffing or container loading, is the process of unitization of cargoes in exports. Containerization is the predominant form of unitization of export cargoes, as opposed to other systems such as the barge system or palletization. The containers have standardized dimensions. They can be loaded and unloaded, stacked, transported efficiently over long distances, and transferred from one mode of transport to another—container ships, rail transport flatcars, and semi-trailer trucks—without being opened. The handling system is mechanized so that all handling is done with cranes and special forklift trucks. All containers are numbered and tracked using computerized systems.
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories.
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.
In transportation, freight refers to goods conveyed by land, water or air, while cargo refers specifically to freight when conveyed via water or air. In economics, freight refers to goods transported at a freight rate for commercial gain. The term cargo is also used in case of goods in the cold-chain, because the perishable inventory is always in transit towards a final end-use, even when it is held in cold storage or other similar climate-controlled facilities, including warehouses.
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 distribution center for a set of products is a warehouse or other specialized building, often with refrigeration or air conditioning, which is stocked with products (goods) to be redistributed to retailers, to wholesalers, or directly to consumers. A distribution center is a principal part, the order processing element, of the entire order fulfillment process. Distribution centers are usually thought of as being demand driven. A distribution center can also be called a warehouse, a DC, a fulfillment center, a cross-dock facility, a bulk break center, and a package handling center. The name by which the distribution center is known is commonly based on the purpose of the operation. For example, a "retail distribution center" normally distributes goods to retail stores, an "order fulfillment center" commonly distributes goods directly to consumers, and a cross-dock facility stores little or no product but distributes goods to other destinations.
Shipbroking is a financial service, which forms part of the global shipping industry. Shipbrokers are specialist intermediaries/negotiators between shipowners and charterers who use ships to transport cargo, or between buyers and sellers of vessels.
A freight rate is a price at which a certain cargo is delivered from one point to another. The price depends on the form of the cargo, the mode of transport, the weight of the cargo, and the distance to the delivery destination. Many shipping services, especially air carriers, use dimensional weight for calculating the price, which takes into account both weight and volume of the cargo.
Less-than-truckload shipping or less than load (LTL) is the transportation of an amount of freight sized between individual parcels and full truckloads. Parcel carriers handle small packages and freight that can be broken down into units less than approximately 150 pounds (68 kg). Full truckload carriers move entire semi-trailers. Semi-trailers are typically between 26 and 53 feet and require a substantial amount of freight to make such transportation economical. The term LTL can refer to the freight itself, or to the carrier that transports the such freight.
A freight forwarder or forwarding agent is a person or a company who co-ordinates and organizes the movement of shipments on behalf of a shipper by liaising with carriers. The carriers may use a variety of shipping modes, including ships, airplanes, trucks, and railroads, and often use multiple modes for a single shipment. A freight forwarder does not move the goods but acts as an agent in the logistics network and will carry out freight consolidation, rate negotiations, shipment tracking, customs and other documentation, among other tasks. FIATA describes a freight forwarder as the "Architect of transport".
A shipping line or shipping company is a company whose line of business is ownership and operation of ships.
In shipping, break-bulk, breakbulk, or break bulk cargo, also called general cargo, is goods that are stowed on board ships in individually counted units. Traditionally, the large numbers of items are recorded on distinct bills of lading that list them by different commodities. This is in contrast to cargo stowed in modern intermodal containers as well as bulk cargo, which goes directly, unpackaged and in large quantities, into a ship's hold(s), measured by volume or weight.
A shipping container is a container with strength suitable to withstand shipment, storage, and handling. Shipping containers range from large reusable steel boxes used for intermodal shipments to the ubiquitous corrugated boxes. In the context of international shipping trade, "container" or "shipping container" is virtually synonymous with "intermodal freight container", a container designed to be moved from one mode of transport to another without unloading and reloading.
The international shipping industry can be divided into four closely related shipping markets, each trading in a different commodity: the freight market, the sale and purchase market, the newbuilding market and the demolition market. These four markets are linked by cash flow and push the market traders in the direction they want.
A shipping agency, shipping agent, or ship agency is the term used to refer to the appointed companies that handle operational and procedural (legal) requirements for a commercial vessel's call at a port for the purposes of cargo handling (loading/discharging), emergency calls, repairs, crew changes, or ship demolition, and protect the general interests of their principals on behalf of ship owners, disponent owners, or charterers in an objective manner.
