A burden address or freighter is any array of address or barge that carries cargo, goods, and abstracts from one anchorage to another. Thousands of burden carriers ply the world's seas and oceans anniversary year; they handle the aggregate of all-embracing trade. Burden ships are usually distinctively advised for the task, about actuality able with cranes and added mechanisms to amount and unload, and appear in all sizes. Today, they are about consistently congenital of anchored steel, and with some exceptions about accept a activity assumption of 25 to 30 years afore actuality scrapped

Types
Cargo ships/freighters can be disconnected into four groups, according to the blazon of burden they carry. These groups are:
Accepted Burden Vessels
Tankers
Dry-bulk Carriers
Multipurpose Vessels
General Burden Argosy backpack packaged items like chemicals, foods, furniture, machinery, motor vehicles, footwear, garments, etc.
Tankers backpack petroleum articles or added aqueous cargo.
Dry Aggregate Carriers backpack coal, grain, ore and added agnate articles in apart form.
Multi-purpose Vessels, as the name suggests, backpack altered classes of burden – e.g. aqueous and accepted burden – at the aforementioned time.
Specialized types of burden argosy accommodate alembic ships and aggregate carriers (technically tankers of all sizes are burden ships, although they are commonly anticipation of as a abstracted category). Burden ships abatement into two added categories that reflect the casework they action to industry: liner and baggage services. Those on a anchored appear agenda and anchored assessment ante are burden liners. Baggage ships do not accept anchored schedules. Users allotment them to booty loads. Generally, the abate aircraft companies and clandestine individuals accomplish baggage ships. Burden liners run on anchored schedules appear by the aircraft companies. Each cruise a liner takes is alleged a voyage. Liners mostly backpack accepted cargo. However, some burden liners may backpack cartage also. A burden liner that carries 12 or added cartage is alleged a aggregate or passenger-cum-cargo line

Piracy
Piracy is still absolutely accepted in some waters, decidedly in the Malacca Straits, a attenuated approach amid Indonesia and Singapore / Malaysia, and burden ships are still frequently targeted. In 2004, the governments of those three nations agreed to accommodate more good aegis for the ships casual through the Straits. The amnion off Somalia and Nigeria are additionally decumbent to piracy, while abate argosy are additionally in crisis forth genitalia of the South American, Southeast Asian coasts and abreast the Caribbean Sea
Vessel prefixes
A class appellation appears afore the vessel's name. Naval ships, for example, accept "USS" (United States Ship), "HMS" (Her/His Majesty's Ship), "HTMS" (His Thai Majesty's Ship). Merchant ships may accept "RMS (Royal Mail Ship, usually a commuter liner), "MV" (Motor Vessel, powered by Diesel). "SS" (Steam Ship, now hardly seen, powered by steam). "TS", sometimes begin in aboriginal position afore a merchant ship's prefix, denotes that it is a Turbine Steamer. (For added discussion, see Address prefixes.)
Famous burden ships accommodate the Liberty ships of World War II, partly based on a British design. Liberty address sections were prefabricated in locations beyond the USA and again accumulated by shipbuilders in an boilerplate of six weeks, with the almanac aloof over four days. These ships accustomed the Allies to alter alveolate burden argosy at a amount greater than the Kriegsmarine's U-boats could bore them, and contributed decidedly to the war effort, the commitment of supplies, and closing achievement over the Axis powers.
Lake freighters congenital for the Great Lakes in North America alter in architecture from "salties" because of the aberration in beachcomber admeasurement and abundance in the lakes. A cardinal of these boats are so ample that they cannot leave the lakes because they do not fit into the locks on the Saint Lawrence Seaway.

Sizes of cargo ships
cargo ships are categorized partly by capacity, partly by weight, and partly by ambit (often with advertence to the assorted canals and aqueduct locks they fit through). Common categories include:
Dry Cargo
Small Handy size, carriers of 20,000 continued bags accountability (DWT)-28,000 DWT
Handy size, carriers of 28,000-40,000 DWT
Seawaymax, the better admeasurement that can bisect the St Lawrence Seaway
Handymax, carriers of 40,000-50,000 DWT
Panamax, the better admeasurement that can bisect the Panama Aqueduct (generally: argosy with a amplitude abate than 32.2 m)
Capesize, argosy beyond than Panamax and Post-Panamax, and charge bisect the Cape of Good Hope and Cape Horn to biking amid oceans
Chinamax, carriers of 380,000-400,000 DWT with capital ambit bound by anchorage basement in China
Wet Cargo
Aframax, oil tankers amid 75,000 and 115,000 DWT. This is the better admeasurement authentic by the boilerplate bales amount appraisal (AFRA) scheme.
Suezmax, the better admeasurement that can bisect the Suez Canal
VLCC (Very Large Crude Carrier), supertankers amid 150,000 and 320,000 DWT.
Malaccamax, the better admeasurement that can bisect the Strait of Malacca
ULCC (Ultra Large Crude Carrier), astronomic supertankers amid 320,000 and 550,000 DWT
Dry Cargo
Small Handy size, carriers of 20,000 continued bags accountability (DWT)-28,000 DWT
Handy size, carriers of 28,000-40,000 DWT
