Indeed, until recently virtually all ocean liners were able to transport mail, package freight and express, and other cargo in addition to passenger luggage, and were equipped with cargo holds and derricks, kingposts, or other cargo-handling gear for that purpose. The type does however include many classes of ships which are designed to transport substantial numbers of passengers as well as freight. The category does not include cargo vessels which have accommodations for limited numbers of passengers, such as the formerly ubiquitous twelve-passenger freighters in which the transport of passengers is secondary to the carriage of freight. See Braer, Erika, Exxon Valdez, Prestige and Torrey Canyon for examples of tankers that have been involved in oil spills.Ī passenger ship is a ship whose primary function is to carry passengers.

But even with their deadweight of 441,585 metric tons, sailing as VLCC most of the time, they do not use more than 70% of their total capacity.Īpart from pipeline transport, tankers are the only method for transporting large quantities of oil, although such tankers have caused large environmental disasters when sinking close to coastal regions, causing oil spills. Today's largest oil tankers in comparison by gross tonnage are TI Europe, TI Asia, TI Oceania, which are the largest sailing vessels today.

The use of such large ships is in fact very unprofitable, due to the inability to operate them at full cargo capacity hence, the production of supertankers has currently ceased. It has a deadweight of 565,000 metric tons and length of about 458 meters (1,500 ft).

chemicals, such as ammonia, chlorine, and styrene monomerĭifferent products require different handling and transport, thus special types of tankers have been built, such as chemical tankers, oil tankers, and gas carriers.Īmong oil tankers, supertankers were designed for carrying oil around the Horn of Africa from the Middle East the FSO Knock Nevis being the largest vessel in the world, a ULCC supertanker formerly known as Jahre Viking (Seawise Giant).

hydrocarbon products such as oil, LPG, and LNG.

A wide range of products are carried by tankers, including: Tankers can range in size from several hundred tons, designed to serve small harbours and coastal settlements, to several hundred thousand tons, with these being designed for long-range haulage. ĭuring wars, merchant ships may be used as auxiliaries to the navies of their respective countries, and are called upon to deliver military personnel and materiel.Ī tanker is a ship designed to transport liquids in bulk. Today, the Greek fleet accounts for some 16 per cent of the world's tonnage this makes it currently the largest single international merchant fleet in the world, albeit not the largest in history. The Greek merchant marine is the largest in the world. Many merchant ships operate under a ' flag of convenience' from a country other than the home of the vessel's owners, such as Liberia and Panama, which have more favorable maritime laws than other countries. They come in myriad sizes and shapes, from six-metre (20 ft) inflatable dive boats in Hawaii, to 5,000-passenger casino vessels on the Mississippi River, to tugboats plying New York Harbor, to 300-metre (1,000 ft) oil tankers and container ships at major ports, to passenger-carrying submarines in the Caribbean. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes.
