Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness ...

Salvage Tug
A salvage tug, known also historically as a wrecking tug, is a specialized type of tugboat that is used to rescue ships that are in distress or in danger of sinking, or to salvage ships that have already sunk or run aground. Overview Few tugboats have ever been truly fully dedicated to salvage work; most of the time, salvage tugs operate towing barges, platforms, ships, or performing other utility tugboat work. Tugs fitted out for salvage are found in small quantities around the globe, with higher concentrations near areas with both heavy shipping traffic and hazardous weather conditions. Salvage tugs are used by specialized crew experienced in salvage operations (salvors). Their particular equipment includes: * extensive towing provisions and extra tow lines/cables, with provisions for towing from both bow and stern and at irregular angles * extra cranes * firefighting gear ** deluge systems ** hoses ** nozzles * mechanical equipment such as: ** common mechanical repair parts ...

USS Tawasa (ATF-92)
USS ''Tawasa'' (AT-92) was a constructed for the United States Navy during World War II. Her purpose was to aid ships, usually by towing, on the high seas or in combat or post-combat areas, plus "other duties as assigned." She served in the Pacific Ocean and had a very successful career marked by the winning of three battle stars during World War II, two during the Korean War, and seven campaign stars during the Vietnam crisis. ''Tawasa'' was laid down on 22 June 1942 at Portland, Oregon, by the Commercial Iron Works; launched on 22 February 1943; sponsored by Mrs. Thomas F. Sullivan, mother of the five Sullivan brothers; and commissioned on 17 July 1943. World War II Pacific Theatre operations ''Tawasa'' held her shakedown cruise off the lower California coast in late August and returned to Portland. The tug steamed to San Pedro, California, in October and departed there on the 20th for Hawaii, towing two fuel oil barges. She arrived at Pearl Harbor on 4 November and was ass ...

Ship
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and ...

Gas Tanker
A gas carrier, gas tanker, LPG carrier, or LPG tanker is a ship designed to transport LPG, LNG, CNG, or liquefied chemical gases in bulk. Types Fully pressurized gas carrier The seaborne transport of liquefied gases began in 1934 when a major international company put two combined oil/LPG tankers into operation. The ships, basically oil tankers, had been converted by fitting small, riveted, pressure vessels for the carriage of LPG into cargo tank spaces. This enabled transport over long distances of substantial volumes of an oil refinery by-product that had distinct advantages as a domestic and commercial fuel. LPG is not only odourless and non-toxic, it also has a high calorific value and a low sulphur content, making it very clean and efficient when being burnt. Today, most fully pressurised oceangoing LPG carriers are fitted with two or three horizontal, cylindrical or spherical cargo tanks and have typical capacities between 20,000 and 90,000 cubic meters and Length over ...
