Tug
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 harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines.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 t ...

Salvage Tug
A salvage tug, also known 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 numbers 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 * ...

Articulated Vehicle
An articulated vehicle is a vehicle which has a permanent or semi-permanent coupling in its construction. This coupling works as a large pivot joint, allowing it to bend and turn more sharply. There are many kinds, from heavy equipment to Articulated bus, buses, trams and Articulated car, trains. Articulated locomotive, Steam locomotives were sometimes articulated so the driving wheels could pivot around corners. In a broader sense, any vehicle towing a Trailer (vehicle), trailer (including a semi-trailer) could be described as articulated (which comes from the Latin word ''articulus'', "small joint"). In the UK, an ''articulated lorry'' is the combination of a Tractor unit, tractor and a trailer, abbreviated to "artic". In the US, it is called a semi-trailer truck, tractor-trailer or semi-truck and is not necessarily considered articulated. Types Buses Buses are articulated to allow for a much longer bus that can still navigate within the turning radius of a normal bus. Mo ...

Log Raft
Timber rafting is a method of transporting felled tree trunks by tying them together to make rafts, which are then drifted or pulled downriver, or across a lake or other body of water. It is arguably, after log driving, the second cheapest means of transporting felled timber. Both methods may be referred to as timber floating. The tradition of timber rafting cultivated in Austria, the Czech Republic, Germany, Latvia, Poland and Spain was inscribed on UNESCO Representative List of the Intangible Cultural Heritage of Humanity in 2022 Historical rafting Unlike log driving, which was a dangerous task of floating separate logs, floaters or raftsmen could enjoy relative comfort of navigation, with cabins built on rafts, steering by means of oars and possibility to make stops. On the other hand, rafting requires wider waterflows. Timber rafts were also used as a means of transportation of people and goods, both raw materials ( ore, fur, game) and man-made.

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. Gases are kept refrigerated onboard the ships to enable safe carriage in liquid and vapour form and for this reason, gas carriers usually have onboard refrigeration systems. Design and construction of all gas carriers operating internationally is regulated by the International Maritime Organization through the International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk. There are various types of gas carriers, depending on the type of gas carried and the type of containment system, two of the most common being the Moss Type B (spherical) type and the membrane (typically GTT) type. 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 convert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 War. ''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 ...
