3200 Horse Power Class Tug
The Duhast class tug is a little known class of naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN), and this 3200-horsepower tug has received NATO reporting name Duhast class. Built by Wuhu Xinlian Shipbuilding Co., Ltd. (芜湖新联造船有限公司), formerly Wuhu Shipyard, since 2004, the name of this class is taken from the installed power of the vessels, with the exact type designation still remaining unknown. After the first pair was built, as of the mid-2010s, a total of twelve of this class have been confirmed as being in active service. The 3200-horsepower class series ships in PLAN service are designated by a combination of two Chinese characters followed by three-digit number. The second Chinese character is Tuo (拖), meaning tug in Chinese, because these ships are classified as tugboats. The first Chinese character denotes which fleet the ship is service with, with East (Dong, 东) for East Sea Fleet, North (Bei, 北) for North Se ...

Length Overall
Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often reported. T ...

Waterline Length
A vessel's length at the waterline (abbreviated to L.W.L) is the length of a ship or boat at the level where it sits in the water (the ''waterline''). The LWL will be shorter than the length of the boat overall (''length overall'' or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more loaded, it will sit lower in the water and its ambient waterline length may change; but the registered L.W.L is measured from a default load condition. Measurement This measure is significant in determining several of a vessel's properties, such as how much water it displaces, where the bow and stern waves occur, hull speed, amount of bottom-paint needed, etc. Traditionally, a stripe called the "boot top" is painted around the hull just above the waterline. In sailing boats, longer waterline length will usually enable a greater maximum speed, because it allows greater sail area, without increasing beam or draft. Greater beam and draft ...

Auxiliary Ship
An auxiliary ship is a naval ship designed to support combatant ships and other naval operations. Auxiliary ships are not primary combatant vessels, though they may have some limited combat capacity, usually for purposes of self-defense. Auxiliary ships are extremely important for navy, navies of all sizes because if they were not present the primary fleet vessels would be unsupported. Thus, virtually every navy maintains an extensive fleet of auxiliary ships, however, the composition and size of these auxiliary fleets vary depending on the nature of each navy and its primary mission. Smaller coastal navies tend to have smaller auxiliary vessels focusing primarily on littoral and training support roles, while larger blue-water navy, blue-water navies tend to have larger auxiliary fleets comprising longer-range fleet support vessels designed to provide support far beyond territorial waters. Roles Replenishment One of the most direct ways that auxiliary ships support the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Liberation Army Navy

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 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 ...

NATO Reporting Name
NATO uses a system of code names, called reporting names, to denote military aircraft and other equipment used by post-Soviet states, former Warsaw Pact countries, China, and other countries. The system assists military communications by providing short, one- or two-syllable names, as alternatives to the precise proper names, which may be easily confused under operational conditions or are unknown in the Western world. The assignment of reporting names is managed by the Five Eyes Air Force Interoperability Council (AFIC), previously known as the Air Standardization Coordinating Committee (ASCC), which is separate from NATO. Based in Washington DC, AFIC comprises representatives from the militaries of three NATO members (Canada, the United Kingdom and United States) and two non-NATO countries (Australia and New Zealand). When the system was introduced in the 1950s, reporting names also implicitly designated potentially hostile aircraft. However, since the end of the Cold War, ...

East Sea Fleet
The Eastern Theater Command Navy (东部战区海军, ETCN) is a formation of China's People's Liberation Army Navy (PLAN) and the naval component of the Eastern Theater Command. The ETCN was reorganized from the East Sea Fleet (ESF) by 2016. Currently Wang Zhongcai is the commander of the ESF and Mei Wen it's political commissar. History The PLAN was formed toward the end of the Chinese Civil War. In March 1949, Zhang Aiping of the Third Field Army was ordered by the Central Military Commission (CMC) of the Chinese Communist Party to create a naval force from the field army. Zhang's only previous naval experience was organizing an irregular riverine force near Hongze Lake in 1941 and leading it in a successful campaign against local bandits. The PLAN was created on 21 April when Zhang established the East China Military Region Navy, or East China Navy (ECN), with a thirteen-member headquarters, and he was formally appointed by the CMC as the ECN's commander and commissar ...

North Sea Fleet
The North Sea Fleet (NSF; ), concurrently the Northern Theater Command Navy (), is one of the three fleets of China's People's Liberation Army Navy. Headquartered in Qingdao, Shandong, the fleet provides naval forces to the Northern Theater Command. In September 1950, the Qingdao Army Base was redesignated as a naval base. Following the departure of the Soviet Navy from Lüshunkou (Port Arthur), the North Sea Fleet was established in 1960 with naval bases in Qingdao and Lüshunkou. The fleet currently includes China's first aircraft carrier, ''Chinese aircraft carrier Liaoning, Liaoning'', as well as nuclear-powered attack and missile submarines. The North Sea Fleet was historically the most capable of the Navy's three fleets, being the first in China to operate destroyers, shore-based missiles and nuclear submarines. In recent years however, the shift in strengthening of importance and strategic capabilities of the East Sea Fleet, East and South Sea Fleet, South Sea Fleets are ...

South Sea Fleet
The Southern Theater Command Navy (STCN), or the South Sea Fleet (SSF) until 2018, is a formation of China's People's Liberation Army Navy (PLAN) and the naval component of the Southern Theater Command. History In December 1949, the Fourth Field Army transferred personnel from the 15th Army to create the Guangdong Military Region Riverine Defense Command. The Riverine Defense Command commanded the Wanshan Archipelago Campaign in May to August 1950 and was the "nucleus" of the South Central China Military Region Navy created by the Fourth Field Army in December 1950. The military region's navy became the PLAN's South Sea Fleet in 1955. The SSF won the Battle of the Paracel Islands against South Vietnam in 1974. China's first anti-piracy patrol to Somalia deployed from the SSF in December 2008. Components STCN headquarters is at Zhanjiang, with bases in Sanya and Guangzhou. The bases at Sanya include Yulin Naval Base and Longpo Naval Base, the latter for submarines. It con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
