Wave-class Tanker
The Wave-class tankers are a class of fast fleet tankers in service with the Royal Fleet Auxiliary. The class is tasked with providing fuel, food, fresh water, ammunition and other supplies to Royal Navy vessels around the world. There are two ships in the class, and . The ships were ordered to replace the aging s and . The two vessels have seen service in a number of locations, including anti-drug and hurricane relief operations in the Caribbean Sea, anti-piracy activities around the Horn of Africa, and deterrent patrols in the South Atlantic. As of early 2022, both ships were earmarked for "extended readiness" status (i.e. uncrewed reserve). History A contract was placed for the vessels in 1997 with Vickers Shipbuilding and Engineering Ltd (Marconi Marine VSEL). Construction of ''Wave Knight'' began in 1998 at VSEL's Barrow-in-Furness yard and the ship was launched in 2000. With the acquisition of Marconi Electronic Systems and its Marconi Marine subsidiary in 1999 Briti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Portsmouth Based Type 23 Frigate, HMS Iron Duke Carrying Out Replenishment At Sea (RAS) With RFA Wave Ruler, Whilst Carrying Out The Duties Of The Atlantic Patrol Task (North) ATP (N)
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Vickers Shipbuilding And Engineering Ltd
Vickers Shipbuilding and Engineering, Ltd (VSEL) was a shipbuilding company based at Barrow-in-Furness, Cumbria in northwest England that built warships, civilian ships, submarines and armaments. The company was historically the Naval Construction Works of Vickers Armstrongs and has a heritage of building large naval warships and armaments. Through a complicated history the company's shipbuilding division is now BAE Systems Submarine Solutions and the armaments division is now part of BAE Systems Land & Armaments. History The company was founded in 1871 by James Ramsden as the Iron Shipbuilding Company, but its name was soon changed to Barrow Shipbuilding Company. In 1897, ''Vickers & Sons'' bought the ''Barrow Shipbuilding Company'' and its subsidiary the ''Maxim Nordenfelt Guns and Ammunition Company'', becoming ''Vickers, Sons and Maxim, Limited''. The shipyard at Barrow became the Naval Construction & Armaments Company. In 1911 the company was renamed ''Vickers Ltd'', and ...

Double Hull
A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks. The space between the two hulls is sometimes used for storage of ballast water. Double hulls are a more extensive safety measure than double bottoms, which have two hull layers only in the bottom of the ship but not the sides. In low-energy collisions, double hulls can prevent flooding beyond the penetrated compartment. In high-energy collisions, however, the distance to the inner hull is not sufficient and the inner compartment is penetrated as well. Double hulls or double bottoms have been required in all passenger ships for decades as part of the Safety Of Life At Sea or SOLAS Convention. Uses Double hulls ...

Reverse-osmosis
Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules, e.g., water, H2O) to pass freely. In the normal osmosis process, the solvent natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dracone Barge
A Dracone Barge is a large flexible watertight tube intended to carry a liquid cargo while towed mostly-submerged behind a ship. One large current example of the type has a capacity of 935 cubic metres (4.23m diameter, 91m long) while weighing only 6.5 tonnes empty. The Dracone Barge was invented in 1956 by Professor William Hawthorne as a new type of oil tanker. The intent was to create an improved transport technology: the long tube can be pulled by a lower powered vessel than the equivalent tanker, the cargo can be handed off at the destination very quickly, and incurs no drag cost when empty (because it can easily be taken aboard), as compared to the similar unladen to laden drag of the rigid-hulled tanker of equivalent capacity. The daytime signal (known as a day shape) for dracone is a diamond shape at or near the aftermost extremity of the last vessel or object being towed and if the length of the tow exceeds 200 meters an additional diamond shape where it can best be seen ...

Underway Replenishment
Replenishment at sea (RAS) (North Atlantic Treaty Organization/Commonwealth of Nations) or underway replenishment (UNREP) (U.S. Navy) is a method of transferring fuel, munitions, and stores from one ship to another while under way. First developed in the early 20th century it was used extensively by the United States Navy as a logistics support technique in the Pacific theatre of World War II, permitting U.S. carrier task forces to remain at sea indefinitely. History Concept Prior to underway replenishment, coaling stations were the only way to refuel ships far from home. The Royal Navy had an unparalleled global logistics network of coaling stations and the world's largest collier fleet. This capability allowed the Navy to project naval power around the world and far from home ports. This had two disadvantages: the infrastructure was vulnerable to disruption or attack, and its use introduced a predictable pattern to naval operations that an enemy could exploit. Early attempts ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Clyde
The River Clyde ( gd, Abhainn Chluaidh, , sco, Clyde Watter, or ) is a river that flows into the Firth of Clyde in Scotland. It is the ninth-longest river in the United Kingdom, and the third-longest in Scotland. It runs through the major city of Glasgow. Historically, it was important to the British Empire because of its role in shipbuilding and trade. To the Romans, it was , and in the early medieval Cumbric language, it was known as or . It was central to the Kingdom of Strathclyde (). Etymology The exact etymology of the river's name is unclear, though it is known that the name is ancient: It was called or by the Britons and by the Romans. It is therefore likely that the name comes from a Celtic language—most likely Old British. But there is more than one old Celtic word that the river's name could plausibly derive from. One possible root is the Common Brittonic , meaning 'loud' or 'loudly'. More likely, the river was named after a local Celtic goddess, '' Clōta ...

Govan
Govan ( ; Cumbric?: ''Gwovan'?''; Scots: ''Gouan''; Scottish Gaelic: ''Baile a' Ghobhainn'') is a district, parish, and former burgh now part of south-west City of Glasgow, Scotland. It is situated west of Glasgow city centre, on the south bank of the River Clyde, opposite the mouth of the River Kelvin and the district of Partick. Historically it was part of the County of Lanark. In the early medieval period, the site of the present Govan Old churchyard was established as a Christian centre for the Brittonic Kingdom of Alt Clut (Dumbarton Rock) and its successor realm, the Kingdom of Strathclyde. This latter kingdom, established in the aftermath of the Viking siege and capture of Alt Clut by Vikings from Dublin in AD 870, created the sandstone sculptures known today as the Govan Stones. Govan was the site of a ford and later a ferry which linked the area with Partick for seasonal cattle drovers. In the eighteenth and nineteenth centuries, textile mills and coal mining were ...
