Diana-class Patrol Vessel
The ''Diana'' class, also known as the Minor Standard Craft Mk II, are a class of six patrol boats in service with the Royal Danish Navy. Built by Faaborg Værft A/S, the ships displace and have a maximum speed of knots. The class was intended to replace the aging ''Barsø'' class of patrol boats. The lead ship of the class, , entered Danish service in 2007. The ''Diana''-class vessels were initially tasked with fisheries protection, patrol and search and rescue but are currently tasked with international and combat operations. Design and description The ''Diana'' class, also known as the Minor Standard Craft Mk II, are a series of patrol vessels constructed of glass reinforced plastic. They measure long with a beam of and a draught of . They are powered by two MTU 16V396 TB94 diesel engines turning two shafts with controllable pitch propellers creating . This gives the patrol vessels a maximum speed of . The ships mount two machine guns and have a complement of 9, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Ship
The lead ship, name ship, or class leader is the first of a series or class of ships all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take as many as five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in the class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost-effective than building prototypes, and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to the lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following ...

Glass Reinforced Plastic
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patrol Boat Classes
A patrol is commonly a group of personnel, such as law enforcement officers, military personnel, or security personnel, that are assigned to monitor or secure a specific geographic area. Etymology From French ''patrouiller'', from Old French ''patouiller'' “to paddle, paw about, patrol”, from ''patte'' “a paw”. Military In military tactics, a ''patrol'' is a sub-subunit or small tactical formation, sent out from a military organization by land, sea or air for the purpose of combat, reconnaissance, or a combination of both. The basic task of a patrol is to follow a known route with the purpose of investigating some feature of interest or, in the assignment of a ''fighting patrol'' (U.S. ''combat patrol''), to find and engage the enemy. A patrol can also mean a small cavalry or armoured unit, subordinate to a troop or platoon, usually comprising a section or squad of mounted troopers, or two armoured fighting vehicles (often tanks). Law enforcement In non ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karlskrona
Karlskrona (, , ) is a locality and the seat of Karlskrona Municipality, Blekinge County, Sweden with a population of 66,675 in 2018. It is also the capital of Blekinge County. Karlskrona is known as Sweden's only baroque city and is host to Sweden's largest naval base and the headquarters of the Swedish Coast Guard. Historically, the city has been home to a German minority, thus enabling the formation of a German Congregational church. It also counted Jewish people in its population. In 1998, parts of the city, including the Karlskrona naval base, was declared a UNESCO World Heritage Site. History The island on which Karlskrona was built, Trossö, was owned during the 17th century by the farmer Vittus Andersson. Under Danish rule, there was another, older town called Lyckå on the mainland a couple of kilometers away. A little further away, the Danes had started to build Kristianopel before Blekinge fell under Swedish rule in 1658. Until 1679, the island and the ne ...

Kockums
Saab Kockums AB is a shipyard headquartered in Malmö, Sweden, owned by the Swedish defence company Saab Group. Saab Kockums AB is further operational in Muskö, Docksta, and Karlskrona. While having a history of civil vessel construction, Kockums' most renowned activity is the fabrication of military corvettes and submarines. Kockums worked with Northrop Grumman and Howaldtswerke-Deutsche Werft (HDW) to offer a ''Visby''-class corvette derivative in the American Focused Mission Vessel Study, a precursor to the Littoral Combat Ship program. It competed with several other concepts, including Norway's Skjold class (part of a Raytheon led group). History Kockums during the 19th century During the 1820:s the Kockums family established themselves as businesspeople in Malmö. Frans Henrik Kockum built a large fortune through an investment in tobacco production. Thanks to this he was able to purchase a large part of land 1838 south of Malmö, and between 1840 and 1841 he erec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

StanFlex
StanFlex (also known as STANFLEX or Standard Flex) is a modular mission payload system used by the Royal Danish Navy. Originally conceived during the 1980s as a way of replacing several classes of minor war vessel with a single class of multi-role ships (the ), the StanFlex system consists of weapons and equipment mounted in standardised containers, which can be loaded into slots on the ships. These containers can be swapped out in a short period of time, allowing the ship to switch between roles when needed. The success of the modular payload system led the Royal Danish Navy to design all new warships with StanFlex slots, and to install slots on older vessels during major refits. By 2012, nine ship classes capable of carrying StanFlex payloads were in service. Development During the early 1980s, the Royal Danish Navy (RDN) required replacements for three classes of minor war vessel, but could not afford to replace all 22 ships on a one-for-one basis.Scott, ''Versatility the key ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull ( keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...

Patrol Vessel
A patrol boat (also referred to as a patrol craft, patrol ship, or patrol vessel) is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine (" blue water"), estuarine (" green water"), or river (" brown water") environments. Per their name, patrol boats are primarily used to patrol a country's exclusive economic zone (EEZ), but they may also be used in other roles, such as anti- smuggling, anti-piracy, fishery patrols, immigration law enforcement, or search and rescue. Depending on the size, organization, and capabilities of a nation's armed forces, the importance of patrol boats may range from minor support vessels that are part of a coast guard, to flagships that make up a majority of a navy's fleet. Their small size and relatively low cost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
