Founded in 1989 as Kværner Båtservice, later Kværner Mandal, and known as Umoe Mandal since 2000, the company specialises in high-speed naval vessels, mine countermeasure vessels (MCMVs) and fast patrol boats (FPBs). They supply the Royal Norwegian Navy, for whom they are currently in production with the Fast Attack Craft series Skjold.
The company is especially known for its expertise in the use of fibre reinforced plastic (FRP) technology in naval applications. It undertakes the design of naval and commercial vessels in FRP and other advanced composites structures for military applications, as well as shock design, stealth design, and EMI/EMC measures and weight/strength optimisation.
The company also produces a range of special products in its market area, such radar stealth air intakes, carbon fibre composite centrifugal fans and, through its subsidiary Umoe Ryving (established 2003), the design and production of FRP composite blades for the wind turbine industry.
Fiberglass or fibreglass 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.
A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
Aker Solutions ASA is a Norwegian engineering firm headquartered in Oslo. The firm's production is focused on energy infrastructure, including systems and services required to de-carbonize oil and gas production, build wind-to-grid infrastructure and engineer CO2 capture and sequestration.
Fibre-reinforced plastic is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.
Skjold-class corvettes are a class of six light, superfast, stealth missile corvettes in service with the Royal Norwegian Navy. The boats were formerly classed as MTBs but, from 2009, the Royal Norwegian Navy has described them as corvettes (korvett) because their seaworthiness is seen as comparable to corvettes, and because they do not carry torpedoes. They were built at the Umoe Mandal yard. With a maximum speed of 60 knots (110 km/h), the Skjold-class corvettes were the fastest combat ships afloat at the time of their introduction., as of 2023 beaten by the Abu Dhabi MAR WP-18 Interceptor.
Basalt fibers are produced from basalt rocks by melting them and converting the melt into fibers. Basalts are rocks of igneous origin. The main energy consumption for the preparation of basalt raw materials to produce of fibers is made in natural conditions. Basalt fibers are classified into 3 types: Basalt continuous fibers (BCF), used for the production of reinforcing materials and composite products, fabrics, and non-woven materials; Basalt staple fibers, for the production of thermal insulation materials; and Basalt superthin fibers (BSTF), for the production of high quality heat- and sound-insulating and fireproof materials.
The Alta class is a ship class of minesweepers operated by the Royal Norwegian Navy. An almost identical class of minehunters is known as the Oksøy class.
A stealth ship is a ship that employs stealth technology construction techniques in an effort to make it harder to detect by one or more of radar, visual, sonar, and infrared methods.
The Nasty type patrol boats were a series of fast patrol boats designed and built in Norway during the 1950s and 1960s for the Norwegian, and other, navies.
Mazagon Dock Shipbuilders Limited (MDL), formerly called Mazagon Dock Limited, is a company with shipyards situated in Mazagaon, Mumbai. It manufactures warships and submarines for the Indian Navy and offshore platforms and associated support vessels for offshore oil drilling. It also builds tankers, cargo bulk carriers, passenger ships and ferries.
A/S Westermoen Båtbyggeri og Mek Verksted was a shipyard located in Mandal, Norway. Under the leadership of Toralf Westermoen in the 1950s, the yard has produced a long range of high speed boat types, such as:
Toralf Westermoen was a pioneer for the development of high speed craft in Norway. Westermoen was involved in the companies Båtservice Verft, Westermoen Båtbyggeri og Mek. Verksted , Westermoen Hydrofoil and Westamarin , all situated in Mandal.
The Type 22 missile boat is a ship class in the Chinese People's Liberation Army Navy. The first boat was launched in April 2004 by the Hudong-Zhonghua Shipyard at Shanghai. The boats incorporate stealth features and are based on Australian-designed wave-piercing catamaran hulls that are more stable than other fast missile craft in high sea conditions. 82 of these missile boats are currently in service with three flotillas having been produced over a span of seven years, operating in squadrons of eight vessels each.
FRP is a modern composite material of construction for chemical plant, pulp and paper mill, and food and pharmaceutical equipment like tanks and vessels. Chemical equipment that range in size from less than a metre to 20 metres are fabricated using FRP as material of construction.
A continuous filament winding machine is a machine for laying filament windings continuously over a cylindrical steel band. The steel band is carried on a forward moving mandrel which is able to collapse and return to the beginning of the travel. The steel band is released after the mandrel collapses and is continuously fed back to the start of the travel where it is again wound on to the mandrel.
Intermarine is an Italian shipbuilding company, owned by the Rodriquez Cantieri Navali Group.
North Sea Boats is an international boat-building company specialized in building craft for military, law enforcement, SAR, commercial, and high-performance applications. The company has a presence in Sweden, Singapore, and Indonesia, with its headquarters located at Banyuwangi, East Java, Indonesia. North Sea Boats was founded in 2003 by John and Lizza Lundin as a trading name for PT Lundin Industry Invest.
