HMS L12
HMS ''L12'' was a L-class submarine built for the Royal Navy during World War I. She was one of five boats in the class to be fitted as a minelayer. The boat survived the war and was sold for scrap in 1932. Design and description ''L9'' and its successors were enlarged to accommodate 21-inch (53.3 cm) torpedoes and more fuel. The submarine had a length of overall, a beam of and a mean draft of .Gardiner & Gray, p. 93 They displaced on the surface and submerged. The L-class submarines had a crew of 38 officers and ratings.Akermann, p. 165 For surface running, the boats were powered by two 12-cylinder Vickers diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a electric motor. They could reach on the surface and underwater. On the surface, the L class had a range of at . The boats were armed with four 21-inch torpedo tubes in the bow and two 18-inch (45 cm) in broadside mounts. They carried four reload torpedoes fo ...

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 sides 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 designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Ships Built In Barrow-in-Furness
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%).

John Cashmore Ltd
John Cashmore Ltd (also known as J Cashmore, or simply as Cashmore's or other derivations) was a company operating largely in Newport, Monmouthshire, Wales. It became best known for ship breaking and scrapping redundant British railway locomotives. History The company was founded in 1872 by a member of the Cashmore family in Horseley Heath, Staffordshire. While eventually the large part of the business was in Newport, with a business address at the Old Town Dock, the headquarters was in Great Bridge, Tipton. Scrapping of steam locomotives from the LMR, ER and WR, also took place at Gold's Hill, Great Bridge. The shipbreaking business was closed in October 1976, and the remaining business was incorporated into the Gynwed Group. Ship breaking It ran a ship breaking business on the banks of the River Usk, which had a very high tide enabling large vessels to be moved upstream. It scrapped many ex-Royal Navy ships including the following: * (Destroyer - 1914) * (Destroyer - 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Milford Haven
Milford Haven ( ) is a town and community (Wales), community in Pembrokeshire, Wales. It is on the north side of the Milford Haven Waterway, an estuary forming a natural harbour that has been used as a port since the Middle Ages. The town was founded in 1790 by William Hamilton (diplomat), Sir William Hamilton, who designed a grid street pattern. He intended it to be a whaling centre, but by 1800 it was developing as a Royal Navy dockyard which it remained until the dockyard was transferred to Pembroke, Pembrokeshire, Pembroke in 1814. It then became a commercial dock, with the focus moving in the 1960s, after the construction of an oil refinery built by Esso, to logistics for fuel oil and liquid gas. By 2010, the town's port had become the fourth largest in the United Kingdom in terms of tonnage, and continues its important role in the United Kingdom's energy sector with several oil refineries and one of the biggest Liquefied natural gas, LNG terminals in the world.

Saddle Tank (submarine)
Saddle tanks are a type of ballast tank configuration fitted to submarines. Saddle tanks are fitted in pairs external to the Submarine hull, pressure hull, one on each side, in a similar manner to that of a horse's saddle-bags, the positioning of which they resemble in appearance. Development The first effective submarines, those of World War I, had hulls that were broadly circular in cross-section, with a deck plate mounted midway. Their heavy battery tanks were mounted beneath this deck, for stability. The ballast tanks were mounted ''inside'' the pressure hull. For compactness the ballast tanks were wrapped around the batteries, low down and sharing the flat surfaces of the battery tank. The Kingston valves linking the ballast tanks to the sea could be left open, a practice known as "riding the valves", and the water level in the tanks controlled solely by the vent and blowing air valves. The drawback was that the ballast tanks, open to sea pressure, had a flat surface to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacturer, aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce Holdings, Rolls-Royce plc, which sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Platforms & Services, BAE Systems Land Systems.
