SS Primrose Hill
SS ''Primrose Hill'' was a British CAM ship that saw action in World War II, armed with a catapult on her bow to launch a Hawker Sea Hurricane. She was completed by William Hamilton & Co in Port Glasgow on the Firth of Clyde in September 1941. ''Primrose Hill'' was managed by Counties Ship Management Ltd of London (CSM), an offshoot of the Rethymnis & Kulukundis shipbroking company. ''Primrose Hill'' was CSM's second CAM ship, in effect replacing ''Michael E'' that had been torpedoed and sunk three months previously on her maiden voyage. ''Primrose Hill''s navigation equipment included an echo sounding device and a gyrocompass. Primrose Hill SS was a British Cargo Steamer of 7,628 tons built in 1941 by William Hamilton's & Co, Port Glasgow, Yard no 448 for Ruthi, Kuluku. Propulsion ''Primrose Hill'' had six corrugated furnaces that heated two 225 lbf/in2 single-ended boilers with a combined heating surface of . The boilers raised steam for a 443 NHP triple-expansion engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sister Ship
A sister ship is a ship of the same Ship class, class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s trio, consisting of , and . As with some other liners, the sisters worked as running mates. Of the three sister ships, ''Titanic'' and ''Britannic'' would both sink within a year of being launched, while RMS ''O ...

Gold Coast (British Colony)
The Gold Coast was a British Empire, British Crown colony on the Gulf of Guinea in West Africa from 1821 until its independence in 1957 as Ghana. The term Gold Coast is also often used to describe all of the four separate jurisdictions that were under the administration of the Governor of the Gold Coast. These were the Gold Coast itself, Ashanti (Crown Colony), Ashanti, the Northern Territories of the Gold Coast, Northern Territories protectorate and the British Togoland, British Togoland trust territory. The first European explorers to arrive at the coast were the Portuguese in 1471. They encountered a variety of African kingdoms, some of which controlled substantial deposits of gold in the soil. In 1483, the Portuguese came to the continent for increased trade. They built the Castle of Elmina, the first European settlement on the Gold Coast. From here they acquired slavery, slaves and gold in trade for European goods, such as metal knives, beads, mirrors, rum, and guns. News ...

ON Convoys
The ON and later ONS convoys were a series of North Atlantic trade convoys running Outbound from the British Isles to North America during the Atlantic campaign of the Second World War. The ON convoys replaced the earlier OA/OB series of outbound convoys in July 1941 and ran until the end of the campaign in May 1945. They were organized as alternating fast and slow convoys until March 1943, when the ONS series was begun to take over the slow trans-Atlantic traffic, after which all in the ON series were fast. ON convoys From 7 September 1939, shortly after the outbreak of the Second World War, all traffic outbound from Britain was organized into the OA and OB series, sailing from London via the English Channel (OA) and from Liverpool via St Georges Channel (OB) into the South-Western Approaches. These would be escorted until beyond the range of U-boat patrols before the ships dispersed to reach their destinations. After the fall of France in June 1940 these were successively reor ...

Pounds Per Square Inch
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), is a unit of measurement of pressure or of stress based on avoirdupois units and used primarily in the United States. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately . The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyrocompass
A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth (or another planetary body if used elsewhere in the universe) to find geographical Direction (geometry), direction automatically. A gyrocompass makes use of one of the seven fundamental ways to determine the heading of a vehicle. A gyroscope is an essential component of a gyrocompass, but they are different devices; a gyrocompass is built to use the effect of gyroscopic precession, which is a distinctive aspect of the general gyroscopic effect. Gyrocompasses, such as the fibre optic gyrocompass are widely used to provide a heading for navigation on ships. This is because they have two significant advantages over magnetic compasses: * they find true north as determined by the axis of the Earth's rotation, which is different from, and navigationally more useful than, Magnetic North Pole#Magnetic north and magnetic declination, ''magnetic'' north, and * they have a ...

Echo Sounding
Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth (coordinate), depth of water (bathymetry). It involves transmitting acoustic waves into water and recording the time interval between emission and return of a pulse; the resulting time of flight, along with knowledge of the speed of sound in water, allows determining the distance between sonar and target. This information is then typically used for navigation purposes or in order to obtain depths for Nautical chart, charting purposes. Echo sounding can also be used for ranging to other targets, such as fish schools. Hydroacoustic assessments have traditionally employed mobile surveys from boats to evaluate fish biomass and spatial distributions. Conversely, fixed-location techniques use stationary transducers to monitor passing fish. The word ''Depth sounding, sounding'' is used for all types of depth measurements, including those that don't use sound, and is unrelated in origin to ...

She had a depth of and a draught of . She was measured at and . She had six corrugated furnaces feeding two single-ended boilers with a combined heating surface of . The boilers fed a 443 nominal horsepower triple-expansion steam engine that had cylinders of , and diameter by stroke. The engine was built by D ...

Shipbroking
Shipbroking is a financial service, which forms part of the global shipping industry. Shipbrokers are specialist intermediaries/negotiators (i.e. brokers) between shipowners and charterers who use ships to transport cargo, or between buyers and sellers of vessels. History In the 19th century, it was the work of ship-brokers to procure goods on freight or a charter for ships outward bound. They also went through the formalities of entering and clearing vessels at the customs-house. They collected the freight on vessels brought into port and took an active hand in the management of all business matters between ship-owners and merchants, whether shippers or consignees, for which they were paid a fee. In major British ports, ship-brokers were also usually insurance-brokers. Modern shipbroking Some brokerage firms have developed into large companies, incorporating departments specialising in shipping's various sectors, ''e.g.'' Dry Cargo Chartering, Tanker Chartering, Container Ch ...
