A motor ship or motor vessel is a ship propelled by an internal combustion engine, usually a diesel engine. The names of motor ships are often prefixed with MS, M/S, MV [1] or M/V. [2]
Engines for motorships were developed during the 1890s, and by the early 20th century, motorships began to cross the waters. [3] [4]
The first diesel-powered motorships were launched in 1903: the Russian Vandal (the first equipped with diesel-electric transmission) and French Petite-Pierre. There is disagreement over which of the two was the first.
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for paddle steamer or "SS" for screw steamer. As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for motor vessel, so it is not correct to use "SS" for most modern vessels.
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S or PS ; however, these designations are most often used for steamships.
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans.
A diesel–electric transmission, or diesel–electric powertrain is a transmission system for vehicles powered by diesel engines in road, rail, and marine transport. Diesel–electric transmission is based on petrol–electric transmission, a very similar transmission system used for petrol engines.
Selandia was the name of three ships of the Danish East Asiatic Company, the best known of which, the first MS Selandia of 1912, was the most advanced ocean-going diesel motor ship in her time.
Royal Mail Ship, usually seen in its abbreviated form RMS, is the ship prefix used for seagoing vessels that carry mail under contract to the British Royal Mail. The designation dates back to 1840. Any vessel designated as "RMS" has the right both to fly the pennant of the Royal Mail when sailing and to include the Royal Mail "crown" insignia with any identifying device and/or design for the ship.
A & J Inglis, Ltd, was a shipbuilding firm founded by Anthony Inglis and his brother John, engineers and shipbuilders in Glasgow, Scotland in 1862. The firm built over 500 ships in a period of just over 100 years. Their Pointhouse Shipyard was at the confluence of the rivers Clyde and Kelvin. They constructed a wide range of ships, including Clyde steamers, paddle steamers and small ocean liners. In wartime, they built small warships, and in the period after World War II, they built a number of whalers.
Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems.
SS Clan Fraser was a British cargo steamship. She served in the Second World War and was bombed and sunk in Greece in 1941.
SS Clan Chisholm was a British cargo steamship. She was torpedoed and sunk in the Second World War while carrying cargo from India to Scotland.
Brighton was a 1,384 GRT steamship which was built in 1903 for the London, Brighton and South Coast Railway and London and South Western Railway. She passed to the Southern Railway on 1 January 1923. In 1930, she was sold to W E Guinness and converted to a private yacht, Roussalka. She was wrecked at Killary Bay on 25 August 1933.
MV Wotan was a 5,703 GRT tanker that was built in 1913 by Reiherstieg Schiffswerft & Maschinenfabrik, Hamburg, Germany. Requisitioned by the Imperial German Navy in 1914, she served until 1915 as SMS A and was then returned to her owners. Ceded to the United States in 1919, she was operated until 1920 then laid up following an engine failure.
SS Hertford was a refrigerated cargo steamship that was launched in Germany in 1917, seized by the United Kingdom in 1920 as World War I reparations, and sunk by a U-boat in 1942 with the loss of four members of her crew.
SS Mohamed Ali El-Kebir, formerly SS Teno, was one of a pair of steam turbine ocean liners built in Scotland in 1922 for the Chilean company CSAV. She and her sister ship Aconcagua ran between Valparaíso and New York via the Panama Canal until 1932, when CSAV was hit by the Great Depression and surrendered the two ships to the Scottish shipbuilder Lithgows to clear a debt.
Steam-powered vessels include steamboats and steamships. Smaller steamboats were developed first. They were replaced by larger steamships which were often ocean-going. Steamships required a change in propulsion technology from sail to paddlewheel to screw to steam turbines. The latter innovation changed the design of vessels to one that could move faster through the water. Engine propulsion changed to steam turbine in the early 20th century. In the latter part of the 20th century, these, in turn, were replaced by gas turbines.
SS Karsik was a German-built cargo steamship. Deutsche Schiff- und Maschinenbau (Deschimag) built her as Soneck for Deutsche Dampfschifffahrts-Gesellschaft "Hansa" in 1938.
Horace See was an American mechanical engineer, marine engineer, naval architect, inventor, and superintendent. He is known as principal naval architect at the William Cramp & Sons shipyard in Philadelphia, and as president of the American Society of Mechanical Engineers in the year 1888–89.
RMS Asturias was a Royal Mail Lines ocean liner that was built in Belfast in 1925. She served in the Second World War as an armed merchant cruiser until she was crippled by a torpedo in 1943. She was out of action until 1948 when she returned to civilian service as an emigrant ship. She became a troop ship in 1954 and was scrapped in 1957.
SS Bärenfels was a German steam cargo liner that was launched in 1921 for DDG Hansa. In 1940, she took part in the German invasion of Norway and was sunk by Fleet Air Arm dive bombers. Her wreck was raised, and in 1941, she was returned to service. In 1944, a Royal Navy midget submarine sank her, killing 11 of her complement. In 1947, her wreck was raised to be scrapped, but while under tow she sank a third time.
SS Algarve was a Danish cargo steamship that was built in 1921 for DFDS. After Germany invaded Denmark in April 1940 Algarve was transferred to the UK Ministry of War Transport. In 1941 an E-boat sank her with all hands in the North Sea.
