A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century.
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 19th century; 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 incorrectly 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.
Turbinia was the first steam turbine-powered steamship. Built as an experimental vessel in 1894, and easily the fastest ship in the world at that time, Turbinia was demonstrated dramatically at the Spithead Navy Review in 1897 and set the standard for the next generation of steamships, the majority of which would be turbine powered. The vessel is currently located at the Discovery Museum in Newcastle upon Tyne, North East England, while her original powerplant is located at the Science Museum in London.
RMS Arlanza was a 14,622 GRT ocean liner of the Royal Mail Steam Packet Company. She was built in Belfast in 1912 for RMSP's scheduled route between England and South America. She was a Royal Navy armed merchant cruiser from 1915 until 1920. She returned to civilian liner service in 1920 and was scrapped in 1938.
White's Marine Engineering Company was a British marine engineering company in Hebburn on Tyneside, that made marine steam engines in the 1930s.
Parsons Marine Steam Turbine Company was a British engineering company based on the River Tyne at Wallsend, North East England.
RMS Carmania was a Cunard Line transatlantic steam turbine ocean liner. She was launched in 1905 and scrapped in 1932. In World War I she was first an armed merchant cruiser (AMC) and then a troop ship.
The three Chester-class cruisers were the first United States Navy vessels to be designed and designated as fast "scout cruisers" for fleet reconnaissance. They had high speed but little armor or armament. They were authorized in January 1904, ordered in fiscal year 1905, and completed in 1908. In 1920 all scout cruisers were redesignated as "light cruisers" (CL).
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through 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 internal combustion engine driving 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 Megantic was a British transatlantic ocean liner that was built in Ireland and launched in 1908. She was one of a pair of sister ships that were ordered in 1907 by Dominion Line but completed for White Star Line.
TSS Manxman was a passenger ferry launched from the Cammell Laird shipyard, Birkenhead, on 8 February 1955. She was the final vessel in a class of six similar ships, the Six Sisters, ordered by the Isle of Man Steam Packet Company, and was the second of the Company's ships to carry this name. She was withdrawn from service in 1982. Following a failed preservation attempt, and featuring in a music video in the process, the ship was broken up at Sunderland in 2012.
TS King Edward was an excursion steamer built at Dumbarton for service down the River Clyde to the Firth of Clyde and associated sea lochs on the west coast of Scotland, as far as Campbeltown. The first commercial vessel to be driven by steam turbines, King Edward operated as a Clyde steamer for half a century from 1901 until 1951, interrupted only by service in the two world wars. The success of the vessel quickly led to the adoption of turbine propulsion for all manner of merchant vessels, from channel ferries and coastal steamers to transatlantic liners.
SS Glentworth was a shelter deck cargo steamship built in 1920 by Hawthorn Leslie & Co. in Newcastle-upon-Tyne, England for R.S. Dalgliesh and Dalgliesh Steam Shipping Co. Ltd., also of Newcastle-upon-Tyne. After the Great Depression affected UK merchant shipping in the first years of the 1930s, Dalgliesh sold Glentworth to a company controlled by Counties Ship Management who renamed her SS Box Hill.
SS Rochambeau was a French transatlantic ocean liner of the Compagnie Générale Transatlantique (CGT). She was launched in 1911 and was the first French ship to be powered by a combination of reciprocating steam engines and steam turbines.
SS Nailsea Meadow was a UK cargo steamship. She was launched in 1936 in Sunderland, England, and sunk by a U-boat in the Indian Ocean in 1943.
SS Otaki was a New Zealand Shipping Company refrigerated cargo steamship that was built in Scotland in 1908 and sunk by a German merchant raider in 1917.
SS Boniface was a UK-built steam cargo liner that was launched in 1928 and scrapped in 1961. She spent most of her career with Booth Line. After Alfred Booth and Company sold its shipping line in 1946 the ship changed hands three times and was successively named Browning, Sannicola and Muzuho Maru.
SS Florian was an Ellerman Lines cargo steamship that was launched in 1939 and completed in 1940. A U-boat sank her with all hands in 1941 in the Battle of the Atlantic.
SS Adderstone was a cargo ship that was built in Ireland in 1920. She was launched as the turbine steamship War Bamboo, and for most of her career she was called Boswell (1920–34), Germa (1937–51), or Norway Maru (1951–1968/70). She spent only about three years as Adderstone (1934–37). However, it was as Adderstone that the ship was the test-bed for an innovative development in marine steam propulsion, which used reduction gearing not only for an exhaust steam turbine but also for a high-speed reciprocating steam engine.
SS Agios Georgios IV was a Greek-owned cargo steamship that was built in England in 1938 and sunk by a Japanese submarine in the Indian Ocean in 1942. Agios Georgios IV was one of a relatively small number of steamships that had White combination engines. This was a combination of a high-speed four-cylinder compound steam engine that drove the propeller shaft via single-reduction gearing, with an exhaust steam turbine that drove the same shaft via double-reduction gearing.
