A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II .
Turbinia is 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 last major passenger ship built with steam turbines was Fairsky, launched in 1984. Similarly, many steam ships were re-engined to improve fuel efficiency. One high-profile example was the 1968 built Queen Elizabeth 2 which had her steam turbines replaced with a diesel-electric propulsion plant in 1986.
Steam can be used to drive a high speed turbine that is connected through some means of transmission to the driving component of the vessel. [3] These are more common on modern ships and were first used in 1897 on the steam ship Turbinia. [4] Nuclear ships almost always use a turbine to harness the energy of the steam that they produce.
While steam turbine-driven merchant ships such as the Algol-class cargo ships (1972–1973), ALP Pacesetter-class container ships (1973–1974) [37] [38] and very large crude carriers were built until the 1970s, the use of steam for marine propulsion in the commercial market has declined dramatically due to the development of more efficient ...
A steam turbine is efficient only when operating in the thousands of RPM, while the most effective propeller designs are for speeds less than 300 RPM; consequently, precise (thus expensive) reduction gears are usually required, although numerous early ships through World War I, such as Turbinia, had direct drive from the steam turbines to the ...

It specialised in building the steam turbine engines that he had invented for marine use. [1] The first vessel powered by a Parsons turbine was Turbinia , launched in 1894. [ 2 ] The successful demonstration of this vessel led to the creation of the company and the building of engines for the first two turbine-powered destroyers for the Royal ...
