Steam turbines were fueled by coal or, later, fuel oil or nuclear power. The marine steam turbine developed by Sir Charles Algernon Parsons [3] raised the power-to-weight ratio. He achieved publicity by demonstrating it unofficially in the 100-foot (30 m) Turbinia at the Spithead Naval Review in 1897. This facilitated a generation of high-speed ...
The production of steam by nuclear marine propulsion units is almost exclusively done in aircraft carriers and submarines, due to the regulations limiting distribution and ownership of the radioactive fuels used to power the plants. Nuclear systems present an additional danger due to the radioactivity of the fuel source and risk of reactor breach.
The development of steam turbine marine propulsion from 1894 to 1935 was dominated by the need to reconcile the high efficient speed of the turbine with the low efficient speed (less than 300 rpm) of the ship's propeller at an overall cost competitive with reciprocating engines.
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 .
The Invincible-class battlecruisers all used Parsons propulsion systems. In 1944, Parsons was one of 19 companies which formed the 'Parsons and Marine Engineering Turbine Research and Development Association', usually known as Pametrada. The destroyer HMS Glamorgan, launched in 1964, [2] had a Parsons propulsion system.
If the turbines do not drive a propeller shaft directly and instead a turbo-electric transmission is used, the system is known as COGES (combined gas turbine-electric and steam). COGAS differs from many other combined marine propulsion systems in that it is not intended to operate on one system alone.
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 ...
The most efficient steam engine used for marine propulsion is the steam turbine. It was developed near the end of the 19th century and was used throughout the 20th century. It was developed near the end of the 19th century and was used throughout the 20th century.
