Complete Growth Overview on Marine Propulsion System Industry

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 powered by mechanical systems consisting of an electric motor or motor that turns a propeller, or less often in pump jets, an impeller. Marine engineering is the discipline that deals with the design process of marine propulsion systems.

Labor in the form of paddling and sailing were the first forms of ship propulsion. A number of rowing galleys, some of which were equipped with sails, also played an important early role. The first advanced mechanical means of propelling a ship was the ship steam engine introduced in the early 19th century. During the 20th century, it was replaced by two-stroke or four-stroke diesel engines, outboard engines, and gas turbine engines on faster ships. Marine nuclear reactors, which appeared in the 1950s, produce steam to power warships and icebreakers. The commercial application that was attempted at the end of the decade failed to catch on.

Electric motors with electric battery storage were used to propel submarines and electric boats and were proposed for energy-efficient propulsion. The development of liquefied natural gas (LNG) engines is recognized for their low emissions and cost benefits. Stirling engines, which run quieter and quieter, power a number of small submarines to run as quietly as possible. Its design is not used for civil marine applications because of its lower overall efficiency than internal combustion engines or power turbines.
