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.
Marine steam engines were the first mechanical engines used in marine propulsion, however they have mostly been replaced by two-stroke or four-stroke diesel engines, outboard motors, and gas turbine engines on faster ships. Nuclear reactors producing steam are used to propel warships and icebreakers. Nuclear reactors to power commercial vessels has not been adopted by the marine industry. Electric motors using electric battery storage have been used for propulsion on submarines and electric boats and have been proposed for energy-efficient propulsion. Development in liquefied natural gas (LNG) fueled engines are gaining recognition for their low emissions and cost advantages. Stirling engines, which are more efficient, quieter, smoother running producing less harmful emissions than diesel engines, propel a number of small submarines. The Stirling engine has yet to be upscaled for larger surface ships.

Shipping counts the costs of green regulation. In the aftermath of the recent SMM Exhibition in Hamburg, Paul Fanning, editor of Marine Propulsion, reflects on the effect environmental regulation is having on the industry.
Test running following major restoration. Engine was stripped down to the last nut and bolt, everything was checked, measured, remachined or replaced to bring it back to a better than new condition. This engine is now available to purchase and will be fitted with a new PRM500 hydraulic gearbox and alternator before despatch.

Among other critical activities,gas turbines play an extensive role in electric power generation, and marine propulsion for naval vessels and cargo ships. In the most exhaustive volume to date, this text examines the foundation of aircraft propulsion: aerodynamics interwoven with thermodynamics, heat transfer, and mechanical design. With a finely focused approach, the author devotes each chapter to a particular engine type, such as ramje...
A project developed by MAN Diesel & Turbo and Odfjell, results verified by Norwegian Marine Technology Research Institute and Rightship In today’s tough market situation staying ahead of your competitors is vital in order to run a prosperous and attractive business. The Norwegian company Odfjell is one of the world’s leading chemical tanker operators and intends to stay in that position. Therefore, Odfjell is in close cooperation with MAN Diesel & Turbo to upgrade the propulsion system on 19 of the vessels in their fleet. The propulsion system is upgraded with a combination of the highly efficient MAN Alpha Kappel propeller concept and the MAN Alpha rudder bulb & fairing cone concept. Engine power limitation (EPL) and a change of the gear ratio of the power take out (PTO) for the shaft g...

Nuclear marine propulsion is propulsion of a ship with power provided by a nuclear reactor. Naval nuclear propulsion is propulsion that specifically refers to naval warships Very few experimental civil nuclear ships have been built.
Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear power plant. The power plant heats water, to produce steam and it is this steam that powers the steam turbines and turbo generators. The power is then transferred to a gearbox that reduces the ratio by around 50 to 1 and this powers the propulsor. Naval nuclear propulsion is propulsion that specifically refers to naval warships. Very few experimental civil nuclear ships have been built. This video is targeted to blind users. Attribution: Article text available under CC-BY-SA Creative Commons image source in video
