Steam-powered vessel

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.Also known as a propeller, a screw is a device that uses sloped surfaces to transition rotational motion created by the steam engine into an axial force that moves the vessel forward.Systems that use propellers are regarded as more efficient than comparative paddle-wheels due to the reduced weight of rotating components and smaller equipment footprint.Steam powered tugboats were created for the purpose of manipulating larger vessels at within ports or areas with limited maneuverability.If over pressurization occurs and safety relief systems malfunction it is possible for a boiler to explode and cause damage to people and equipment surrounding it.The ship sank only days into its maiden voyage from Southampton to New York after it struck an iceberg and took on water, killing over 1,500 people.[10] The RMS Lusitania was a steam-propelled passenger vessel sunk off the Old Head of Kinsale, Ireland by a German U-boat in 1915.
