An engine order telegraph or E.O.T., also referred to as a Chadburn, [1] is a communications device used on a ship (or submarine) for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed.
A telegraph message sent by an electrical telegraph operator or telegrapher using Morse code (or a printing telegraph operator using plain text) was known as a telegram. A cablegram was a message sent by a submarine telegraph cable, [ 4 ] often shortened to "cable" or "wire".
An engine order telegraph dial located in the engine compartment of U-505. "MT" is Maschinen Telegraf, (Telegraph Machine), and "Bb", indicating Backbord, (Port). The Type IXC was a further refinement of the class with storage for an additional 43 tonnes of fuel, increasing the boat's range.
Sailors stand lee helm and helmsman watch. Traditionally, two stations are on the bridge of a ship for controlling the vessel's maneuvers: the helm, which uses a wheel (or touchscreen equivalent) to send signals to control the position of the rudder or rudders, and the lee helm, which traditionally inputs speed commands by operating an engine order telegraph to send engine commands to the ...
The Commonwealth navies use the following telegraph commands: Slow ahead/astern, the number of revolutions is standardized for the individual ship and is unstated; Half ahead/astern, accompanied by an order for a power setting (e.g., "half ahead both engines, revolutions 1,500") Full speed ahead/astern. This is reserved for emergencies and as ...
The first steering engine with feedback was installed on Isambard Kingdom Brunel's Great Eastern in 1866. [2] Designed by Scottish engineer John McFarlane Gray and built by George Forrester and Company , this was a steam-powered mechanical amplifier used to drive the rudder position to match the wheel position.

A sample UML class and sequence diagram for the Command design pattern. [3]In the above UML class diagram, the Invoker class doesn't implement a request directly. Instead, Invoker refers to the Command interface to perform a request (command.execute()), which makes the Invoker independent of how the request is performed.
