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.
An engine order telegraph, used to send instructions from the bridge of a ship to the engine room, fails to meet both criteria; it has a limited distance and very simple message set. There was only one ancient signalling system described that does meet these criteria.
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.
The last was an emergency telegraph, which also communicated with the engine room. It was only used if the other two failed. [2] The telegraphs connected to Titanic's engine room were used by the officer of the watch or the commanding officer to communicate any orders concerning forward and astern speed.
Helm orders would be passed to an enclosed wheel house, where the coxswain or helmsman operated the ship's wheel. Engine commands would be relayed to the engine officer in the engine room by an engine order telegraph that displayed the captain's orders on a dial. The engine officer would ensure that the correct combination of steam pressure and ...
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 ...
When Tufan Erginbilgic became Rolls-Royce’s CEO last January, he came in with a qualm—that the company was a "burning platform" that was underperforming “every key competitor out there ...
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.
