What is engine order telegraph?

An engine order telegraph (EOT) is a device used on ships to communicate the desired speed and direction of the engines to the engine room. It typically consists of a large dial with markings for various engine speeds and directions, which are communicated to the engine room through a series of telegraph cables.

The EOT is usually located on the ship's bridge, where the captain or officer on watch can adjust the engine settings as needed. The telegraph cables are connected to the engine controls in the engine room, allowing for quick and easy communication between the bridge and engine room without the need for verbal commands.

The EOT is an important tool for ensuring smooth and efficient operation of the ship's engines, as it allows for precise control over speed and direction changes. It is often used in conjunction with other navigation and communication systems to ensure safe and efficient navigation of the vessel.
