What is engine-room telegraph?
Definition of engine-room telegraph : a signaling device for transmitting orders from an officer on the bridge of a ship to the engineer in charge relating to the direction and speed of the engine.
What is full ahead?
(idiomatic) Maximum effort without reservations or delay. We got the OK on the conversion project. It’s full speed ahead.
How did Morse code work on ships?
In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver’s speaker as beeps, which are translated back to text by an operator who knows Morse code.
Do so at a flank bell?
At the conclusion of Chief of Naval Operations Admiral Michael Gilday’s January 2019 FRAGO, he noted “Your tenacity, drive, and initiative will take us where we need to go—and do so at a flank bell.” A flank bell is the way the joint force must approach developing manned-unmanned teaming.
What is astern in ship?

What is a slow bell?
The more complex explanations indicate the “slow bell” signal is an engine order telegraph, or E.O.T., originating when the ships’ sailors were notified of the captains’ or pilots’ orders by the ringing or clanging of a bell. This was before the many communication systems they use today.
Did Titanic use Morse code?
Two young Marconi-employed operators, chief telegraphist Jack Phillips and his assistant Harold Bride, sent Morse code “Marconigrams” on behalf of Titanic’s well-heeled customers 24 hours a day during its maiden voyage in April 1912.
What does flank mean on a ship?
Flank speed is an American nautical term referring to a ship’s true maximum speed but it is not equivalent to the term full speed ahead. Usually, flank speed is reserved for situations in which a ship finds itself in imminent danger, such as coming under attack by aircraft.
Why is it called flank speed?
Named after the extreme engine order given to ship handlers to evade danger or outpace threats, Flank Speed will be an evolving information technology initiative and the epicenter of Navy unclassified systems for years to come.
What is the most famous Morse code?
What hath God wrought.
In 1884, during a demonstration to the US Congress, four words were sent on a telegraph line from Washington, DC, to Baltimore, Maryland. The message? “What hath God wrought.”
What is Morris code?
The term Morse Code refers to either of two systems for representing letters of the alphabet, numerals, and punctuation marks by an arrangement of dots, dashes, and spaces. The codes are transmitted as electrical pulses of varied lengths or analogous mechanical or visual signals, such as flashing lights.
What does Dead slow ahead mean?
“Dead slow ahead” means “travel forwards as slowly as possible without actually stopping”.
Why did Titanic go full astern?
By the laws of hydrodynamics, when the Titanic’s propellers were stopped from turning ahead, the rudder effect decreased; the port turn continued, but the rate of turn decreased. When the propellers were turned astern, all rudder effect was negated due to the cavitation.
What does abeam mean?
Definition of abeam : off to the side of a ship or plane especially at a right angle to the middle of the ship or plane’s length.
What is the device that is used to move the ship forward and astern?
Propeller, Types of Propellers and Construction of Propellers. A propeller is a rotating fan-like structure that is used to propel the ship by using the power generated and transmitted by the main engine of the ship.
What is Bell book in ship?
Definition of bell book : a book in which a ship’s engineer records speeds, directions, and engine data.
How to control the speed of a ship?
Speed must be brought firmly under control at greater distances from the berth. It is usually obvious when the speed of a ship is too slow and can be easily overcome with a small increase in revolution; it is not always obvious when the speed is too high.
What happens to the speed as the ship approaches the mile mark?
As the ship approaches the mile mark, speed is still over 3 knots, despite a rapid reduction in rpm. It is now necessary to stop the engine and thence sustain a prolonged period of increasing stern power in order to. stop the ship in time.
Why is the noise of the engine on a merchant ship undesirable?
Such noise is undesirable during conflicts because it can give away a vessel’s position. Modern engine room telegraph/remote control handle in Engine Control Room (ECR) on board a merchant ship.
What are the effects of excessive speed on a ship?
Many casualties are proven to occur as a direct result of excessive speed. Its effect can be insidious and a Master may find that he cannot keep up with events, which are happening too quickly. Effective control of the ship is slowly but inexorably lost.
