A ship's horn is known as a whistle and it is generally provided in duplicate. One is driven by air and the other is electrically operated. The whistle should be both manually and electrically operational from the bridge.

Ship Whistle

is also among the types of a navigation system which helps to pinpoint the location and other navigational statistics of ships.

AIS

a development in the navigational chart system used in naval vessels and ships. With the use of the electronic navigation equipment, it has become easier for a ship's navigating crew to pinpoint locations, and attaining directions are easier than before.

Ecdis

is one of the instruments which has been in the play from almost 100 years now. It is used to measure the depth of the water below the ship's bottom using sound waves which work on the principle of transmission of sound waves and an audio pulse which will bounce off a reflecting layer, returning as an echo to the source.

Echo Sounder

is a monitoring and Alarm system which notifies other navigational officers or master of the ship if the officer on watch (OOW) does not respond or he/she is incapable of performing the watch duties efficiently, which can lead to maritime accidents.

Bnwas

The seagoing vessels depend on S-band(10cm) and X- band(3cm) frequency radar system for navigation as it can detect targets and display the information on the screen such as the distance of the ship from land, any floating objects (an island, rocks, iceberg etc.), other vessels, and obstacles to avoid a collision. It is a rotating antenna which discovers the surrounding area of the

Radar

All boats - whether big or small are required to have night lights as a part of the navigation systems. This system was introduced in the year 1838 by the United States and then was followed by the United Kingdom in 1849.

Navigational Lights

It is used for finding the right direction. Unlike magnetic compass, gyro compass is not hampered by an external magnetic field. It is used to find the correct North Position

Gyro compas

as the name indicates, provides the angle of the rudder. The display is provided on the navigation bridge equipment console so that the ship navigation officer can control the rate of turn and rudder angle of the ship.

Rudder angle Indicator

is considered to be one of the most effective bridge navigational equipment as it assists the human operator in controlling the ship by keeping the steering in autopilot, which allows them to concentrate on broad aspects of the operation

Auto Pilot

Speed & Distance Log Device - This bridge equipment on a ship is used to measure the speed and the distance travelled by a ship from a set point. By calculating the same, ETA of the ship is adjusted or given to the port authority and agent.

Speed and distance Log device

receiver is a display system used to show the ship's location with the help of Global positioning satellite in the earth's orbit.

Gps

This bridge navigational equipment constantly monitors the ship's surrounding and automatically acquires the number of targets, in this case; ships, boats, stationary or floating objects etc., and plot their speeds and courses respectively.

ARPA

is an international tracking and identification system incorporated by the IMO under its SOLAS convention to ensure a thorough tracking system for ships of 300 gross tons and above which are on international voyages across the world. This maritime equipment is fitted to improve the maritime domain awareness.

Lrit

is a crucial instrument among the ship navigation equipment list which is installed on a ship to continuously record vital information related to the operation of a vessel. It contains a voice recording system for a period of at least the last 12 hours. This recording is recovered and made use of for investigation in events of accidents..

Vdr

This navigational tool indicates how fast the ship is turning at a steady rate (useful during pilotage and manoeuvring), normally shown as a number of degrees turned.

Rate of turn Indicator

This acoustic system is required for a ship with a fully enclosed type bridge. It enables the navigating officer inside the cabin to listen to the sound signals (such as fog or ship's horn) from other ships in the vicinity.

Sound reception system
