Understanding Modern Ship Navigation and Its Importance
Nowadays, sailors are well-trained to handle all modern navigation equipment to make sailing smoother and safer at sea. The vessel today is equipped with various advanced navigation systems that provide accurate voyage data. Thanks to modern facilities and automation. This is an article which covers both old and new navigation equipment used by merchant ships.
Direction & Heading Instruments
Gyro Compass
It uses a gyrocompass to determine its direction. Unlike a magnetic compass, it is not affected by an outside magnetic field. Additionally, it supplies the accurate axis of rotation for the Earth, resulting in a reliable directional source. Typically, it is fixed to the steering platform.
Magnetic Compass
To determine the planned route of a voyage, a magnetic compass is used. Along with Earth's magnetic field, it operates simultaneously. Navigators use it as their primary direction indicator. On the bridge panel, the output signal can be displayed because the magnetic transmitting compass is fixed.
Rudder Angle Indicator
It displays a ship's steering angle. The ship's navigator can adjust the steering speed and rudder angle thanks to the display's location on the equipment console on the bridge. Both the engine control room and the bridge wings have indicators for them. The signal is also available in the engine control room and the bridge wings.
Rate of Turn Indicator
This navigation tool displays the degrees of turn, i.e, how fast the vessel is turning at a constant speed. The turn rate of a ship is calculated in degrees per minute. Also, it helps the navigator to steer the course safely.
Collision Avoidance & Tracking Systems
Radar
To avoid collisions, marine vessels rely on S-band and X-band radar in Dubai to detect targets and display information on the screen such as distances from the ground or any floating objects (islands, icebergs, rocks, etc). With its rotating antenna, it detects the surroundings of a ship.
ARPA
It is a feature on the radar that constantly monitors the condition of the ship. It automatically determines the number of targets for you, such as ships, boats, stationary or floating objects etc. and denotes their speed and course accordingly.
Automatic Tracking Aid
As with ARPA, the automatic tracking system displays information about the targets tracked, both in graphical and numerical systems. This enables the vessel to travel avoiding the risk of collision.
Automatic Identification System (AIS)
AIS helps to accurately identify the position and other navigation statistics of ships. AIS sends and receives messages between ships using VHF radio channels.
Long-Range Tracking and Identification (LRIT)
LRIT is an international tracking and identification system incorporated by IMO in accordance with its SOLAS convention to provide a thorough tracking system for ships that make international voyages around the world.
Positioning & Route Management
GPS Receiver
GPS receiver is a global positioning system (GPS) receiver is a display system used to display the location of a ship using a global positioning satellite in earth orbit. You can calculate the speed, the course it is taking, and the time required to cover the distance within two points.
Electronic Chart Display Information System (ECDIS)
The Electronic Chart Display Information System (ECDIS) is a navigation chart system used on ships. A ship's location can easily be determined using this method.
Autopilot
An autopilot assists the operator in steering by holding the wheel in autopilot mode. As a result, they can concentrate on the broad aspects of the operation. Thus, it is considered one of the most effective bridge navigation aids in our marine equipment suppliers in UAE.
Depth, Speed, and Distance Measurement
Echo Sounder
There are many modern shipborne navigation instruments onboard and the echo sounder is one instrument that has been in use for nearly 100 years. With the principle of sound wave transmission, it measures the depth of water below the bottom of a ship.
Speed & Distance Measuring Equipment
This bridge equipment on a ship is used to measure the speed and distance the ship has travelled from a given point.
Sound Reception System
This speaker system becomes vital for a fully enclosed bridge. The navigator will be able to hear audible signals (for instance, the horn of another ship). Also, it helps the navigator perform a watch for evading collisions at sea. Usually, it is installed in the ship's equipment on the bridge.
Navigation Lights
According to the appropriate guidelines for the prevention of maritime accidents. All large/ small boats should have nightlights as part of their navigation systems.
Daylight Signaling Lamp
Daylight signaling lamps are used for conveying information between ships, or between ship and shore, by means of light signals, both by day and by night.
Voyage/Route Planner
Marine Digital route planner is used in ships to evade tough weather conditions and other hurdles. It helps you calculate the safest and most economical route to the port of destination.
Nautical Flags
Various types of flags with different colors and marks are used to indicate the position of a navigational vessel. Nautical flags are an International Code of Signals whose main purpose is to provide different ways of communication in different nautical situations. They can be used for communication between two ships or between the ship and the shore.
Data Recording & Monitoring Systems
Voyage Data Recorder (VDR)
There is a voice recording system in the VDR that keeps a record of the last 12 hours of conversations. Any future investigation will be based on this information. VDRs are similar to black boxes mounted on aircraft in terms of their importance.
