23 Navigation equipment of a modern marine vessel

1. (Gyro compass)
It helps the skipper to navigate the sea and bring the ship to the desired port. The gyrocompass is superior to the magnetic compass due to the lack of additional error from magnetic fields. Each ship must have a gyrocompass course repeater at the ship’s control points.
2. Radar (Radar)
Naval vessels depend on s-Band and X-Band radars, as such radars detect any targets around the ship, which is useful in bad or foggy weather. With the help of radar, you can see the ship, land, island, yacht, navigation buoys.
3. Magnetic compass (Magnetic Compass)
The magnetic compass works by interacting with the earth’s magnetic field and its main task is to show the direction of movement of the ship, that is, the course. This navigation device is installed in the center of the direction finding deck, and its indicators are broadcast on the navigation bridge.
4. Autopilot (Autopilot)
There is a lot of navigation equipment on the bridge, but one of the most useful is the steering wheel. Its main task is to keep a given gyrocompass course, and if the gyrocompass is faulty, you can switch to a less accurate magnetic compass. With the help of the steering wheel, the bridge officer has enough time to assess the situation around the ship and react correctly in a timely manner if necessary.
5. ARPA (Automatic Radar Plotting Aid)
The main task of ARPA radar is to show where we are, and where the ships are located nearby. It also shows: course, speed, distance, time to the ship and how far our ship will diverge from others.
This navigation device automatically captures all moving objects on the radar, such as ships, yachts, buoys, etc., and shows their speed and course using a vector. If necessary, you can find out more information about the goal by clicking on the desired goal.
6. The means of automatic tracking (Automatic tracking Aid)
Just like ARPA, the auto-tracking device shows information about the tracked target in graphical and digital format. Helps the officer of the watch safely disperse from the target.
7. Lag (Speed and Distance Log Device)
This navigation device measures the speed and distance traveled by the ship from a given point. With it, you can calculate the arrival of a ship at the port, as well as transmit this information to the authorities of the port of arrival or the agent.
8. Depth sounder (Echo sounder)
There are a huge number of modern and new devices on Board the ship, but the echo sounder is one of the oldest devices, which is more than 100 years old. It is used to measure the depth under the ship, by giving a sound pulse that bounces off the bottom and returns back to the source.
9. ECDIS Electronic maps
ECDIS is an electronic navigation system that combines all paper maps of the world. It is used on all ships of the world, allowing the navigation officer to plan the route many times faster.
10. Automatic identification system (AIS)
AIS is one of the ship’s navigation devices, which helps to identify the location of the nearest ships, as well as their data, which allows the watch officer to timely, for example, find out the name of the ship with which he wants to contact by radio.
11. long-range ship identification and location control Systems (LRIT system)
LRIT is an international ship tracking and identification system. It is found on ships over 300 GRT. Improves tracking of the ship from the shore.
12. Rudder angle indicator)
As the name says, indicates the steering angle. It is located in several places on the bridge, and this is near the steering wheel, on the wings of the bridge and in the engine room.
13. Voyage data recorder (Voyage data Recorder, VDR)
It is a kind of black box for the ship. An extremely important device of the ship’s navigation equipment, which constantly records all the necessary information for future investigation of an accident on the ship. There are many types of data loggers, but they all provide data for the last 12-24 hours before the accident.
14. The speed of rotation of the vessel (Rate of turn)
This navigation equipment shows how fast the ship is turning with a fixed rudder angle. Measured in angles per minute.
15. GPS receiver (GPS/DGPS receiver)
In other words, a global positioning system. Allows you to find out the exact location of the ship. With this device, the watch assistant can find out the coordinates of the ship’s location, speed, course and time to overcome the distance between two given points.
16. The system of reception of sound (Sound reception system)
This system is necessary for ships with a fully enclosed bridge. The system allows the watch officer to hear external signals from within (such as identification beeps in fog).) from other vessels nearby. This device is built into the navigation console and helps the officer to keep watch according to the rules of the ippcc.
17. Navigation lights
All vessels, both small and large, must have identification night lights. An extremely important part of the navigation system, without which it is impossible to swim in the seas and oceans.
18. Sound the horn (Ship whistle)
Ship Typhon is most often duplicated. One is powered by air pressure and the other is powered by electricity. The ship’s sound signal must be operated in two ways: by electricity and manually. It is used in difficult navigation cases such as: bad weather, fog, poor visibility, heavy traffic of ships and so on.
In emergency situations, the horn helps to warn the crew of an emergency on Board the ship.
19. Daylight signaling lamp (daylight signaling lamp or ALDIS lamp)
In addition to sound, there are also light warning lights for emergencies, which can also be used at night. Like other emergency equipment of the ship, power for the lamp can be supplied not only through the main power grid of the ship, but also from emergency batteries.
20. GMDSS equipment (GMDSS console panel)
It is an international system that uses terrestrial and satellite technology and shipboard radio systems. The system immediately warns ground services about an emergency situation with sea vessels. It includes such marine equipment as: Inmarsat-C, VHF, MF/HF, Navtex, radiotelex, SART, EPIRB.
21. Ship flags (Flags Ship)
Many flags are stored on the bridge. There are flags of countries that the ship must hang when crossing the territorial waters of the country, as well as signal flags are stored on the bridge. Signal flags have been used since ancient times, there are a huge number of them, and they have a huge number of meanings. The most commonly used flags are Hotel, Quebec, and Bravo, which individually indicate that a pilot is on Board, a quarantined ship, and a dangerous cargo or dangerous operations are on Board.
22. Facsimile (Facsimile)
In other words, it is a Fax machine that provides weather data for the ship. Data is provided in the form of a world map. It shows cyclones and anticyclones, as well as wind speed and direction.
23. the system For Monitoring the capacity of the Watch Mate (BNWAS)
And in Russian it sounds like a system for Monitoring the Capacity of the Watch Mate . The essence of this device is not to let the officer of the watch fall asleep. It works by the method of an alarm clock and can make a nasty sound every 3, 9 and 12 minutes, if you do not press the right button in time.
Without modern navigation equipment, it would not be as safe to move around in sea waters as it is now. If you have encountered any new equipment on the bridge, please share it in the comments, and I will definitely add it to the article.
