Service premises on a ship are premises in which the crew permanently or temporarily performs work on the operation of the ship:

Engine room;
Service and utility rooms (lantern room, painting room, skipper room, carpentry room and some others).

The service premises associated with the management of the vessel are located mainly on the navigation bridge deck.

Walking bridge. The navigation and wheelhouses are located on it - the place where the ship is controlled and the navigation staff keeps watch. Modern ships usually have a closed bridge. Its open areas on each side are called wings.

Rice. 1 Navigation bridge: a - semi-closed; b - closed

An upper bridge is installed on the roof of the navigation bridge. This high-mounted and completely open bridge provides good visibility over the entire horizon and is used when maneuvering in narrow spaces, in ice, and for conducting navigational and astronomical observations.

The wheelhouse is a small enclosed space with a glazed forward bulkhead.

The wheelhouse is equipped with:

Helm stand;
Travel magnetic compass;
Gyrocompass repeaters;
Machine telegraph and other necessary equipment.

Next to the helm is the chart room, equipped with a large table for storing and laying out charts, as well as several cabinets and shelves for storing navigational instruments and manuals. On ships with a large enclosed bridge, the charthouse and wheelhouse are often located in the same room, separated by a curtain.

It is quite common now for the wheelhouse to have a glazed and aft bulkhead to provide visibility to the stern.

A type of ship bridge is a transition bridge located above the upper deck for communication between superstructures or for transition from one side to another. Such bridges are installed on tankers due to the increased floodability of the deck and on fishing vessels, whose upper deck is occupied by a large number of deck and fishing mechanisms.

The radio room, if possible, is located on the navigation bridge deck, which ensures fast and reliable transmission of all received correspondence to the officer of the watch.

Service and utility premises. They are most often located in tank superstructures, which allows them to be isolated from other rooms.

Ship's equipment (cables, hooks, staples, blocks, etc.) is stored in the skipper's storeroom. In cases where the skipper's room is small, the upper part of the forepeak, separated from the ballast tank by a waterproof platform, is used for storing equipment.

The lantern and paint rooms are designed to store lanterns and paints, as well as painting tools and a small supply of fuel for ship lanterns. These rooms are fire hazardous and therefore must have access to an open deck.

Metal bulkheads of office premises are made of fire-resistant material. In addition, structurally these premises must always meet the highest fire safety requirements.

The design and location of office equipment must guarantee maximum ease of maintenance and the possibility of using general ship systems (fire extinguishing, irrigation, etc.).

The service premises also include the tiller compartment, which houses the steering gear. It is located in the stern.

Abstract on the topic:

Bridge ( maritime term)

Bridge- a fenced part of the deck of the upper tiers of superstructures and deckhouses or a separate platform. Bridges designed to accommodate control, observation or communication posts, as well as for transition from one superstructure to another.

Bridges They are distinguished by purpose - chassis, rangefinder, signal, searchlight, navigation and others.

By location bridges They are divided into bow and stern, according to the degree of protection from the effects of adverse environmental conditions - into open, closed and semi-closed.

The entire deck of the wheelhouse is called navigation bridge, and its open areas on the sides of the wheelhouse - wings of the navigation bridge. On ships intended for navigation at high latitudes, the wings of the navigation bridge and the wheelhouse are combined into one enclosed room for protection from low temperatures. Navigation bridge also called captain's(pilot bridge).

Navigation bridge called the roof of the wheelhouse and adjacent spaces. On the chassis and navigation bridges the main control posts of the ship are located.

Type of ship bridges are walkways, located above the upper deck and intended for transition from one side to another and for communication between superstructures. Longitudinal walkways installed on tankers that do not have any internal passages under upper deck and having a low freeboard height when fully loaded.

I'll tell you more about the ferry "Georg Ots".
I got there without any problems, first I bought a pass to enter the port, said that I needed to look at a new stroller at the temporary storage facility, then I went straight to the pier where Ots was standing, boarded the ship, called the captain's mate on watch, and honestly told him who I came and why. Once upon a time I also worked in the navy, and was subject to the Charter of service on ships navy, so we easily found a common language with the watchman. Therefore, not only did I get permission to photograph the ship, but I was also given a detailed tour of the ship.
Where does the ship begin? It’s hard to say, of course, maybe from the name, maybe from the stem, maybe from the captain. Let's start with the bridge. The correct name is command bridge or navigation bridge, but in the navy they call it bridge for short. Usually the bridge on a ship is located in the upper part of the superstructure, and the longer the ship, the higher they try to raise it to ensure the best better review. On modern ships, the bridge takes up the entire width of the ship, and even has wings protruding beyond the normal width. That's about the same as on "Georg Ots". Since the ship is intended for navigation in high latitudes, the wings of the bridge are made closed. For even better visibility, the bulkheads and windows are tilted forward and to the sides. The windows have wipers and heating, almost like a car. Above the bridge there is a navigation bridge; roughly speaking, this is the roof of an ordinary bridge. It contains the main means for controlling the vessel, such as the engine telegraph, rudder, a magnetic compass, searchlights, etc.

1. M/v "Georg Ots"

2. This is what the bridge looks like at the m/v "Georg Ots"

A navigation bridge with a mast, a white inscription on the deck - this is the identification number of the vessel, marked for easy identification of the vessel from the air. The mast contains GPS receivers, weather instruments, masts for radio stations of all bands, satellite phone receivers, rotating radar antennas, and navigation lights. The inscription “GEORG OTS” is necessary so that navigators from other ships with the help of binoculars can turn to navigator Ots, and not shout, “Hey, you, going on course 237, you will run over us right now.” Running lights are needed so that at night you can see that the ship is moving towards you with a certain side, red on the left, green on the right. In order for the navigator to be remembered better from the school, they are taught that they need to remember the “female genital organ”, from which they must independently isolate the letters “P” and “Z”, which correspond to “Right” and “Green”. Remembered for life.

On this bulkhead there are devices for communication with the shore; they replaced those bulky devices that previously occupied a separate room and required the presence of the head of the radio station and radio operators on the ship. Now the captain's assistants manage all this. In fact, all of these devices can replace a regular satellite phone, but here the most important thing is guaranteed communication and security, so something bulky but reliable is better. As far as I understand, devices for sending SOS signals are installed here. Previously, the so-called Cospas device usually hung on the bulkhead; in case of an emergency, it was necessary to turn it upside down and it would begin to give a signal. I don’t know whether these devices are still preserved due to the introduction of the global GMDSS system. Previously, communication with the shore from a flight looked like a special shamanic ritual, in certain time the radio operator called “Vladivostok-Radio” via a long-wave connection, then the girl operator in Vladivostok called the required phone, and when connected, connected the phone to the connection. The conversation took place openly throughout Pacific Ocean, looked something like “Vladivostok-Radio, Sergey will talk to you now,” “Hello, let’s do it,” “Hello, hello, wife, hello. Are you waiting for me???. Welcome!”, and from there “Yes, I’m waiting, welcome.” !", "How are the children? Welcome!", "What kind of children? What ship are you Sergei from? Welcome."

5. This nook is in charge of the third mate, here on nautical charts the ship's route is being plotted. There are signal flags on the shelves on top. They are used when it is necessary to send a signal to other vessels, but communication with them cannot be established via radio. For communication between ships and with coastal services there is its own duty channel. After communication on it, the parties select another channel for communication only between themselves and release the duty channel. To determine who exactly is calling you, there are signs on board the ship. English language. The fishermen also have their call sign written in capital letters. There is a ship's log on the table. The ship's log records: a list of the crew, the date of arrival at the port and departure from the port, the depth of water in the port and when leaving the sea, speed, course, wind force during the voyage, the names of the crew watch and navigator watch and their detailed report on all events that occurred during the flight.

6. Here there is a top-down converter that converts the data received from the log and gyrocompass into digital form and transmits it to navigation devices, another device that shows the speed taken from the log, a device that takes data from the gyrocompass, a plotter that records the movements of the vessel with using the GPS satellite system, the second picture shows a gyrocompass repeater showing the ship's heading. In fact, the operation of these devices can be replaced by a regular GPS receiver, but for the safety of navigation, all devices are installed at the factory. Without them or with non-functioning ones, the ship will not be released into the sea.

7. Autopilot, shows the angle of rotation and allows you to control the rotation of the ship's rudders. It can operate in automatic mode, keeping the vessel on a given course. Modern devices even take into account drift from side winds or waves.

8. There is also a device hanging here that automatically receives a weather map via satellite at certain intervals and prints it.

9. On the bulkheads hang diagrams of various ship life support systems.

10. Fire alarm system and control of fire partitions and extinguishing systems. Somewhere nearby there should be control panels for the hydraulic doors of the watertight partitions.

Vessels at sea disperse using a certain analogue of traffic regulations, the so-called COLREG-72, i.e. international rules to prevent collisions between ships at sea. Adopted in 1972 by an international convention and entered into force in 1977, they are binding on all persons operating a ship. The last changes were made to them in 2003.
In order to figure out what course ships around are following, ship radar is used. Using it, you can determine the speed and direction of movement of objects at sea, even those that are not yet visible visually. Based on this, the officer of the watch makes a decision on the need to maneuver or change the speed of the vessel. If the radars suddenly break down, a direction finder, a clock and a ruler are used to determine courses.

11. This is how it looks on the m/v "Georg Ots".

12. For safety, it is duplicated on the second side. It usually has its own separate antenna. In general, duplication of systems is common for the fleet, as they say, safety first.

13. Control devices for various searchlights, ship horns, navigation lights, lighting, steering gears, etc. are located here. I don’t know exactly, I didn’t look at it much.

14. Control telegraphs are located here power plant, adjustable pitch propellers, bow and stern thrusters, as well as communication with the central control station.

15. The controls are duplicated on each wing.

That’s all for today...if I was inaccurate somewhere, don’t blame me, I’m not “horned”, as they call navigators on a ship, tomorrow I’ll tell you about the interior of the ship, and then about the engine room.

The navigation bridge includes:

Wheelhouse;

Navigation bridge wings;

Upper navigation bridge;

Navigation post.

1.7.1 Wheelhouse

In the wheelhouse there are ship control posts. The equipment is installed so as to allow one person to operate the vessel. The shape, dimensions of the cabin and its glazing should provide the navigator with a maximum view close to 360 0 .

Boatmaster's chair

Sofa (allowed at the back wall)

Hangers

Shelves and hangers for documents and flags

The front walls of the cabin are inclined. The walls between the windows are 150 mm.

A sketch of the pilothouse is shown in Figure 1/17.

1.7.2 Navigation enclosure

To determine the ship's position and course with the help of navigation equipment, instruments and maps in modern wheelhouses, the navigation station in the wheelhouses is fenced off, which is located at the rear wall to the right of the control room. The navigator's station is equipped with a navigator's table with drawers for maps. The table is positioned so that the navigator faces the bow of the ship.

1.7.3 Upper navigation bridge and bridge wings

Speaking pipes, antennas and a searchlight are installed on the upper navigation bridge.

The navigation bridge wings are located behind the large wheelhouse. Dimensions provide observations along the side of the ship, bearings of coastal objects. Peloruses are installed on the wings.
