Today we will have a different video than usual, I will show the ship inside the superstructure up to the bridge deck, follow below quick explanation about the bridge, hope you enjoy with video, greetings from Brazil !!!

The ship’s bridge serves as a controlling and commanding station for the entire ship. We can control all the machinery, boiler, and ship’s navigation from the bridge. This provides a common platform for the ship’s alarming and controlling station for onboard machinery.

All systems and equipment must meet IMO standards and must be approved by the administration to be installed in the bridge. Electrical and electronic equipment shall be so installed that the electromagnetic interference does not affect proper functioning of navigation systems and equipment. Safety of navigation depends on proper, efficient, and timely use of these aids. All these aids must be checked from time to time for their performance and accuracy. Errors and deviations must be logged. All navigating officers must be familiar with their use.

The common activities carried out on bridge can be broadly grouped as:

Lookout and avoidance of collision.
Control of ship’s speed and direction.
Navigation and position fixing.
Monitoring weather and sea condition.
Communication – external and internal.

Ship’s Bridge Construction Features favorable for Lookouts
Lookout for traffic is maintained from the navigation bridge. During poor visibility and in restricted waters, additional lookout may be maintained form the forecastle or crow’s nest atop the forward mast.

The navigation bridge is situated on the uppermost deck with a clear view of the sea ahead and abeam. It is so constructed that the navigators get clear vision for 255o or more. From the conning position, vision should be from 112.5o port to 112.5o starboard. From the bridge wing the vision should be from 180o on the wing side to 45oon the other side. The ship’s side should be visible from the wings. View from the steering position should be 60o port to 60o stbd. Obstruction due to deck cranes, masts, etc. should not be more than 10o. Front windows should give clear view without reflections. Windows are inclined 10o-25o. Two clear view screens are provided in front windows for use when the view is obscured by rain.

Binoculars are used for long distance viewing in daytime when the weather is clear. At night or when the visibility is restricted, radar should be used for lookout. Range scale should be selected according to the traffic density, ship’s speed, and distance from the coast. Heading marker should be checked against the compass heading and the ships fore and aft line. It is advisable to use the radar in clear weather also, to check its effectiveness.

Ships more than 10,000 GT and above should have two radars including one operating on X band, 9 GHz frequency. They should have automatic radar plotting aid (ARPA). Smaller ships are fitted with automatic tracking aid (ATA) or electronics plotting aids (EPA).

Ship’s Speed
Every ship should have an indicator for the propeller speed and direction of rotation on the bridge. If the propeller is of controllable pitch, there should be indication of pitch also. On UMS ships, machinery can be controlled from the bridge.
In Integrated Bridge System (IBS), various operations such as passage execution, communications, machinery control, and safety and security are centrally monitored. Engines can be stopped in emergency. Overriding provisions are made in case of main engine.
A telegraph is provided on the bridge for communication with the engine room regarding engine speed and direction. Controls are tested before departure and the engine movements are recorded in bridge. The bridge telegraph may be connected to a teleprinter for automatic recording. Repeaters are provided on the bridge wings.
The speed log shows the ship’s speed in knots, and the distance indicator records distance covered in nautical miles. A calibration chart is provided; these readings should be verified by plotting the ship’s position on the charts.

Direction Controls
The ship’s direction is set by the use of the Standard Magnetic Compass, Steering Magnetic Compass, or Gyrocompass. There should be communication between the standard magnetic compass and the steering position. An efficient periscope with sufficient magnification and adjustability is provided for comfortable viewing of the standard compass by the helmsman. The steering compass must be compared with the standard compass at least once per watch and after every major alteration of course. Deviations are recorded on a card maintained on the bridge. The standard compass should be checked and adjusted when the deviation shows a marked change.
