Part B Rules of Bar and Road

Section 1 Conduct of vessels in all conditions of visibility

Rule 4 Scope of application

The rules in this section apply in all conditions of visibility.

Rule 5 Standby

Every ship must always ensure an appropriate visual and hearing watch, using also all available means which are adapted to the existing circumstances and conditions, so as to enable a full appreciation of the Situation and risk of collision.

Rule 6 Security Speed

Every ship shall maintain at all times a safety speed such that it can take appropriate and effective measures to avoid collision and to stop at a distance appropriate to the existing circumstances and conditions.

In particular, the following factors must be taken into account in determining the speed of safety:

(a)
By all ships:
(i)
Visibility;
(ii)
Traffic density and, in particular, concentrations of fishing vessels or other vessels;
(iii)
The ship's ability to manoeuvre and, in particular, its stopping distance and qualities of rotoring under existing conditions;
(iv)
At night, the presence of a light background such as that created by coastal fires or a scattering of light from the ship's own lights;
(v)
The state of the wind, the sea and currents and the proximity of risks to navigation;

In addition, by ships using radar:
(i)
The characteristics, effectiveness and limits of use of radar equipment;
(ii)
Limitations resulting from the scale scale used on the radar;
(iii)
The effect of sea conditions, weather conditions and other sources of interference on radar detection;
(iv)
The fact that small vessels, ice and other floating objects may not be detected by radar at a sufficient distance;
(v)
The number, position and movement of vessels detected by the radar;
(vi)
The fact that it is possible to appreciate more precisely the visibility when the radar is used to determine the distance of the ships and other objects located in the vicinity.
Rule 7 Risk of collision

(a) Every ship shall use all available means which are adapted to the existing circumstances and conditions to determine whether there is a risk of collision. If there is any doubt as to the risk of collision, this risk must be considered to exist.

(b) If there is on board a functioning radar equipment, it shall be used appropriately using, in particular, long-range scanning in order to detect in advance a risk of collision, as well as to the radar or any other Equivalent systematic observation of detected objects.

(c) Inadequate information, including insufficient radar information, should be avoided.

(d) The assessment of a collision risk must take into account the following considerations:

(i)
There is a risk of collision if the compass bearing of a ship approaching does not change appreciably;
(ii)
Such a risk can sometimes exist even if there is significant variation in recovery, particularly when approaching a very large vessel, a trailer train or a short-distance vessel.
Rule 8 Manoeuvre to avoid collisions

(a) Any manoeuvre undertaken to avoid collision shall, if circumstances permit, be carried out frankly, in good time and in accordance with good maritime practice.

(b) Any change of course or speed, or both, to avoid collision shall, if circumstances permit, be of sufficient importance to be immediately perceived by any ship observing it visually or by radar; an estate Slight changes of course or speed, or both, is to be avoided.

(c) If the ship has sufficient space, the change of course on its own can be the most effective manoeuvre to avoid being in a very close situation, provided that this manoeuvre is made widely on time, that it is straightforward and It does not result in another very close situation.

(d) manoeuvres to avoid collision with another vessel shall be such as to allow sufficient distance to be taken. The efficiency of the manoeuvres must be carefully controlled until the other ship is finally parted and clear.

(e) If this is necessary to avoid collision or to allow more time to assess the situation, a ship must reduce its speed or break its thunder by stopping its propellant or by reversing it by means of this device.

(f) 1 (i)
A ship which, under any of these Rules, is required not to interfere with the passage of another ship or to permit its free passage shall, where circumstances so require, delay without delay in order to leave sufficient Place the other ship to allow its free passage.
(ii)
A ship which is required not to interfere with the passage of another ship or to permit its free passage shall not be exempt from this obligation if it approaches the other ship in such a way that there is a risk of collision and shall, when carrying out Manoeuvring, taking due account of manoeuvres that may be required under the rules of this Part.
(iii)
A ship whose passage shall not be hindered shall remain fully obliged to comply with the rules of this Part when the two vessels are approaching each other in such a way that there is a risk of collision.

(e)
(i) In a narrow channel or an access road, where an exceedance can only be carried out if the vessel is manoeuvred to allow the other ship to exceed it safely, the vessel intending to overtake shall make known its Intention by issuing the appropriate sound signal prescribed by Rule 34 (c) (i). The catch-up vessel shall, if it agrees, make the appropriate signal prescribed by Rule 34 (c) (ii) and operate in such a way as to allow for a safe overrun. If it is in doubt, it may transmit the sound signals prescribed by Rule 34 (d);
(ii)
This Rule shall not exempt the ship which catches up from the obligation to comply with the provisions of Rule 13.

Annex III 1

Technical characteristics of sound-signalling equipment

1. Sifflets

(a) Frequency and noise range

The basic frequency of the signal shall be between 70 and 700 Hz.

The sound scope of the signal of a whistle is determined by the frequencies, which may include the fundamental frequency, one or more higher frequencies, located between 180 and 700 Hz (± 1 per cent) and providing the pressure levels Acoustics specified in section 1 (c) below.

(b) Basic frequency limits

In order to ensure a wide variety in whistling characteristics, the fundamental frequency of a whistle must be within the following limits:

(i)
Between 70 and 200 Hz on board a ship equal to or greater than 200 metres;
(ii)
Between 130 and 350 Hz on board a ship equal to or greater than 75 metres, but less than 200 metres;
(iii)
Between 250 and 700 Hz on board a ship less than 75 metres in length.

(c) Signal intensity and sound range

A whistle installed on a ship shall ensure in the direction of its maximum intensity, at a distance of 1 metre and in at least one band of one-third octave located in the frequency range 180 to 700 Hz (± 1 %), a pressure level At least equal to the appropriate value of the table below.

The sound scope was indicated in this table for information purposes. It corresponds approximately to the distance at which a whistle can be heard on its axis before with a 90 per cent probability in calm air, on board a ship where the level of background noise at the listening stations is average (68 dB in The octave band centred on the frequency 250 Hz and 63 dB in the octave band centred on 500 Hz).

In practice, the distance to which a whistle can be heard is highly variable and depends heavily on weather conditions. The values indicated may be considered characteristic but, in the case of a violent wind or when the noise level at the listening posts is high, the sound scope may be very small.

(d) directional characteristics

In all directions of the horizontal plane within an area of ± 45 degrees with respect to the axis, the sound pressure level of a directional whistle shall not be more than 4 dB below the sound pressure level prescribed on Axis. In any other direction of the horizontal plane, the sound pressure level shall not be more than 10 dB below the sound pressure level prescribed on the axis so that the range in any direction is equal to half the Less the scope on the axis. The sound pressure level shall be measured in the band of one-third octave which produces the sound range.

(e) Location of whistles

When a directional whistle is used as a single whistle on a ship, it must be installed in such a way as to produce its maximum intensity towards the front of the ship.

The whistles must be placed as high as possible on board the ship to reduce the interception, by obstacles, of the sounds emitted and to minimize the risk of hearing problems among the crew members. The sound pressure level of the ship's own signal shall not exceed 110 dB (A) at the listening posts and should not exceed 100 dB (A) as far as possible.

F) Installation of several whistles

If whistles are installed more than 100 metres away, they must be mounted in such a way that they are not activated simultaneously.

(g) Piping set

If, due to the presence of obstacles, the acoustic field of a single whistle or one of the whistles mentioned in par. (f) above may present an area where the acoustic level of the signal is substantially reduced, it is recommended to use a set of whistles installed in such a way as to avoid this reduction of the acoustic level. For the purposes of the Rules, a set of whistles is considered a unique whistle. The whistle of such a set shall not be more than 100 metres away from each other and shall be mounted so that it can be operated simultaneously. Their frequencies shall differ from each other by at least 10 Hz.

2. Bell or gong

(a) Signal intensity

A bell, gong or any other device having similar acoustic characteristics shall ensure an acoustic pressure level of at least 110 dB at a distance of 1 metre from that equipment.

(b) Construction

The bells and gongs must be constructed of a corrosion-resistant material designed to emit a clear sound. The diameter of the bell opening shall not be less than 300 millimetres on vessels equal to or greater than 20 metres and 200 millimetres on vessels of length equal to or greater than 12 metres but less than 20 metres. Where possible, it is recommended that a mechanical control bell be installed so as to ensure a constant force of impact, but it must be possible to activate it by hand. The mass of the fly shall not be less than 3 per cent of the mass of the bell.

3. Licensing

The construction and operation of the sound-signalling equipment and its installation on board the ship shall be deemed satisfactory by the competent authority of the State whose vessel is authorised to fly the flag.
