DIVISION OF SHIPS TO GROUPS

2.1.1 For the purposes of this Part of the Rules, all self-propelled vessels are divided into groups of gross tonnage (see Table 2.2.1).

COMPOSITION OF NAVIGATION EQUIPMENT

2.2.1 The composition of navigational instruments, devices and instruments that are to be installed on a ship or by which a vessel is to be equipped is determined depending on its gross tonnage, taking into account the areas of navigation and destination of the vessel in accordance with Table. 2.2.1.

The definitions of the navigation areas are given in 1.2 of Part I of the "Regulations on Surveys".

2.2.2 In addition to the requirement 2.2. 1 it is recommended to equip vessels:

. 1 by a system of unified time;

. 2 integrated navigation system (ships of gross tonnage more than 10000);

. 3 by a speed meter (ships with a nasal arrangement of the navigation bridge, as well as vessels equipped with an integrated navigation system);

. 4 radio beacon installation (vessels with helicopter support);

. 5 hydro-meteorological complex (vessels with a gross tonnage of 300 0 and more).

2.2.3 The composition of navigation equipment of vessels of a special design, not specified in the Rules for certain types of vessels, is in each case subject to special consideration by the Register.

All vessels with additional signs in the icebreaker symbol 6 - Icebreaker 9 (icebreakers), РС1 -РС7 (ships of the polar classes IACS) should be equipped with the following equipment, taking into account requirement 2.2.1:

a distance course transmission device (based on the Global Navigation Satellite System (GNSS));

the equipment of the universal automatic identification system (AIS);

a lag providing the measurement of speed and distance traveled relative to the ground (it is allowed to use a separate GPS receiver, GPS, GLONASS or GPS / GLONASS) to measure and display the speed and distance traveled relative to the ground;

echo sounder independent of the echo sounder installed in accordance with Table. 2.2.1;

radar station operating in the 3 GHz band (wavelength - 1 0 cm);

a means of displaying navigation information (multifunction display);

separate indicators of the angular position of the rudder for each of the independently controlled rudders;

Receiving equipment providing information ice maps and weather maps;

a means of visualizing ice information (ice conditions).

2.2.4 Navigation equipment required in accordance with Table. 2.2.1., May be replaced by another, newly invented, developed or upgraded, provided that it is equivalent in purpose, has the required or better performance and technical characteristics and is approved by the Register.

2.2.5 Navigation equipment not provided for in this part of the Rules may be admitted to the vessel as an additional one provided that its placement and operation will not cause difficulties in working with the main navigational instruments, affect their indications and reduce the safety of navigation. Navigation equipment installed on the vessel in addition to the basic equipment provided in Table. 2.2.1, must be approved by the Register of type and must meet the operational and technical requirements for the main equipment.

2.2.6 If an absolute lag is provided on the vessel, it must meet the requirements of 5.4.

ECDIS REQUIREMENTS

5.15.90 Relevant duplicating facilities should be provided to ensure navigational safety of the vessel's navigation in the event of an ECDIS failure.

Such funds should:

. 1 to assume the functions of ECDIS so that when the system fails the situation does not grow into a critical one;

.2 after the failure of ECDIS to ensure a timely transition to a backup system without loss of cartographic information and to ensure navigation safety of the vessel's voyage for the rest of the voyage.

5.15.9 1 The duplication facility shall display in graphic (cartographic) form the relevant information on the hydrographic and geographical situation necessary for navigational safety of navigation.

5.15.92 The duplication facility shall provide the ability to perform pre-installation, including the following:

. 1 transfer of the preliminary gasket, initially performed on ECDIS;

2 Making corrections in the preliminary gasket manually or transferring it from the gasket device.

5.15.93 Means should ensure duplication assume the functions of executive performance gaskets, initially performed on the ECDIS, providing at least the following functions:
. 1 gasket on the map of the location of your own ship automatically or manually;

.2 removal of courses, distances and bearings from the map;

.3 mapping of the planned path;

.4 displaying time stamps on the track line;

.5 mapping the required number of points, bearing lines, distance markers, etc.

5.15.94 If the duplication facility is an electronic device, then on its own map information display means, information that is at least equivalent to that which is to be displayed on the standard ECDIS display means shall be provided.

5.15.95 The cartographic information to be used in the duplicating facility must be the latest edition, updated with an official proof, published by the government or, at its request, by the hydrographic service or other appropriate government agency and must comply with IHO standards.

The possibility of changing ENC content should be excluded.

The source of the issuance of the map or map data, as well as the release date, should be indicated.

5.15.96 The cartographic information displayed by the ECDIS duplication tool shall be updated with the update for the forthcoming voyage.

5.15.97 If an electronic display tool is used in the ECDIS duplication facility, it shall provide an indication if:

. 1 information is displayed on a larger scale than the scale that is contained in the database;

.2 the location of your own ship is overlapped by a map of a larger scale than the display scale used.

5.15.98 If the image on the electronic display device of the ECDIS duplicating system is supplemented with radar and other navigation information, then all relevant operational and technical requirements of this chapter must be met. If an electronic ECDIS duplicator is used, the display mode and the display of the next screen area must meet the requirements of 5.15.40 to 5.15.44.

5.15.99 The ECDIS duplication facility should provide a record of the route of the own ship, including the position of the vessel and the corresponding time stamps.

5.15.100 The ECDIS duplication tool shall ensure reliable operation under the same environmental conditions as the main system.

5.15.10 1 The accuracy of all calculations must meet the requirements of 5.15.80 - 5.15.82.

5.15.102 The electronic ECDIS duplication tool shall provide appropriate alarms or indications when a duplication remedy is detected.

5.15.103 The electronic ECDIS duplication tool should be designed in accordance with ergonomic principles relating to ECDIS.

5.15.104 In the ECDIS electronic duplicator, the colors and symbols recommended by the IHO should be used to display the cartographic information, and the effective size of the displayed map must not be less than 25 0 x 25 0 mm or a diameter of at least 25 0 mm.

5.15.10 5 The electrical power of the ECDIS duplication tool shall be independent of the main system.

5.15.106 The electronic ECDIS duplication tool should be interfaced with systems that enable continuous positioning of the ship and do not create interference and distortions for the operation of other associated equipment.

5.15.107 If a radar image is applied as a duplication element to certain parts of the mapping information, the radar station shall meet the requirements of 5.7.
