Paragraph 2.3.4 |
All navigation instruments and devices (with the exception of the heading or trajectory control system) , designed to be powered by electric energy, must be powered by individual feeders from one common shield of navigation equipment. The ship heading control system and the ship's trajectory control system must be powered in accordance with 5.5.14 of Part XI “Electrical Equipment” of the Rules for the Classification and Construction of Marine Ships. ” |
All navigation instruments and devices (with the exception of the gyroscopic compass and the heading or trajectory control system) , designed to be powered by electric energy, must be powered by separate feeders from one common shield of navigation equipment. The gyro compass must be powered in accordance with 3.7.2.3 . The ship heading control system and the ship's trajectory control system must be powered in accordance with 5.5.14 of Part XI “Electrical Equipment” of the Rules for the Classification and Construction of Marine Ships. ” |
Paragraphs 3.7.2.3 and 3.7.2.4 are deleted. The numbering of paragraphs 3.7.2.5 - 3.7.2.12 is changed to 3.7.2.3 - 3.7.2.10, respectively. |
Excluded: 3.7.2.3 The gyrocompass must receive power from the main switchboard and the emergency switchboard through two independent feeders. 3.7.2.4 Automatic switching of the gyrocompass power supply from the main switchboard to the switchboard of the emergency power station (in the presence of an emergency diesel generator) should be provided in case of a power failure (see also part XI “Electrical equipment” of the Rules for the Classification and Construction of Ships) . |

Part V, new paragraph 3.7.2.10 |
The renumbered paragraph 3.7.2.10 (existing 3.7.2.12) is replaced by the following text: “3.7.2.10 The requirements of 3.5.1.4 do not apply to ships of less than 300 gross tonnage. The implementation of requirements 3.5.1.1 - 3.5.1.3 is recommended. ”. |
Ships of less than 300 gross tonnage are not subject to the requirements of 3.5.1.4. It is recommended that the requirements of 3.5.1.1 _ 3.5.1.3, 3.7.2.3 be met . ". |
Paragraph 3.7.3.4 | The clinkers of the primary converters should be placed in a special shaft that meets the requirements of 3.6. On fishing vessels, primary transducers may be installed in a box keel . ” | The clinkers of the primary converters should be placed in a special shaft that meets the requirements of 3.6. |
Paragraph 3.7.4.6 |
It is allowed to install echo sounder vibrators in cofferdams of cargo and fuel tanks, in the double bottom compartments and ventilated tunnels located under the cargo compartments of oil loading vessels, provided they are placed in a special gas-tight partition, which is a hull structure (see also 3.8.3 of this part of the Rules and 2.2 .2.9 of part XI “Electrical equipment” of the Rules for the classification and construction of marine vessels). Installation of supply cables should be made in gas-tight steel pipes. On fishing vessels, the installation of vibrators of echo sounders in a box keel is allowed. "The vibrators installed in these rooms must be of such a design that does not require maintenance." |
