Systems and devices
All vessels must be equipped with a closed wastewater system that includes a device for biological cleaning or physicochemical treatment and sterilization of wastewater. A wastewater collection tank must be provided with capacity sufficient for 30 days' navigation.
* The ballast tanks adjacent to the outer side above the load waterline, including the tanks in the vessel's double side, must be supplied with a heating system to prevent freezing.
Navigational and communications equipment
The following equipment must be installed aboard ships, together with standard means of navigation.
* A gyrocompass with repeaters at all control stations, fathometer and direction finder
* Vessels with gross tonnage of more than 1,600t and all passenger ships must be provided with two radar sets that operate independently of each other. It is recommended that one set have a wavelength of 10cm. Vessels with lesser tonnage must have a single radar set with wavelength of 3cm.
* Radio or satellite navigation system that enables position of the ship to be determined to within at least 100m with 95% probability
A radio log or an acoustic log for measuring ship speed, with a system of transmitters and receivers protected from possible collision with ice
* In addition to ordinary means of radio communications, all vessels must be provided with the following equipment:
- Onboard ground station for satellite communications
- Navigational warnings receiver (NAVTEX)
- Satellite emergency radio buoy (satellite EPIRB)
- Instruments for sound recording and reception of facsimiles, including receipt of maps of hydrometeorological information
- VHF station for communications with airplanes, helicopters and vessels traveling in a convoy and operating at a frequency of 122.5MHz
Provisions and emergency facilities
* At the start of a voyage along the NSR, each ship must be provided with a double store of fuel and lubricants. In case of transit navigation along the NSR, stores of fuel and lubricants must be sufficient for 30 days. Stores of provisions and fresh water (taking into account replenishment from a distilling plant) and all other types of ship provisions must be sufficient for at least 60 days.
* Spare parts, instruments and firefighting equipment must be available onboard the ship and conform to the rules of Russia's or other classification societies. In addition, the set of spare parts must include a screw propeller or, in the case of propellers with detachable blades, two spare blades for each propeller.
* In addition to the spare parts required by Russia's or other classification societies, an assortment of other items are required, such as pulleys and notch blocks for changing blades and propellers, portable gas-welding equipment for welding and cutting, searchlights, portable electric submersible pump with a set of hoses, sets of warm clothing and hydrothermal suits.
4.3.4 Navigational requirements
Crew
* The size of the crew for navigation in ice must be large enough to guarantee a three-shift watch.
* The ship master (captain) or a person substituting for him on a bridge watch must possess the minimum level of knowledge of navigation in ice: experience of steering vessels under ice conditions along the NSR for not less than 15 days. In the absence of such experience, the presence of an ice pilot aboard the vessel is compulsory.
