14.13 Sources of energy

  14.13.1 There shall be available at all times, while the craft is at sea, a supply of electrical energy sufficient to operate the radio installations and to charge any batteries used as part of a reserve source of energy for the radio installations.

  14.13.2 Reserve and emergency sources of energy shall be provided on every craft to supply radio installations, for the purpose of conducting distress and safety radiocommunications, in the event of failure of the craft's main and emergency sources of electrical power. The reserve source of energy shall be capable of simultaneously operating the VHF radio installation required by 14.7.1.1 and, as appropriate for the sea area or sea areas for which the craft is equipped, either the MF radio installation required by 14.9.1.1, the MF/HF radio installation required by 14.10.2.1 or 14.11 or the ship earth station required by 14.10.1.1 and any of the additional loads mentioned in 14.13.5 and 14.13.8 for a period of at least 1 hour.

  14.13.3 The reserve source of energy shall be independent of the propelling power of the craft and the craft's electrical system.

  14.13.4 Where, in addition to the VHF radio installation, two or more of the other radio installations referred to in 14.13.2 can be connected to the reserve source or sources of energy, they shall be capable of simultaneously supplying, for the period specified in 14.13.2, the VHF radio installation and:

  • .1 all other radio installations which can be connected to the reserve source of energy at the same time; or

  • .2 whichever of the radio installations will consume the most power, if only one of the other radio installations can be connected to the reserve source of energy at the same time as the VHF radio installation.

  14.13.5 The reserve source of energy may be used to supply the electrical lighting required by 14.6.2.4.

  14.13.6 Where a reserve source of energy consists of a rechargeable accumulator battery or batteries:

  • .1 a means of automatically charging such batteries shall be provided which shall be capable of recharging them to minimum capacity requirements within 10 hours; and

  • .2 the capacity of the battery or batteries shall be checked, using an appropriate method,footnote at intervals not exceeding 12 months, when the craft is not at sea.

  14.13.7 The siting and installation of accumulator batteries which provide a reserve source of energy shall be such as to ensure:

  • .1 the highest degree of service;

  • .2 a reasonable lifetime;

  • .3 reasonable safety;

  • .4 that the battery temperatures remain within the manufacturer's specifications whether under charge or idle; and

  • .5 that when fully charged, the batteries will provide at least the minimum required hours of operation under all weather conditions.

  14.13.8 If an uninterrupted input of information from the craft's navigational or other equipment to a radio installation required by this chapter is needed to ensure its proper performance, including the navigation receiver referred to in 14.18, means shall be provided to ensure the continuous supply of such information in the event of failure of the craft's main or emergency source of electrical power.
