(L.N. 533 of 1994)(3) The reserve source or sources of energy need not supply independent HF and MF radio installations at the same time. (4) The reserve source or sources of energy shall be independent of the propelling power of the ship and the ship's electrical system. (5) Where, in addition to the VHF radio installation, 2 or more of the other radio installations, referred to in subsection (2), can be connected to the reserve source or sources of energy, they shall be capable of simultaneously supplying, for the period specified, as appropriate, in subsection (2)(a) or (b), the VHF radio installation and - (L.N. 533 of 1994) (a) all other radio installations which can be connected to the reserve source or sources of energy at the same time; or (b) whichever of the other radio installations will consume the most power, if only one of the other radio installations can be connected to the reserve source or sources of energy at the same time as the VHF radio installation.(6) The reserve source or sources of energy may be used to supply the electrical lighting required by section 6(2)(d). (7) Where a reserve source of energy consists of rechargeable accumulator batteries- (a) 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 (b) the capacity of the batteries shall be checked, using an appropriate method, at intervals not exceeding 12 months, when the ship is not engaged on voyages.(8) The siting and installation of accumulator batteries which provide a reserve source of energy shall be such as to ensure- (a) the highest degree of service; (b) a reasonable lifetime; (c) reasonable safety; (d) that battery temperatures remain within the manufacturer's specifications whether under charge or idle; and (e) that when fully charged, the batteries will provide at least the minimum required hours of operation under all weather conditions.(9) If an uninterrupted input of information from the ship's navigational or other equipment to a radio installation required by this Regulation is needed to ensure its proper performance, means shall be provided to ensure the continuous supply of such information in the event of failure of the ship's main or emergency source of electrical power. (10) For the purpose of calculating the required capacity of the reserve source of energy, the total current used shall be calculated in accordance with the method specified in Schedule 1. (Enacted 1992) Cap 369AR s 14 Performance standards Every equipment required to be provided under this Regulation- (a) shall conform to performance standards adopted by the International Maritime Organization which shall be specifications specified in Schedule 2; and (b) shall, in the case of equipment provided on Hong Kong ships, in addition, conform to appropriate performance specifications issued by the Telecommunications Authority which shall be specifications specified in Schedule 2. (Enacted 1992) Cap 369AR s 15 Serviceability and maintenance requirements (1) Every equipment required to be provided under this Regulation shall be so designed that the main units can be replaced readily, without elaborate recalibration or readjustment. (2) Where applicable, the equipment shall be so constructed and installed that it is readily accessible for inspection and on-board maintenance purposes. (3) Adequate information to the satisfaction of the Director shall be provided on every ship to enable the equipment to be properly operated and maintained. (4) Adequate tools and spares to the satisfaction of the Director shall be provided on every ship to enable the equipment to be maintained and the Director may specify in a Merchant Shipping Notice the tools and spares to be provided on Hong Kong ships. (5) Every radio equipment required to be provided under this Regulation shall be maintained to provide the availability of the functional requirements specified in section 5 and to meet the performance specifications specified in Schedule 2. (6) On ships engaged on voyages in sea areas A1 and A2, the availability shall be ensured by using at least one of the following methods specified in Schedule 3, that is to say- |
