[接上页] (g) be provided with a reliable emergency light consisting of an electric lamp, operated from the reserve source of electrical energy, permanently arranged so as to provide satisfactory illumination of the operating controls of the main and reserve radiotelegraph installations and of the clock required by paragraph (f) and controlled by two-way switches placed near the main entrance to the radiotelegraph operating room and at the radiotelegraph operating position. These switches shall be clearly labelled to indicate their purpose; (h) be provided with an electric inspection lamp complete with a flexible lead of adequate length and operated from the reserve source of electrical energy. A serviceable flashlight shall also be provided and kept in the radiotelegraph operating room; (i) be provided with a chair capable of being fixed at the radiotelegraph operating position; (j) on new Hong Kong ships, be provided with alternative means of exit and be of sufficient size to enable the equipment installed in the room to be properly maintained. (Enacted 1991) Cap 369AP reg 24 Provision of antennae (1) Every radiotelegraph ship to which these regulations apply shall be provided and fitted with suitable transmitting and receiving antennae and insulators. Where wire antennae are suspended between supports liable to whipping, they shall be protected against breakage. (2) The performance of the radiotelegraph installation required by these regulations shall not be adversely affected by the connection of any other equipment to the antennae. (3) A main transmitting antenna and a reserve transmitting antenna shall be fitted, provided that the Director may exempt any ship from the provision of a reserve transmitting antenna if he is satisfied that the fitting of such an antenna is impracticable or unreasonable. Any ship so exempted shall carry- (a) if the main transmitting antenna is a supported wire antenna, a spare antenna completely assembled for rapid replacement of the main antenna; (b) if the main transmitting antenna is not a supported wire antenna, a spare antenna of similar electrical characteristics, complete with the necessary materials and other means to enable it to be rapidly erected while the ship is at sea.(4) Every radiotelegraph ship shall also be provided with sufficient antenna wire, insulators and other means necessary to enable a suitable transmitting antenna to be erected. (5) The main transmitting antenna and the reserve transmitting antenna (if any) shall, where practicable, be so rigged that damage to the one will not affect the efficiency of the other. (6) Means shall be provided for quickly connecting- (a) the main transmitting antenna and the reserve transmitting antenna (if any) to the main transmitter and, separately, to the reserve transmitter (if any); and (b) the main and reserve receivers to any antenna with which they may need to be used.(7) Suitable antennae shall be provided for, and shall normally be connected to, the radiotelegraph auto alarm and the radiotelephone distress frequency watch receiver or the radiotelephone auto alarm. (Enacted 1991) Cap 369AP reg 25 Range of radiotelegraph transmitter (1) The main transmitter and the reserve transmitter (if any) shall, when connected to the main antenna, have a minimum normal range as specified in the Table below, that is to say, they must be capable of transmitting clearly perceptible signals from ship to ship by day and under normal conditions and circumstances over the ranges there specified- TABLE Minimum normal range in miles Main transmitter Reserve transmitter All passenger ships, and cargo ships of 1600 tons and upwards .................................................................... 150 100 Cargo ships below 1600 tons ........................................... 100 75 (2) The range of a radiotelegraph transmitter for the purposes of these regulations shall normally be determined by calculation of the metre-amperes. Where an antenna arrangement causes difficulty in determining the range of a transmitter by calculation, the range shall be determined by test. (Enacted 1991) Cap 369AP reg 26 Supply of electrical energy (1) While a radiotelegraph ship is at sea and at all reasonable times when she is in port there shall be available a supply of electrical energy sufficient to operate the main radiotelegraph installation over the normal range required by regulation 25 as well as for the purpose of charging any batteries forming part of the radiotelegraph installation. (2) The reserve installation shall be provided with a source of energy independent of the propelling power of the ship and of the ship's main electrical system. Means for bringing the reserve source of energy into immediate operation shall be provided and shall be situated in a radiotelegraph operating room or, if this is not possible, close thereto, and be provided with an electric lamp for illumination. (3) The reserve source of energy- |
