[接上页] (Enacted 1992) Cap 369AT s 7 External openings PART V EXTERNAL OPENINGS (1) All external openings leading to compartments assumed intact in the damage analysis, which are below the final damage waterline, shall be watertight. (2) External openings required to be watertight in accordance with subsection (1) shall be of sufficient strength and, except for cargo hatch covers, shall be fitted with indicators on the bridge. (3) Openings in the shell plating below the deck limiting the vertical extent of damage shall be kept permanently closed while at sea. Should any of these openings be accessible during the voyage, they shall be fitted with a device which prevents unauthorized opening. (4) Notwithstanding the requirements of subsection (3), the Certifying Authority may authorize that particular doors may be opened at the discretion of the master, if necessary for the operation of the ship and provided that the safety of the ship is not impaired. (5) Other closing appliances which are kept permanently closed at sea to ensure the watertight integrity of external openings shall be provided with a notice affixed to each appliance to the effect that it is to be kept closed. Manholes fitted with closely bolted covers need not be so marked. (6) Where a ship does not conform to any requirement in subsection (1), (2), (3) or (5), the owner and master of the ship each commits an offence and is liable to a fine of $20000 and to imprisonment for 2 years. (Enacted 1992) Cap 369AT s 8 Survey before issue of a cargo ship safety construction certificate PART VI MISCELLANEOUS A surveyor carrying out a survey of a ship for the purpose of issuing a cargo ship safety construction certificate shall, before issuing such certificate, satisfy himself that the requirements in this Regulation have been complied with to an extent which is satisfactory having regard to the service for which the ship is intended and the period for which the certificate is to be issued. (Enacted 1992) Cap 369AT s 9 Maintenance (1) Every ship shall be maintained in such condition so as to conform to this Regulation and the structure of the ship shall not be altered in any manner without the approval of the Certifying Authority. (2) Where a ship is not maintained as required under subsection (1) or an alteration is made to the structure of the ship without the approval of the Certifying Authority in contravention of that subsection, the owner and master of the ship each commits an offence and is liable to a fine of $20000 and to imprisonment for 2 years. (Enacted 1992) Cap 369AT s 10 Equivalents Where this Regulation requires the compliance with a particular requirement, the Director may, in relation to a particular ship or a class of ships, accept or permit an alternative arrangement as compliance with such requirement, where he is satisfied by trial or otherwise, that such arrangement is at least as effective for the purpose of ensuring the safety of the ship as compliance with such requirement would have been. (Enacted 1992) Cap 369AT s 11 Amendment of Schedule The Director may- (a) by notice published in the Gazette amend the Schedule; and (b) issue instructions, directions or codes of practice providing practical guidance with respect to specifications, standards or requirements specified in this Regulation. (Enacted 1992) Cap 369AT SCHEDULE [sections 4(1), 5(1) & 11] PART I REQUIRED SUBDIVISION INDEX "R" 1. This Schedule is intended to provide ships with a minimum standard of subdivision. 2. The degree of subdivision to be provided shall be determined by the required subdivision index "R", as follows- (a) for ships over 100 metres in Ls:R = (0.002 + 0.0009Ls)1/3, where "Ls" is in metres; and (b) for ships of 80 metres in Ls and upwards but not exceeding 100 metres in Ls:Ls Ro R = 1 - [1/(1 + ------.------ )], 100 1-Ro where "Ro" is the value R as calculated in accordance with the formula in subparagraph (a). (L.N. 99 of 1999) PART II ATTAINED SUBDIVISION INDEX "A" 1. The attained subdivision index "A", calculated in accordance with this Part, shall not be less than the required subdivision index "R", calculated in accordance with Part I. 2. The attained subdivision index "A" shall be calculated for the ship by the following formula- A=∑pisi where- "i" represents each compartment or group of compartments under consideration; "pi" accounts for the probability that only the compartment or group of compartments under consideration may be flooded, disregarding any horizontal subdivision; "si" accounts for the probability of survival after flooding the compartment or group of compartments under consideration, including the effects of any horizontal subdivision. 3. In calculating "A", level trim shall be used. 4. This summation covers only those cases of flooding which contribute to the value of the attained subdivision index "A". 5. The summation indicated by the above formula shall be taken over the ship's length for all cases of flooding in which a single compartment or 2 or more adjacent compartments are involved. |
