Cap 415C reg 8 Miscellaneous tonnages; segregated ballast oil tankers and deck cargoes (1) Where segregated ballast tanks complying with regulation 13 of Annex 1 of International Convention for the Prevention of Pollution from Ships, 1973 as modified by the Protocol of 1978 relating to that Convention are provided in oil tankers, an entry may be made on the International Tonnage Certificate (1969) indicating the total tonnage of these tanks. The tonnage of such segregated ballast tanks shall be calculated according to the following formula: K1 × Vb where: K1 = 0.2 + 0.02 log10 V or as specified in Schedule 3 V = the total volume of all enclosed spaces of the ship in cubic metres Vb = the total volume of segregated ballast tanks in cubic metres measured in accordance with regulation 5.(2) Where cargo is carried in any uncovered space on deck the tonnage of the space so occupied to be taken into account for the purposes of determining the dues payable where goods are carried in spaces not forming part of the gross or net tonnages, shall be determined by the formula: (74 of 1990 Sch. 5) Deck Cargo Tonnage = 0.353 (mean length x mean breadth x mean height). Cap 415C reg 9 Issue of certificates The Certifying Authority shall, upon receipt of the appropriate fee, issue to the owner of every ship registered in Hong Kong, the tonnages of which have been ascertained in accordance with regulations 6 and 7 of these regulations, an International Tonnage Certificate (1969) in the form set out in Schedule 4 to these regulations, certifying the tonnages of the ship and containing the following particulars- (a) the name, port of registry and official number of the ship; (b) its length, breadth and moulded depth; (c) its gross and net tonnages; (d) the date on which the keel was laid or the ship was at a similar stage of construction or date on which the ship underwent alterations or modifications of a major character. Cap 415C reg 10 Cancellation of certificates (1) Where alterations are made in the arrangement, construction, capacity, use of spaces, total number of passengers the ship is permitted to carry under the terms of the ship's passenger certificate, assigned load line, or permitted draught of the ship such as would cause an increase in the gross or net tonnage, the existing International Tonnage Certificate (1969) shall cease to be valid and shall be delivered up to and cancelled by the Certifying Authority. (2) When a ship is transferred from the Hong Kong Register the International Tonnage Certificate (1969) shall cease to be valid except when the transfer is to the Administration of a state which is a Contracting Government in which case the certificate may remain in force for a period not exceeding 3 months or until the new Administration issues another International Tonnage Certificate (1969) whichever is the earlier. The Certifying Authority shall transmit to the Administration of that Government as soon as possible after the transfer has taken place a copy of the certificate carried by the ship at the time of transfer and a copy of the relevant tonnage calculations. Cap 415C reg 11 Change of net tonnage necessitating issue of certificates (1) When alterations in the values of V, Vc, d, N1 or N2 as defined in regulations 6 and 7 result in an increase in the net tonnage a new International Tonnage Certificate (1969) incorporating the increased net tonnage shall be issued. (2) In the case of a passenger ship assigned subdivision load lines in accordance with the Merchant Shipping (Safety) (Passenger Ship Construction) (Ships Built Before 1 September 1984) Regulations (Cap 369 sub. leg.) or the Merchant Shipping (Safety) (Passenger Ship Construction and Survey) (Ships Built On or After 1 September 1984) Regulations (Cap 369 sub. leg.) (as appropriate) and load lines in accordance with the Load Line Rules only one net tonnage shall be applied. Where the draught corresponding to the Summer Load Line differs from that corresponding to the deepest subdivision load line the net tonnage shall be the greater of the two values determined in accordance with regulation 7 by applying the differing draughts. (64 of 1999 s. 3) (3) (a) Subject to sub-paragraph (b) below, where alterations in the values of V, Vc, d, N1 or N2 as defined in regulations 6 and 7, or changes in the position of the load lines result in a decrease in the net tonnage, a new International Tonnage Certificate (1969) incorporating the decreased net tonnage shall not be issued until 12 months have elapsed from the date on which the current certificate was issued. |
