MERCHANT SHIPPING 1 These Regulations may be cited as the Merchant Shipping (Cargo Ship Construction) (Amendment) Regulations 1999 and shall come into force on 5th April 1999. 2 The Merchant Shipping (Cargo Ship Construction) Regulations 1997 shall be amended as follows. 3 In regulation 4(c)(i) before the words “have prevented”, the word “not” shall be inserted. 4 After regulation 12 the following new regulation shall be inserted: Openings in the shell plating below the freeboard deck Requirements for ships constructed on or after 1st July 1998 12A 1 The number of sidescuttles, scuppers, sanitary discharges and other openings in the shell plating below the freeboard deck shall be the minimum which is compatible with the design and proper working of the ship. 2 The arrangement and efficiency of the means for closing every such opening below the freeboard deck shall be consistent with its intended purpose and shall be such as will ensure watertightness. 3 The design and arrangements of openings in the shell plating below the freeboard deck shall be in accordance with the specifications set out in Schedule 14 in Merchant Shipping Notice MSN 1671 (M) (Amended) . . 5 1 In Part III, in the heading to the Part, for “100” there shall be substituted “80”. 2 In regulation 14: a after “1992” there shall be inserted “and to every ship of 80 metres or over in subdivision length constructed on or after 1st July 1998,”; b at the end of sub-paragraph (g) “or” shall be inserted; c at the end of sub-paragraph (h) “or” shall be omitted; and d sub-paragraph (i) shall be omitted. 6 In regulation 15(2), for “M.1476 (M)” there shall be substituted “M.1715 (M)”. 7 In regulation 16(3), for “M.1476 (M)” there shall be substituted “M.1715 (M)”. 8 In regulation 22: a for the title there shall be substituted “ Location and separation of spaces ”; b for paragraph (1) the following shall be substituted: 1 a Machinery spaces shall be positioned: i aft of cargo tanks and slop tanks and shall be separated from them by a cofferdam, cargo pump-room, oil fuel bunker tank or permanent ballast tank; and ii aft of such cofferdam or cargo pump-room except that the lower part of a cargo pump-room may be recessed into a machinery space of Category A in order to accommodate pumps subject to the crown of the recess being not more than one third of the moulded depth above the keel. In the case of a ship not exceeding 25,000 tonnes deadweight where a recess of such height is not practicable for reasons of access and arrangement of piping, the recess may be increased to a height not exceeding one half of the moulded depth above the keel. b Pump-rooms, other than cargo pump-rooms, containing pumps and fittings for ballasting spaces adjacent to cargo tanks and slop tanks and pumps and fittings for oil fuel transfer may be considered equivalent to a cargo pump-room for the purpose of this regulation on condition that the fire protection arrangements and fire extinguishing arrangements of those pump-rooms are in accordance with the requirements for cargo pump-rooms. ; and c the following shall be added as paragraph (13): Additional requirements for ships constructed on or after 1st July 1998 13 a Where there is permanent access from a pipe tunnel to the main pump-room, a watertight door shall be fitted complying with the requirements of regulation 17(2) and, in addition to bridge operation, the watertight door shall be capable of being manually closed from outside the main pump-room entrance. b The watertight door referred to in subparagraph (a) above shall be kept closed during normal operations of the ship except when access to the pipe tunnel is required. . 9 In regulation 27 the following paragraphs shall be added at the end: 6 Non-metallic expansion joints in piping systems, if located in a system which penetrates the ship’s side and both the penetration and the non-metallic expansion joint are located below the deepest load waterline, shall be replaced as necessary, and at an interval recommended by the manufacturer. 7 Operating and maintenance instructions and engineering drawings for ship machinery and equipment essential to the safe operation of the ship shall be written in a language understandable by those officers and crew members who are required to understand such information in the performance of their duties. Additional requirements for ships constructed on or after 1st July 1998 8 Location and arrangement of vent pipes for fuel oil service, settling and lubrication oil tanks shall be such that in the event of a broken vent pipe this shall not directly lead to the risk of ingress of seawater splashes or rainwater. Two fuel oil service tanks for each type of fuel used on board necessary for propulsion and vital systems or equivalent arrangements shall be provided for each new ship, with a capacity of at least 8 hours at maximum continuous rating of the propulsion plant and normal operating load at sea of the generator plant. . 10 In regulation 28: a the existing paragraph (1) shall be renumbered (1)(a); and b the following shall be added to paragraph (1): b In ships constructed on or after 1st July 1998, main and auxiliary machinery essential for the propulsion, control and safety of the ship shall be provided with effective means for its operation and control. All control systems essential for the propulsion, control and safety of the ship shall be independent or designed such that failure of one system does not degrade the performance of another system. . 11 In regulation 47 the following paragraphs shall be added at the end: Additional requirements for ships constructed on or after 1st July 1998 8 a Where the main source of electrical power is necessary for propulsion and steering of the ship, the system shall be so arranged that the electrical supply to equipment necessary for propulsion and steering and to ensure safety of the ship will be maintained or immediately restored in the case of loss of any one of the generators in service. b Where the main source of electrical power is necessary for propulsion of the ship, the main busbar shall be subdivided into at least two parts which shall normally be connected by circuit breakers or other approved means. So far as is practicable, the connection of generating sets and other duplicated equipment shall be equally divided between the parts. 9 A ship complying with paragraph (8) need not comply with paragraph (7). . 12 In regulation 49 the following paragraph shall be added at the end: Additional requirements for ships constructed on or after 1st July 1998 3 Where electrical power is necessary to restore propulsion, the capacity shall be sufficient to restore propulsion to the ship in conjunction with other machinery, as appropriate, from a dead ship condition within 30 minutes after blackout. . 13 After regulation 54, the following regulations shall be inserted: Safe access to tanker bows 54A Every tanker constructed on or after 1st July 1998 shall be provided with the means to enable the crew to gain safe access to the bows even in severe weather conditions. For tankers constructed before 1st July 1998, such means of access shall be provided at the first scheduled dry-docking after 1st July 1998, but not later than 1st July 2001. The means of access shall be in accordance with Schedule 15 of Merchant Shipping Notice MSN 1671(M) (Amended) . Corrosion prevention of seawater ballast tanks Requirements for oil tankers and bulk carriers constructed on or after 1st July 1998 54B All dedicated seawater ballast tanks shall have an efficient corrosion prevention system, such as hard protective coatings or equivalent. The scheme for the selection, application and maintenance of the system shall be Schedule 16 of Merchant Shipping Notice MSN 1671 (M) (Amended). Combustible gas indicators 54C All tankers shall be equipped with at least one portable instrument for measuring flammable vapour concentrations, together with a sufficient set of spares.
