126. No provision.

127. Application
Regulations 128 to 142 inclusive apply to tankers of Classes VII(T), VIII(T), VIII(A)(T) and IX(A)(T) of 500 tons and over carrying crude oil and petroleum products having a closed flash-point not exceeding 60oC, and the Reid vapour pressure of which is below that of atmospheric pressure, or other liquids having a similar or additional fire hazard; and to gas carriers. 

128. Structure
(1) The hull, superstructures, structural bulkheads, decks and deckhouses shall be constructed of steel or other equivalent material, except that the crowns and casings of machinery spaces of Category A and the exterior boundaries of superstructures and deckhouses which are required to be insulated to “A-60” standard in compliance with regulation 129, shall be constructed only of steel.
(2) Where any part of the structure is of aluminium alloy, the following requirements shall apply—
(a) the insulation of aluminium alloy components of “A” Class divisions or “B” Class divisions, and supports of such divisions, shall be such that the temperature of the structural core does not rise more than 200°C above the ambient temperature at any time during a standard fire test of 60 minutes duration in the case of an “A” Class division and 30 minutes duration in the case of a “B” Class division; and
(b) the insulation of aluminium alloy components of columns, stanchions and other structural members required to support lifeboat and liferaft stowage, launching and embarkation areas, shall be such that the temperature rise limitation specified in paragraph (a) shall apply for 60 minutes duration.

128A. Helicopter decks
(1) Subregulations (2), (3) and (4) apply to a post 1992 ship (other than a post-1998 ship) having a helicopter deck. (L.N. 254 of 2018)
(1A) Subregulation (5) applies to a post-1998 ship. (L.N. 254 of 2018)
(2) Subject to subregulation (4), the helicopter deck shall be of steel equivalent fire-resistant construction.
(3) If the space below the helicopter deck is of a high fire risk, the insulation standard shall be to the satisfaction of the Director.
(4) If the Director so permits, the helicopter deck may be constructed of aluminium or other low melting metal construction that is not made equivalent to steel, except that—
(a) if the platform is cantilevered over the side of the ship, then, after the occurrence of a fire on the ship or on the platform, the platform shall undergo a structural analysis to determine its suitability for further use;
(b) if the platform is located above the ship’s deckhouse or similar structure—
(i) the deckhouse top and bulkheads under the platform shall have no openings;
(ii) all windows under the platform shall be provided with steel shutters;
(iii) after a fire on or in close proximity to the platform, the platform shall undergo a structural analysis to determine its suitability for further use.
(5) Provisions of helicopter facilities on a ship must be in accordance with the Standards for On-board Helicopter Facilities adopted by the International Maritime Organization by Resolution A.855(20). (L.N. 254 of 2018)
(L.N. 410 of 1995)

130. Boundary bulkheads and decks of machinery spaces of Category A and cargo pump rooms
(1) Windows and sidescuttles shall not be fitted in internal or external boundary bulkheads or decks of machinery spaces of Category A and cargo pump rooms, or in skylights to such spaces, except that such windows and sidescuttles may be fitted in a bulkhead between a machinery space of Category A and a machinery control room located within the boundaries of such a space.
(2) Skylights to machinery spaces of Category A and cargo pump rooms shall be capable of being closed and opened from outside the spaces which they serve.

131. Bulkheads within accommodation spaces, service spaces and control stations
(1) All bulkheads which are not required to be either “A” Class divisions or “B” Class divisions shall be “C” Class divisions.
(2) All bulkheads required to be “B” Class divisions shall extend from deck to deck and to the shell plating or other boundaries, except that where continuous “B” Class ceilings and/or linings are fitted on both sides of the bulkheads the bulkheads may terminate at such ceilings and/or linings.
(3) All materials used in the construction of “B” Class divisions and “C” Class divisions and doors in “B” Class bulkheads and “C” Class bulkheads shall be non-combustible.

133. Protection of stairways and lifts in accommodation and service spaces
(1) Every stairway within accommodation spaces, service spaces and control stations shall be constructed of steel except where the Director may approve the use of other equivalent material. Every such stairway and lift shall lie respectively within an enclosure or trunk constructed of “A” Class divisions of “A-0” standard except that an isolated stairway serving only two decks shall only be required to be enclosed at one level by either “A” Class divisions of “A-0” standard or “B” Class divisions of “B-0” standard provided that the fire integrity of any bulkhead which separates a stairway from either a machinery space of Category A or a cargo pump room shall be determined by reference to table 9 of regulation 132. (E.R. 1 of 2022)
(2) Every opening in a stairway enclosure and lift trunk shall be provided with a means of closure which shall be permanently attached thereto and which shall comply with the requirements of regulation 134 or 135 whichever is applicable.

134. Openings in “A” Class divisions
(1) Where an “A” Class division is pierced for the passage of electric cables, pipes, trunks, girders or beams or for other purposes, the arrangements shall be such that the effectiveness of the division in resisting fire is not thereby impaired.
(2) The construction of all doors and frames in “A” Class bulkheads, with the means of securing the doors when closed, shall provide resistance to fire as well as to the passage of smoke and flame, as far as is reasonably practicable, equivalent to that of the bulkheads in which the doors are situated.
(3) Every door in an “A” Class bulkhead shall be so constructed that it can be opened and closed by one person from either side of the division.
(4) Every door in an “A” Class bulkhead which forms part of a stairway enclosure or lift trunk serving accommodation spaces, service spaces or control stations and every door in a casing of a machinery space of Category A shall be self-closing.
(5) Hold-back arrangements may be fitted to doors to which subregulation (4) refers provided that such arrangements—
(a) have remote release fittings of a type which in the event of disruption of the control system will automatically close the doors; and
(b) will permit each door to be closed manually.
(6) Doors fitted in boundary bulkheads of machinery spaces of Category A shall be reasonably gastight and self-closing.
(7) Watertight doors need not be insulated.
(8) Where ventilation ducts pass through “A” Class divisions the requirements of regulation 136 shall apply.
