(5) Where the calculation is made by means of a shore-based loading and stability computer system, a print-out of the calculation shall be presented to the master before the ship proceeds on its voyage. It shall be the duty of the person responsible for that system to ensure that the calculations are substantially correct. (6) A full record of the calculation or a copy thereof, shall be retained on the ship for at least one calendar month after the calculation is made and shall be made available for inspection at any time during that period. (L.N. 138 of 1994) Cap 369AL reg 9G Permissible standard of stability to be recorded Before a ship of Class I, Class II or Class II(A) proceeds on a voyage the master shall cause the maximum permissible KG, or the minimum permissible GM, whichever is appropriate to the ship, to be determined and recorded in the official log book. (L.N. 138 of 1994) Cap 369AL reg 9H Condition of loading prior to departure to be satisfactory Before a ship of Class I, Class II or Class II(A) proceeds on a voyage the master shall ensure that the condition of loading of the ship as recorded in accordance with regulations 9E(2) and 9F(4) is within the permissible standard of stability determined in accordance with regulation 9G and satisfies all the relevant requirements prescribed in the stability information book. (L.N. 138 of 1994) Cap 369AL reg 9I Draught marks and automatic draught gauge system (1) Every ship of Class II shall be provided with a reliable automatic draught gauge system, complying with the requirements of Merchant Shipping Notice No. M1413. (2) (a) Every ship of Class I or Class II(A) engaged on services which afford only short periods in port or where insufficient lighting is available during periods of darkness, or which include the use of berths exposed to adverse weather, shall be provided with a reliable automatic draught gauge system as prescribed in subregulation (1). (b) Every other ship of Class I or Class II(A) shall be provided with such an automatic draught gauge system except where the draught marks are located where they can be easily read. (L.N. 138 of 1994) Cap 369AL reg 10 Intact stability (1) Every ship to which this Part applies shall, in all probable loading conditions, satisfy the following stability criteria after due correction for the effect of free surface of liquids in tanks- (a) the area under the curve of righting levers (GZ curve) shall not be less than- (i) 0.055 metre-radian up to an angle of 30o; (ii) 0.09 metre-radian up to an angle of either 40o or the angle at which the lower edges of any openings in the hull, superstructures or deckhouses, being openings which cannot be closed weathertight, are immersed if that angle be less; (iii) 0.03 metre-radian between the angles of heel 30o and 40o or such lesser angle as is referred to in sub-subparagraph (ii);(b) the righting lever (GZ) shall be at least 0.20 metre at an angle of heel equal to or greater than 30o; (c) the maximum righting lever (GZ) shall occur at an angle of heel not less than 30o; (d) the initial transverse metacentric height shall not be less than 0.15 metre.(2) Where it is not possible, due to the particular design or operating conditions of a particular ship, to comply with the above criteria, the Director may permit the application of such alternative criteria as he is satisfied gives a standard of stability at least as effective as that specified in subregulation (1). (Enacted 1991) Cap 369AL reg 11 Stability in damaged condition (1) (a) In addition to the requirements of regulation 10, every ship to which this Part applies shall be so constructed as to provide sufficient intact stability in all service conditions to enable the ship to withstand the final flooding of any one of the main compartments into which the ship is subdivided in accordance with the provisions of regulation 6. If 2 of the main compartments, being adjacent to each other, are separated by a bulkhead which is stepped under the conditions of paragraph 6(3)(a) of Schedule 1, the intact stability shall be adequate to withstand the final flooding of those 2 adjacent main compartments. (b) Where in any such ship the factor of subdivision required under paragraph 4 or paragraph 9 of Schedule 1 is .50 or less but more than .33, the intact stability shall be adequate to withstand the final flooding of any 2 adjacent main compartments. (c) Where in any such ship the factor of subdivision required under paragraph 4 of Schedule 1 is .33 or less, the intact stability shall be adequate to withstand the final flooding of any 3 adjacent main compartments.(2) For the purposes of this regulation the sufficiency of the intact stability of every such ship shall be determined in accordance with the provisions of Schedule 3. (3) (a) Every ship to which this Part applies shall be so constructed as to keep unsymmetrical flooding when the ship is in a damaged condition at the minimum consistent with efficient arrangements. If cross-flooding fittings are provided in any such ship the fittings shall, where practicable, be self-acting but in any case where controls to cross-flooding fittings are provided, they shall be capable of being operated from an accessible position above the bulkhead deck. Such fittings together with their controls as well as the maximum heel before equalization shall be such as will not endanger the safety of the ship. The cross-flooding fittings shall be capable of reducing the heel within 15 minutes, sufficiently to meet the requirements of paragraph 3(b) of Schedule 3. |
