SAFETY OF LIFE AT SEA C163 



Regulation 12 



Stowage of specially suitable ships 



(a) Notwithstanding anything contained in Regulations 4 to 11 of this 

 Chapter, bulk grain may be carried without regard to the requirements 

 specified therein in ships which are constructed with two or more vertical or 

 sloping grain-tight longitudinal divisions suitably disposed to limit the effect 

 of any transverse shift of grain under the following conditions : — 



(i) as many holds and compartments as possible shall be full and trimmed 

 full; 



(ii) for any specified arrangement of stowage the ship will not list to an 

 angle greater than 5 degrees at any stage of the voyage where : — 



(1) in holds or compartments which have been trimmed full the 



grain surface settles 2 per cent, by volume from the original 

 surface and shifts to an angle of 12 degrees with that surface 

 under all boundaries of these holds and compartments which 

 have an inclination of less than 30 degrees to the horizontal; 

 and 



(2) in partly filled holds or compartments free grain surfaces settle 



and shift as in sub-paragraph (ii) (1) of this paragraph or 

 to such larger angle as may be deemed necessary by the 

 Administration, or by a Contracting Government on behalf 

 of the Administration, and grain surfaces if overstowed in 

 accordance with Regulation 5 of this Chapter shift to an 

 angle of 8 degrees with the original levelled surfaces. For 

 the purposes of sub-paragraph (ii) of this paragraph shifting 

 boards if fitted will be considered to limit the transverse 

 shift of the surface of the grain; 



(iii) the master is provided with a grain loading plan covering the stowage 

 arrangements to be adopted and a stability booklet, both approved 

 by the Administration, or by a Contracting Government on behalf 

 of the Administration, showing the stability conditions upon which 

 the calculations given in sub-paragraph (ii) of this paragraph are 

 based. 



(b) The Administration, or a Contracting Government on behalf of the 

 Administration, shall prescribe the precautions to be taken against shifting in 

 all other conditions of loading of ships designed in accordance with 

 paragraph (a) of this Regulation which meet the requirements of sub- 

 paragraphs (ii) and (iii) of that paragraph. 



(c) The Administration, or a Contracting Government on behalf of the 

 Administration, shall prescribe the precautions to be taken against shifting 

 in a ship of any other design which meets the requirements of sub- 

 paragraphs (ii) and (iii) of paragraph (a) of this Regulation.
