3 Assumed volumetric heeling moment of a filled compartment, untrimmed

  3.1 All the provision for filled compartments, trimmed, set forth in B 2 shall also apply to filled compartments, untrimmed, except as noted below.

  3.2 In filled compartments, untrimmed, which are exempted from trimming outside the periphery of the hatchway under the provisions of A 10.3.1:

  • .1 the resulting grain surface after shifting shall be assumed to be at an angle of 25° to the horizontal. However, if in any section of the compartment, forward, aft, or abreast of the hatchway the mean transverse area of the void in that section is equal to or less than the area which would obtain by application of B 1.1, then the angle of grain surface after shifting in that section shall be assumed to be 15° to the horizontal; and

  • .2 the void area at any transverse section of the compartment shall be assumed to be the same both before and after the grain shift, i.e. it shall be assumed that additional feeding does not occur at the time of the grain shift.

  3.3 In filled compartments, untrimmed, which are exempted from trimming in the ends, forward and aft of the hatchway, under the provisions of A 10.3.2:

  • .1 the resulting grain surface abreast of the hatchway after shifting shall be assumed to be at an angle of 15° to the horizontal; and

  • .2 the resulting grain surface in the ends, forward and aft of the hatchway after shifting shall be assumed to be at an angle of 25° to the horizontal.
