Bulk grain loading plans- specially suitable ships
PART IV-GRAIN LOADING PLANS
27. (1) A reference in this Part to a specially suitable ship is a reference
to a ship constructed with two or more vertical, or sloping, grain-tight
longitudinal divisions that are so placed that they limit the effect of a
transverse shift of grain carried in the ship.
(2) The Minister shall approve a plan for the loading of bulk grain in a
specially suitable ship that is registered in Australia if he is satisfied
that-
(a) the plan provides that, when grain is loaded in the ship, as many holds
and compartments as possible will be full and trimmed full; and
(b) the plan provides for the grain to be so stowed that, while it is in
the ship, the ship will not list to an angle greater than five degrees on the
assumptions-
(i) that a sinking of grain amounting to two per cent of the volume of
the hold or compartment in which the grain is carried will take place;
(ii) that a shift of the grain surface, in the case of a hold or
compartment while filled with bulk grain, to an angle of twelve degrees from
the horizontal under all the boundaries of the hold or compartment that are at
an angle of less than thirty degrees to the horizontal will take place;
(iii) that a shift of the free grain surface, in the case of a hold or
compartment partly filled with bulk grain, to an angle of twelve degrees from
the horizontal or such larger angle as the Minister, in a particular case,
approves will take place;
(iv) that a shift of the free grain surface, in the case of a hold or
compartment partly filled with bulk grain and overstowed in accordance with
the provisions of sub-regulation (4) of regulation 14 of these Regulations, to
an angle of eight degrees from the horizontal will take place; and
(v) shifting boards, if fitted, will limit the transverse shift of the
surface of the grain.
NAVIGATION (GRAIN) REGULATIONS - SECT. 28.
Bulk grain loading plans-other ships
28. The Minister may approve a plan for the loading of bulk grain in a ship
registered in Australia, not being a specially suitable ship, if he is
satisfied that, when grain is loaded in the ship in accordance with the plan,
the whole of the cargo in the ship is so stowed that, while the cargo is in
the ship, the ship will be as stable as it would have been if the requirement
of Part III of these Regulations had been complied with in relation to the
ship.
NAVIGATION (GRAIN) REGULATIONS - SECT. 29.
Requirements in relation to plans
29. (1) An application for an approval of a plan for the loading of bulk

plan.
(2) The plan-
(a) shall contain details of the manner in which the grain is to be stowed
in the ship;

taken to prevent the grain from shifting; and
(c) shall have endorsed on or attached to it a calculation of the stability
of the ship when so loaded together with such information as is necessary to
calculate the stability of the ship when so loaded and, in the case of a
specially suitable ship, such information as is necessary to show that the
ship when so loaded will not, at any stage of the voyage, list to an angle
greater than five degrees.
