the area.
       (5)The floor load is determined according to Formula 2:
Formula 2
F =
where:
F is the floor load, in newtons per square metre
d is the draught of the vessel corresponding to the anticipated lightest loaded water-line, in metres.
L is the length between the perpendiculars of the vessel, in metres.
y is the longitudinal distance from the midpoint of the pen to amidships, in metres.

Note   The approved stability booklet for the vessel contains the information for the load calculation.
       (6)Subsections (1) to (4) apply to the floor support of a sheep, pig or goat pen whether or not it also forms the top boundary of a lower tier pen.
       (7)For a sheep, pig or goat pen structure above the uppermost continuous deck, instead of compliance with subsections (1) to (5), AMSA may approve calculations that show that the rails and stanchions of the pens, the pen floors and the floor supports can withstand appropriate design forces, according to the criteria specified by the vessel's classification society for the design of the vessel structure.
       (8)The stresses for materials used in the construction of boundaries and floors of a pen must not exceed the figures in Table 5 when the materials are under the loads determined in accordance with subsections (1) and (5).

Material   Maximum permissible          Maximum permissible
           tensile stress               shear stress
Steel      0.75 × minimum yield stress  50% of maximum permissible tensile stress
Aluminium  0.75 × 0.2% proof stress     50% of maximum permissible tensile stress

60 Sheep, pigs and goats — arrangements of pens, walkways and passageways
       (1)There must be a passageway on at least 1 side of each pen.
Note   A passageway on the longest pen boundary provides better access for animals to feed.
       (2)If a lower tiered pen has a water or food receptacle beside a passageway, the upper tiered pen above it must have fitted to the side adjoining the passageway, to prevent the fouling of food and water of livestock in lower tiers, a vertical plate or board that:
(a) is at least 225 mm high; and
(b) abuts the floor of the pen.
       (3)If pens are constructed in more than 1 tier on a deck, walkways must be provided so that no pen floor is more than 1.5m above the deck or a walkway.

61 Goats — additional requirements
       (1)The following additional requirements apply to pens used for the carriage of goats:
(a) there must be pen rails:
 (i) to a height of at least 1.5 m above the pen floor; or
 (ii) to a height where the clear height above
