12    Minimum width of adjacent passageway clear of receptacles and any other obstructions                                                                                                 550 mm

       (2)For item 5, the clear floor area is the area of the pen excluding fixed receptacles, other objects or structures in the pen, but including a bar fitted in accordance with subclause 5.5(4) of Schedule 2.
       (3)For an open structure above the weather deck, if pen rails or gates form the outer perimeter containment:
(a) the space between the bottom edge of the lowest rail and the top of the deck boundary angle must be no more than 100 mm; and
(b) the space between the rails above the bottom rail must be no more than 200 mm; and
(c) the railing must continue to a height that is no more than 200 mm below the overhead structure of the vessel.
       (4)However, for a vessel that was constructed or converted for the carriage of livestock before 1 July 2018 the railing is not required to comply with paragraph (3)(c) until 1 July 2023.
       (5)The decks for pens, passageways and ramps between decks must have a surface that provides a non-slip foothold for sheep.

59 Sheep, pigs and goats — strength of pen structures
       (1)Rails and stanchions that form a fore and aft boundary of a sheep, pig or goat pen must be able to withstand a load per metre length, uniformly distributed up to the height of the top of the uppermost rail, using Formula 1:
Formula 1
F = 1668 B (0.574 + 0.0252 Z)
where:
F is the boundary load in newtons per metre length
B is the maximum breadth of the pen, in metres.
Z is the vertical distance from a point 0.5 m above the pen floor to the vessel's water-line corresponding to the anticipated lightest load, in metres

Note   The approved stability booklet for the vessel contains the information for the load calculation.
       (2)However, a rail the centre of which is more than 900 mm above the pen floor is not to be included in the load calculations.
       (3)Rails and stanchions that form a boundary, other than a fore and aft boundary, of a sheep, pig or goat pen must be of substantially the same method of construction and of substantially the same scantlings as required for the fore and aft boundaries.
       (4)Any two-thirds of the area of the floor of a sheep, pig or goat pen must be able to withstand 100% of the floor load uniformly distributed over 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,
