1 amending act · 2016-08-30, S.I. No. 455/2016 - Carriage of Livestock by Sea (Amendment) Regulations 2016
The effect of wind should be taken into account in the following manner:
- (a) The heeling lever due to the effect of wind at 0° is to be given by:
- (PAH) divided by (Displacement)
where:
- (i) P (wind pressure) is 0.05 tonnes/m2,
- (ii) A is the lateral area of the vessel above the waterline in square metres, and
- (iii) H is the vertical distance between the control of the lateral area of the vessel above the waterline and the centroid of the vessel’s underwater lateral area.
Note: For both subparagraphs (ii) and (iii) the lateral area and height of baled hay carried on deck must be taken into account.
Note: For many vessels the vertical position of the centroid of the underwater lateral area may be taken at half the draft to the underside of the keel at amidships.
- (b) The heeling lever due to the effect of wind at 40° is to be given by:
8 (heeling lever due to the effect of wind at 0°).
- (c) The heeling lever curve is to be taken as a straight line joining the heeling lever at 0° and the heeling lever at 40°.
ILLUSTRATION OF STABILITY REQUIREMENTS
where:
- (i) OW is the heeling lever at 0° due to wind,
- (ii) WW1 is the heeling lever curve due to wind,
- (iii) WL is the heeling lever at 0° due to the shift of livestock,
- (iv) LL1 is the heeling lever curve due to the combined effects of the wind and the shift of livestock,
- (v) LF is the heeling lever at 0° due to the effect of shift of feed,
- (vi) FF1 is the heeling lever curve due to the combined effects of wind and the shift of livestock and feed, and
(vii)é is the angle of heel due to wind.
Note: If feed is not pellet feed carried in bulk, the heeling lever due to shift of feed will be zero.
B. Information to be provided on vessel
The following stability information should be provided on the vessel:
- (a) Livestock shift constant:
The livestock shift constant is to be determined for all conditions of pen utilization that may arise in practice unless the maximum value is used for all calculations.
- (b) Heeling moment for feed:
The heeling moment for each compartment is to be determined separately unless the greatest heeling moment for all compartments added together is provided: that is, the total heeling moment for the worst condition of stability.
- (c) Wind effect:
The values of A and H will vary with the draft of the vessel. Values therefore are to be provided for the range of drafts that may occur in practice or alternatively the wind effect:
- (PAH) divided by (Displacement) may be given in tabular or graphical form.
C. Method of calculations
The following method of calculation may be used to demonstrate compliance.
(Other methods may be used).
- (a) Information required:
| Livestock shift constant | = C (from vessel’s information) |
| Average Mass of livestock per animal | = m (from shipper’s declaration) |
| Floor area per animal | = f (from table in Regulation 25) |
| Feed heeling moment | = F (from vessel’s information) |
| Stowage factor of feed | = S (from master) |
| Lateral area of vessel above waterline | = A (from vessel’s information) |
| Vertical separation of centroids | = H (from vessel’s information) |
| Wind pressure | = P (0.05 tonnes/square metre) |
| Displacement | = D (from vessel’s information) |
| GM | = GM (from vessel’s information) |
| Moulded breadth | = B (from vessel’s information) |
- (b) Calculation:
| (i) Livestock: Heeling lever at 0° = | [image omitted] |
| (ii) Feed: Heeling lever at 0° = | [image omitted] |
| (iii) Wind: Heeling lever at 0° = | [image omitted] |
| --- | --- |
| (iv) Angle of heel due to wind: Angle of heel = | [image omitted] |
| (v) Roll period: | [image omitted] |
In calculating the stability of the vessel, the use of fuel oil, fresh water and feed, the movement of ballast and the build up of waste material shall be taken into account.

EXPLANATORY NOTE.
(This note is not part of the Instrument and does not purport to be a legal interpretation)
These Regulations update and consolidate regulations for the carriage of livestock by sea from the State.
They provide for the inspection and approval of livestock vessels which comply with specified criteria, the loading and care of livestock on vessels, conditions in relation to weather and the submission of voyage reports.
