10    GM                                              GM      Vessel's information

3.3 Calculation
      (1) Livestock:
 Heeling lever at
      (2) Fodder:
 Heeling lever at
      (3) Wind:
 Heeling lever at
      (4) Angle of heel due to wind:
 Angle of heel =  = Q

3.4 Comparison with stability criteria
      (1) Check that area under righting lever curve is at least:
(a) 3.15 metre-degrees up to 30° angle of heel; and
(b) 5.16 metre-degrees up to 40° angle of heel, or angle of flooding if this angle is less than 40°.
      (2) Check that area under righting lever curve between the angles of heel of 30° and 40°, or, if this angle is less than 40°, between 30° and angle of flooding, is at least 1.72 metre-degrees.
      (3) Check that righting lever GZ is at least 0.20 metres at an angle of heel of at least 30°.
      (4) Check that maximum righting lever occurs at an angle of heel of at least 25°.
      (5) Check that initial metacentric height GM is at least 0.15 m.
      (6) Check that angle of heel due to wind effect is not more than 10°.
      (7) Check that area A is at least [1.03 metre-degrees + 0.2 area (A+B)].

               Schedule 2 Provision of livestock services
(subsection 35(2))
Note   Adherence to the standards set out in this Schedule will satisfy subsection 35(1). The following standards aim to ensure that livestock services are maintained even in the event of system failure. These standards will be used to measure any alternative arrangement proposed under subsection 35(3).

Part 1 Sources of electrical power for vessels

1.1 Main source
       The vessel's main source of power, as mentioned in Regulation 41 of Chapter II-1 of SOLAS must, in addition to being able to supply the services mentioned in Regulation 40.1.1 under the conditions mentioned in Regulation 41, be able to supply power to the livestock services under the same conditions.

1.2 Secondary source
       (1)A vessel must have at least 1 secondary source of power.
       (2)The secondary source of power must:
(a) be located in an area that is not contiguous with a space that contains any part of the main source of power; and
(b) be independent of any services provided from or through a space that contains the main source of power; and
(c) have a prime mover that is capable of being started easily by an arrangement powered by an independent source of energy that can fully recharge the starting arrangement within 30 minutes; and
(d) be able to supply power to livestock services for at least 3 days if the main source of power fails for any reason; and
(e) be maintained in a condition acceptable to the vessel's classification society; and
(f) in conjunction with ancillary systems
