Grain cargo calculations for USA, Canada and Australia - samples?

[Decepticon]

Dear seaman's,

I have an exam with grain cargo calculations for a vessel and I need to calculate RDS residual dynamic stability on 3 different ways by using USA, Canada and Australian method, and I can not find examples of solved tasks, just forms how to do it, but online forms are not very clear because some countries use LCF for distance from AP, and some from Midships. And also some countries use negative trim to be ship with deeper draught on stern, and negative trim deeper draught on bow.

This is the data given in the exam:
Ship Spar scorpio, SG of cargo = 0,8155 t/m3 (it could be SF or SG).
KG = (keel to c. o. gravity) 10,4 m
XG = (from AP to c. o. gravity) 94,47 m
FSC = 0,03 m (wich makes KG corrected = KG + FSC = 10,4 + 0,03 = 10,43m)

total Displacement = 64755 t
Data from HT for this displacement

Mean draft 12.565				m
TPC 57.300				t/cm
MCT 79734.3				tm
KM 13.680				m
LCB 96.544				m
LCF 88.914				m
LBP 183.05				m

angle							10°			20°			30°			40°			50°			60°
KN							2.407			4.805			6.800			8.601			9.886			10.607

CARGO

						VOLUME FULL						VOLUME PARTIAL										HEEL MOMENTS
AREA						m3						m3						MOMENTS				m4
HOLD 1.												12313.52						1742.15				1420.723
HOLD 2.						13347												688				561.064
HOLD. 3.												10678.96						18855.87				15376.962
HOLD 4.						13346.9												688				561.064
HOLD. 5.												13138.79						2015.46				1643.608

So, how do I calculate RDS by using 3 different methods with given data for vessel?
One is FAB area under GZ curve, above heeling lever moments curve, one is using factor C correction, and I am lost.

Thank you.
