See Figures B and C.
1.4.1 Determine if spoil will spill over the hopper coaming, i.e.
if the volume of the cargo in upright position is greater than V_{max} for
the particular angle of heel.
If not, the total displacement is not
changed from that in the upright position, then proceed as indicated in 1.4.3.
If spoil will spill over the hopper coaming, proceed as indicated in 1.4.2.
1.4.2 Determine for the given V_{h} (=V_{max}) the
value of y_{h} from the graph, Figure B.
Determine for the displacement _{} the value of
y_{s} from the graph, Figure C.
If y_{h}> y_{s}, proceed as indicated in 1.4.3;
if y_{h} < y_{s}, proceed as indicated in 1.4.4.
1.4.3 Calculation of the righting levers when water will not
penetrate y_{h}> y_{s}.
Determine for the given V_{h} the value of _{}from the graph, Figure B.
Determine for the given the
value of _{} from the
graph, Figure C.
Then the righting lever is:
1.4.4 If y_{h} < y_{s}, water will penetrate
into the hopper, then:
Determine the new value of y_{s} based on .
Repeat this calculation,
until the difference between the assumed y_{s} and the calculated
y_{s} is neglectible small, then equilibrium is reached.
Now proceed as indicated in 1.4.5.
1.4.5 Calculation of righting levers when y_{h} <
y_{s}
With the values of ,
V_{h} and V_{w} the following data can be calculated;
_{} = f (), Figure C
= f (V_{h}),
Figure B
=
f (V_{w}), Figure B (identical to _{} = f (V_{h}), where V_{w} =
V_{h})
Then:
Usually y_{h} < y_{s} occurs only at large angles of heel.
