Section X. LIQUID LOADING DIAGRAM
5-35. PURPOSE. The purpose of the Liquid Loading Diagram (FIGURE FO-1) is three-fold: a. To show the distribution
and amount of liquids normally carried on board.
b. To prescribe the loading which will insure proper conditions of stability and trim.
c. To show the effect on trim and heel of filling each tank with its normal capacity of liquid.
In the upper left corner appears the normal capacity of the tank in tons. For diesel oil tanks, this would be the
weight of oil at 95% full. For ballast tanks, it is the weight of salt water at 100% full, and for fresh water tanks, it is the
weight of fresh water at 100% full.
In the upper right corner is shown the change of list that will result from filling each tank to the above capacities. The
figures in the lower right and left corners show the changes in draft forward and aft, respectively, to be expected from
filling the tank.
Two sets of values for trimming effects are provided, one for the full-load departure condition and the other for full-
load arrival condition.
Section XI. CURVE OF RIGHTING LEVERS
5-36. INTRODUCTION. FIGURE 5-5 shows the variation of righting arms (GZ), with angle of heel, for an assumed
height of center of gravity (KG) of 19.6 feet above bottom of keel amidships. For any condition of loading in which
displacement and KG are known, a curve of intact statical stability can be developed. This curve is for the beaching
condition. FIGURES 5-6, 5-7, and 5-8 are for the full-load departure, full-load arrival, and light ship condition
respectively.
As an example, the curve of intact statical stability for the beaching condition was developed.
