 TM 55-1905-223-SDC
Section IX. STANDARD CONDITIONS OF LOADING
5-35. CONDITIONS. In the Intact/Damage Stability Report, nine representative conditions of loading have
been calculated to represent the full range of the operating drafts. Usually, these ships will operate
somewhere between the full-load departure (with deck containers) and the beaching condition drafts.
The baseline for all calculations, drafts, and functions of form is the bottom of keel amidships. The
vertical moments of all load items have been calculated above the bottom of keel at the AP and the result
corrected to the bottom of keel amidships.
The reference line for longitudinal calculations is amidships, which is Frame 23.
a. Light ship condition. This condition is the ship complete, ready for service in every respect,
including liquids in machinery at operating levels, without items of consumable or variable load.
Weight
575 Tons
Vertical Center of Gravity
10.73 Ft. above Keel @ AP
Longitudinal Center of Gravity
12.16 Ft. Aft of Midships
Included in this condition are:
Fixed Ballast
None
Armament
Two 50-Cal. Machine Guns
Boats
13-ft. Rigid, Inflatable
Workboat
Two Life Rafts
b. Full-load departure condition. This is a typical condition which depicts the loading and the
stability characteristics of the ship when fully loaded with cargo at the beginning of an extended voyage.
Ballast tanks are empty.
