KG Limit - Intact (from GM-required)
Maximum allowable KG (fluid) for an intact condition given KM at the draft and the required minimum GM.
Maximum KG (solid)
10.840m
Formula, assumptions, and limits
$$KG_{max} = KM - GM_{req} - \sum \frac{F_{SM}}{\Delta}$$
Loading computer tabulates KG-limit vs mean draft. Update FSM every condition for partially filled tanks, including consumables.
