🔍 Key Concepts

• Longitudinal center of buoyancy (LCB) moves toward the center of the underwater volume, not toward weight directly • Effect of removing a liquid load located forward or aft on the vessel’s trim and LCB • Using a moment summary (distance × volume/weight) along the length of the unit to find a new LCB position

💭 Think About

• On the Sample Load Form #4, identify where the liquid mud tanks are located longitudinally: are they forward or aft of the reference (0.00 ft)? • When you dump the liquid mud, does the underwater volume (and therefore buoyancy) need to shift forward or aft to keep the vessel in equilibrium? • How does removing a weight at a known longitudinal position affect the total longitudinal moment and thus the calculated LCB (total moment ÷ total displacement)?

✅ Before You Answer

• Verify the longitudinal arm (distance in feet) of the liquid mud with respect to the chosen reference (usually amidships or FP/AP, as shown on the form). • Recalculate the total displacement and total longitudinal moment after the liquid mud is removed, and then compute: LCB = total longitudinal moment ÷ total displacement. • Check the direction of shift: confirm whether the new LCB should be slightly forward or slightly aft of the original value before selecting the closest numerical choice.
