🔍 Key Concepts

• Transverse Center of Gravity (TCG) and how shifting or discharging weight affects it • Using the lateral moments from the load form to find the total moment and then dividing by displacement • Effect on TCG when weights are removed from tanks located off the centerline

💭 Think About

• From the Sample Load Form #3, identify the original total transverse moment and total displacement. How is TCG calculated from these values? • When you discharge the bulk in Bulk Tanks 1 and 2, how do the total transverse moment and total displacement change? Do they both change, or only one of them? • Are Bulk Tanks 1 and 2 located to port, starboard, or on the centerline? Based on that, will removing their contents move TCG toward port, toward starboard, or toward the centerline?

✅ Before You Answer

• Confirm the sign convention for port and starboard moments/TCGs used on the load form before doing any math. • Recalculate the new total transverse moment after removing the weight and its associated lateral moment from Bulk Tanks 1 and 2. • Use the correct formula: TCG = (Total Transverse Moment) / (Displacement) and keep track of whether displacement decreases when cargo is discharged.
