🔍 Key Concepts

• Longitudinal moment = weight × longitudinal distance from the reference (usually FP or AP) • Effect on moments when weight is discharged (removed) versus when it is loaded • Using data from the loading manual/particular tank data for DEEP DRILLER: tank capacity, LCG of tank, and proportion of tank used

💭 Think About

• How do you compute the longitudinal moment of a weight in a specific tank once you know the long tons and the longitudinal center of gravity (LCG) of that tank? • When ballast is discharged, does the ship’s total longitudinal moment increase or decrease, and by exactly how much compared to the original weight’s moment? • Is the moment change equal to the full tank’s moment, or only the moment of the quantity actually discharged (103.48 long tons)?

✅ Before You Answer

• Confirm the LCG position for tank 1P from the hydrostatic or tank data tables used for DEEP DRILLER problems. • Carefully check that you are using long tons and feet so the moment is in foot-tons, not mixing units. • Verify that you apply the correct sign (increase or decrease) to the change in longitudinal moment when ballast is discharged, then match the magnitude and direction to the closest choice.
