What is the change in transverse moments for the DEEP DRILLER if 103.48 long tons of ballast is discharged from a full ballast tank 1P?

🔍 Key Concepts

• Transverse moment = weight × transverse distance from the centerline • Discharging ballast means the weight is removed from its original location • Sign convention: decide what is a positive vs negative transverse moment change before you compute

💭 Think About

• From the hydrostatic/loading data for DEEP DRILLER, what is the transverse distance (T-arm) of tank 1P from the centerline? • How do you compute the transverse moment created by a given weight located at a known transverse arm? • When that weight is discharged, how does the ship’s total transverse moment change in magnitude and in sign?

✅ Before You Answer

• Confirm the T-arm of 1P in feet from the exam loading manual or table • Multiply 103.48 long tons × T-arm (feet) to get foot-tons, then compare with the options • Check whether removing a port-side ballast weight causes an increase or decrease in total transverse moment based on your sign convention
