🔍 Key Concepts

• Transverse moment is the tank’s load (weight of liquid) multiplied by its transverse distance from the vessel’s centerline • You must use the tank capacity curves / sounding tables for the specific vessel COASTAL DRILLER to get volume and LCG/TCG at 10.5 ft in preload tank #2 • Convert the volume of sea water (from tables) to weight in kips and then multiply by the correct transverse lever arm

💭 Think About

• From the loading manual/sounding tables, what is the volume of sea water and the transverse center of gravity (TCG) for preload tank #2 at 10.5 ft? • How do you convert that volume of sea water to weight, and how does that weight relate to the transverse moment you are being asked for? • After calculating the transverse moment, which answer choice is closest to your computed value, considering significant figures and unit consistency?

✅ Before You Answer

• Be sure the density used is for sea water, not fresh water • Confirm the units: moment should be in kips-feet (weight in kips × distance in feet) • Verify that you are using the correct tank diagram and table for preload tank #2 on COASTAL DRILLER, and that you are reading the TCG at 10.5 ft correctly (interpolate if needed)
