What is the increase in transverse moments for the Coastal Driller if 2.0 feet of drill water is transferred from a full drill water tank 23 to an empty drill water tank 6?

🔍 Key Concepts

• Transverse moment = weight × transverse distance (moment arm) • Effect of transferring liquid between tanks on total moment (one tank losing weight, one gaining weight) • Using the Coastal Driller stability data: tank capacities, centers, and specific gravity of drill water

💭 Think About

• How does removing 2.0 feet of liquid from a full tank change that tank’s transverse moment? Think about how the weight in that tank changes. • How does adding 2.0 feet of liquid to an empty tank change that tank’s transverse moment? Consider its transverse location relative to the centerline. • When you combine the change in moment from the source tank and the change from the receiving tank, how do you find the net increase in transverse moments?

✅ Before You Answer

• Confirm you are using the correct tank data for Tank 23 and Tank 6 from the Coastal Driller booklet (transverse distances and capacities per foot of liquid). • Be sure to convert any intermediate values so that weight is in kips and moment is in foot-kips. • Check that you treated one tank’s change as a decrease in moment (losing weight) and the other as an increase in moment (gaining weight) before finding the net change.
