Question 1 of 31048

What are the maximum vertical moments including free surface moments permitted on the DEEP DRILLER at a draft of 60 feet if the winds are greater than 70 knots?

🔍 Key Concepts

• Stability booklet / operating manual tables for DEEP DRILLER • Effect of free surface moments on vertical moments and stability limits • How wind speed conditions (greater than or less than 70 knots) change allowable limits

💭 Think About

• Identify which table or graph in the DEEP DRILLER stability data specifically covers maximum vertical moments vs. draft under different wind conditions • At a draft of exactly 60 feet, determine whether you should read directly from the 60-foot line or interpolate, and make sure you’re in the correct wind column (> 70 knots) • Compare the value you obtain from the manual with the answer choices, paying attention to units (foot-tons) and whether free surface is already included

✅ Before You Answer

• Confirm you are using the correct wind condition column (winds greater than 70 knots) in the stability booklet • Verify that the vertical moment value you choose includes free surface moments and is not the ‘without free surface’ column or line • Double-check that the draft is 60 feet, not an upper or lower limiting draft where interpolation would be required
