🔍 Key Concepts

• TPI (Tons Per Inch Immersion) for this vessel and how to use it • Relationship between weight removed and change in draft • Unit consistency: long tons, inches, and feet

💭 Think About

• If you remove weight, will the draft increase or decrease? Visualize how the vessel sits in the water. • About how many inches of draft change would you expect per long ton on a large offshore unit like DEEP DRILLER? Does 68.94 LT give a big or small change? • Once you estimate the total change in inches, how do you convert that to feet and apply it to the original 60.0-foot draft?

✅ Before You Answer

• Make sure you are using the correct TPI value given elsewhere on the exam/reference sheet for DEEP DRILLER. • Ensure you convert inches of draft change to feet before comparing with the answer choices. • Confirm that your final draft direction (more or less draft) matches the fact that ballast was discharged (removed), not added.
