The COASTAL DRILLER is in transit at a draft of 10.0 feet. It loads 216.43 kips of weight aboard. What is the new draft?

🔍 Key Concepts

• TPI (Tons per Inch Immersion) – how many tons are needed to change the draft by 1 inch • Difference between feet and inches when expressing draft (12 inches = 1 foot) • Converting kips (kilo-pounds) to tons if needed for the vessel’s TPI

💭 Think About

• What information would you need to know about the COASTAL DRILLER (such as its TPI) to relate added weight to a change in draft? • Once you know how many inches the draft changes, how do you convert that into feet and inches to match the answer choices? • Is the added weight likely to make only a small change (a couple of inches) or a large change (several tenths of a foot)? Estimate first before calculating.

✅ Before You Answer

• Be sure you are using the same weight units as the vessel’s TPI (tons vs kips vs pounds) • Carefully convert inches of immersion to feet and inches before comparing with the choices • Check that the change in draft is reasonable for the amount of weight added to a vessel of this type and size
