🔍 Key Concepts

• Trim and stability concepts: how removing weight affects a vessel’s draft • Relationship between displacement (kips) and change in draft using TPI (tons per inch immersion) or equivalent • Unit conversions between feet and inches when adjusting draft

💭 Think About

• When weight is discharged, does the vessel sink deeper or rise in the water? How does that affect the draft numerically? • How would you use the vessel’s TPI (or similar constant) to relate 216.43 kips of weight change to a change in draft? What does that tell you about whether the draft change should be large or small? • After finding the approximate change in draft, which answer choice best matches your result once you convert between feet and inches?

✅ Before You Answer

• Confirm the direction of draft change when weight is removed (less displacement). • Estimate whether 216.43 kips is a relatively large or small change for a vessel like COASTAL DRILLER and whether the draft should change by several inches or several feet. • Double-check feet–inches conversions (e.g., 0.3 ft, 0.4 ft, etc.) into inches so your final draft matches one of the options correctly.
