The DEEP DRILLER at survival draft loads...

The DEEP DRILLER at survival draft loads 2,068.1 long tons of ballast. What is the new draft?

🔍 Key Concepts

• Understanding what survival draft means for a unit like DEEP DRILLER • How to relate long tons of ballast added/removed to a change in draft using a tons-per-inch (TPI) or displacement vs. draft table • Recognizing that survival draft is usually a specific, known draft from the stability booklet or exam data

💭 Think About

• Ask yourself: At survival draft, is ballast being added or removed to reach 2,068.1 long tons? How would that affect the draft (increase or decrease)? • Think about the typical range of drafts for this type of unit. Would a survival draft more likely be shallow, moderate, or very deep? • Consider what information from earlier in the exam/problem (e.g., hydrostatic or loading tables for DEEP DRILLER) you would normally use to connect ballast weight to final draft.

✅ Before You Answer

• Verify whether the question implies you already know the survival draft value from a previous data table or problem statement. • Check that the answer you pick is reasonable for a survival draft of a MODU/rig like DEEP DRILLER (too shallow or too deep should be suspect). • Confirm whether the situation is lightship + ballast or another loading condition, and how that would affect the draft range implied by the choices.
