🔍 Key Concepts

• Hydrostatic/trim and stability booklet for the DEEP DRILLER, specifically the tables for P‑tank #1 • Relationship between ullage, volume in the tank, and moment (weight × transverse distance) • Using the correct unit conversions (barrels/tons per inch/foot) that match the booklet

💭 Think About

• How do you use the given ullage to find the amount (weight) of liquid in P‑tank #1 from the tank capacity table in the booklet? • Once you know the weight, how do you obtain the transverse moment—do you calculate it, or is it given directly in the tank table for that specific ullage or corresponding sounding? • Are you sure you are in the correct column/row for P‑tank #1 (port or starboard), and not using data for a different tank or a different reference (soundings vs ullages)?

✅ Before You Answer

• Confirm you are using the correct tank table for P‑tank #1 on the DEEP DRILLER (not centerline or another P‑tank). • Verify you are using ullage, not sounding, and that you have converted it properly if the table is based on sounding instead of ullage. • Double‑check that the moment units in the table match the answer choices (ft‑tons) and that you haven’t mistaken weight for moment or vice versa.
