🔍 Key Concepts

• Use the COASTAL DRILLER tank capacity/sounding table for Drill Water Tank #1, not a generic formula • Convert the given weight in kips to long tons or pounds as shown in the stability data booklet notes • Remember that tank soundings are found by matching weight (or volume) to the corresponding sounding in the table, considering the fluid’s specific gravity if indicated

💭 Think About

• What unit does the Drill Water Tank #1 table use for the vertical column (weight or volume), and how does that compare with the given 388.32 kips? • Is there a note on the tank table about a specific gravity or density for drill water that you must apply before using the table? • After you match the correct weight (or corrected weight) to the table, which sounding value (in feet) lines up with that entry?

✅ Before You Answer

• Confirm the unit conversion: 1 kip = 1000 lb, and how to change that to long tons if the table uses tons • Verify whether the table is based on seawater (SG 1.025), freshwater (SG 1.0), or drill water (other SG) and adjust the weight/volume if required • Make sure you are reading the correct tank (Drill Water Tank #1) and interpolating only if the exact weight is not listed in the table
