🔍 Key Concepts

• Using a tank capacity table for a specific tank on a specific vessel (COASTAL DRILLER) • Converting a sounding (feet and inches) into the exact value needed for the table or for interpolation • Converting volume of liquid in the tank to weight in kips using the correct density or weight per barrel/ft³

💭 Think About

• What is the exact sounding in decimal feet for 8 feet 2 inches, and where does that value fall between the entries in the capacity table for drill water tank #1? • Do you need to interpolate between two table entries, or is 8 feet 2 inches listed directly? If interpolating, how do you find the fraction between the two soundings? • Once you have the volume, what is the correct unit conversion to go from volume of drill water to weight in kips?

✅ Before You Answer

• Make sure you are using the correct tank table: drill water tank #1, not a different tank on the COASTAL DRILLER. • Carefully convert inches to decimal feet and check that you used the correct values when interpolating. • Confirm your unit conversions: barrels or cubic feet to pounds, and then pounds to kips (1 kip = 1,000 lb) before choosing the answer.
