Preload tank 22B on the COASTAL DRILLER contains 5.0 feet of preload. It is decided to complete filling the tank. What is the TCG of the added liquid?

🔍 Key Concepts

• Review how to compute the transverse center of gravity (TCG) of added liquid when a tank is only partially filled and then completed to full • Use the tank’s hydrostatic/loading data table for tank 22B on the COASTAL DRILLER to compare TCG at 5.0 ft and at full depth • Remember that the TCG of the added weight is found using a moment balance between initial condition and final condition

💭 Think About

• What information from the tank data do you need at 5.0 feet and at full load to be able to compute the TCG of only the added liquid? • How can you use the relationship: (Total final moment) = (Initial moment) + (Moment of added liquid) to isolate the TCG of the added liquid? • Once you find the TCG of the added liquid, which answer choice is closest to your calculated value, given the usual rounding in loading manuals?

✅ Before You Answer

• Be sure you are using TCG values and volumes for tank 22B at exactly 5.0 ft and at the final full level from the correct COASTAL DRILLER tables • Double-check that you compute the moment of the initial condition and the moment of the final condition before subtracting to find the moment of the added liquid • Confirm you divide the moment of the added liquid by the amount of added weight/volume, not by the total final weight/volume
