The DEEP DRILLER is loaded as shown in Sample Load Form #4 (Drilling). What would be the new sum of longitudinal moments for the Stores & Supplies (Table 6) if paint weighing 3.48 tons is added to the paint locker?
• How to calculate a new longitudinal moment when weight is added to a compartment • Using the LCG (longitudinal center of gravity) or station of the paint locker from the load form • Updating the Table 6 Stores & Supplies total by combining old moments with the new item
• From Sample Load Form #4, determine the existing total longitudinal moment for Stores & Supplies in Table 6 before adding the paint. • Find the longitudinal position (lever arm) of the paint locker used for Stores & Supplies and calculate the moment created by the new paint weight. • Think about whether you should add only the new paint’s moment or somehow re‑calculate all items in Table 6 from scratch.
• Verify the weight of paint (3.48 tons) is used exactly as given with no rounding until the last step. • Verify the correct longitudinal distance (in feet) for the paint locker from the load form before multiplying by the weight. • After adding the new paint moment to the existing total, check that your answer is close to one of the listed choices and that your units are in foot‑tons.
