The COASTAL DRILLER is loaded as shown in Sample Load Form Number 3 (Rig Move). What would be the new sum of vertical moments for the liquid variables if the entire contents of tank 20 are transferred to tank 13?

Correct Answer: Option B — 2,244 ft-kips

Liquid variable moment calculations involve multiplying the transferred fluid weight by its new vertical distance from the baseline. Transferring the complete contents of tank 20 to tank 13 alters the vertical moment summation, resulting in a new liquid variable vertical moment of 2,244 ft-kips.
