Question 1 of 29218

The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of the No.7 drill water tank are discharged, what would be the new TCG?

🔍 Key Concepts

• Transverse center of gravity (TCG) and what a negative vs positive value means on the load form • Effect on TCG when you remove (discharge) a weight located port or starboard of centerline • The basic shift formula: shift in G = (weight moved × transverse distance) / displacement

💭 Think About

• On the Sample Load Form, note the original TCG and whether No.7 drill water tank is shown to port, starboard, or on the centerline • When you discharge a tank, is that like adding weight or removing weight at that transverse location? Think about whether G moves toward or away from removed weight • Estimate whether the magnitude of the new TCG should be larger or smaller than the original, based on the tank’s weight compared to total displacement

✅ Before You Answer

• Verify the transverse location of No.7 drill water tank (port, starboard, or centerline) on the load form • Check the weight of the contents in No.7 drill water tank and the total displacement of the COASTAL DRILLER to gauge how big the shift could be • Confirm the sign convention used: which side is positive and which is negative for TCG on that particular load form
