While loaded as shown in the COASTAL DRILLER sample load form 3 (drilling), all of the casing is discharged. What is the change in LCG?

🔍 Key Concepts

• Longitudinal Center of Gravity (LCG) and how it shifts when weights are removed • Using the sample load form 3 (drilling) to find original and final conditions • How removing a weight at a known longitudinal position changes the combined LCG

💭 Think About

• Where was the casing located longitudinally relative to the vessel’s original LCG (forward, aft, or at the same position)? • When you remove that casing weight, does the ship’s LCG move toward or away from the position of the removed weight? • Based on the magnitude of the casing weight and its distance from the original LCG, would you expect a large shift or a very small shift in LCG?

✅ Before You Answer

• From the load form, identify the LCG of the casing and the total displacement and LCG before removal • Recalculate the new total displacement and LCG after setting the casing weight to zero, using the standard LCG moment formula • Compare your numerical result to the choices, paying attention to direction (forward/aft) and order of magnitude (feet vs hundredths of a foot)
