🔍 Key Concepts

• Longitudinal Center of Gravity (LCG) and how it shifts when weight is added/removed • Moment = Weight × Distance and how to use total longitudinal moments to find a new LCG • Sign convention: which direction is considered positive/negative for LCG changes on the DEEP DRILLER load form

💭 Think About

• Identify the weight and longitudinal position (LCG) of all casing before it is discharged, then determine the total longitudinal moment associated with that casing • Think about whether removing this casing weight from its location will move the vessel’s LCG forward or aft relative to the original LCG • Compare the magnitude of the LCG shift you calculate with the answer choices, paying close attention to both the size and the sign (+ or -)

✅ Before You Answer

• Confirm the reference point used for LCG on the Sample Load Form #3 (is it from amidships, AP, FP, or another datum?) • Verify the sign convention: does a positive LCG mean forward or aft on this particular load form? • Re‑check your total weight and total longitudinal moments before and after removing the casing to ensure you didn’t miss any casing items or positions
