🔍 Key Concepts

• Vertical moments and VCG (Vertical Center of Gravity) – how weight added or removed affects the vessel’s vertical moments • Relationship: Vertical Moment = Weight × Vertical Distance from a reference (usually baseline or keel) • Effect of discharging ballast (removing weight) from a known height on total vertical moments

💭 Think About

• Think about whether discharging ballast causes the total vertical moments to increase or decrease, and why • Identify what information you would need from the Deep Driller’s data tables to find the vertical distance associated with tank 1P • Once you know the weight and the vertical distance, how would you calculate the change in vertical moments, and what sign (plus or minus) should it have?

✅ Before You Answer

• Confirm whether the tank 1P data in the stability booklet gives a VCG or KG (height above baseline) for the ballast in that tank • Check that you are using the correct distance in feet and the correct weight in long tons with no unit conversion errors • Make sure your final change in vertical moments is labeled as a decrease, since weight is being removed, and that its magnitude matches one of the options
