A MODU displacing 29,500 long tons has a KG of 60 feet. A weight of 500 long tons is added at a VCG of 150 feet. What is the change in KG?

🔍 Key Concepts

• KG (height of center of gravity) and how adding a weight at a different height affects it • The shift of G formula for adding weights: ( \text{New KG} = \frac{W_1 \times KG_1 + W_2 \times KG_2}{W_1 + W_2} \) • The relationship between displacement, added weight, and change in KG

💭 Think About

• First, find the total displacement after the weight is added. How does that change from the original displacement? • Think about the moment each weight creates: displacement × KG. How do you combine the moments of the original vessel and the added weight? • After you find the new KG, compare it to the original 60 feet. How much did it rise (and in which direction)?

✅ Before You Answer

• Carefully convert and keep track of all weights in long tons and all heights in feet. • Make sure you compute the total moment before (original displacement × 60 ft) and moment of added weight (500 LT × 150 ft). • Verify your final step: subtract new KG − old KG to get the change, and confirm it matches one of the choices in both magnitude and direction (upward).
