🔍 Key Concepts

• Effect of removing weight high on a vessel or MODU on center of gravity (G) • Relationship between topside weight and stability/righting arm • Difference between center of gravity change and trim/even keel corrections

💭 Think About

• When you remove weight from high up on a structure, in which vertical direction does the center of gravity move? Why? • Does jettisoning weight from topside directly affect free surface of tanks, or mainly the vertical position of G? • Would throwing weight overboard from one side necessarily correct trim/keel, or mainly affect stability characteristics?

✅ Before You Answer

• Sketch a simple side-view of a MODU and mark original G and new G after removing high weight • Recall that stability improves when G moves farther below the center of buoyancy (B) • Confirm whether changing weight distribution on deck directly changes free surface effect in tanks or not
