🔍 Key Concepts

• KG (height of center of gravity) and how it changes when weight is removed from the vessel • Effect on KG when removing weight from a known vertical position (using the moments / ‘GG1 = wd/W’ concept) • Difference between KG and KGL on the Deep Driller stability data sheets

💭 Think About

• How do you calculate the change in KG when you remove a weight located at a certain height above or below the keel? Think about the sign and direction of the shift. • When all mud is dumped, where was that mud located vertically, and how does its removal affect overall KG and therefore KGL? • Which choice is most consistent with the size of the mud weight, its vertical position, and the vessel’s total displacement shown on the sample load form?

✅ Before You Answer

• Verify the total mud weight and its KG (or vertical location) from Sample Load Form #4. • Confirm the vessel’s displacement (W) in that condition before dumping mud. • Use the correct formula for change in KG: GG1 = (w × d) / W, and then relate that change in KG to the change in KGL shown on the Deep Driller forms.
