What is the change in the vertical moments for the DEEP DRILLER if 2.0 feet of ballast is transferred from a full ballast tank 3P to an empty ballast tank 10P?

🔍 Key Concepts

• Effect of transferring weight on vertical moments (VCG – vertical center of gravity) • How to compute change in moment: Moment = Weight × Vertical distance moved • Understanding that transferring ballast between two tanks is like moving a weight from one vertical location to another

💭 Think About

• When you move ballast from tank 3P to tank 10P, is the vertical center of gravity of the vessel moving up or down overall? • Is the total weight of the vessel changing, or just the distribution of that weight? How does that impact total vertical moments? • Which tank (3P or 10P) is higher or lower vertically, and how does that affect the sign (increase or decrease) of the vertical moment?

✅ Before You Answer

• Confirm the vertical distances (KG or vertical centers) of tanks 3P and 10P from the hydrostatic data or capacity plan in the stability booklet for DEEP DRILLER • Calculate the vertical moment removed from 3P and the vertical moment added to 10P separately, then find the net change • Be sure about the direction of movement of the ballast (from which vertical level to which) to decide whether the total vertical moment increases or decreases
