The DEEP DRILLER, at a draft of 45 feet and total vertical moments of 981,567 ft-long tons, floods 2068.7 long tons of sea water through the overboard discharge into tanks 3 and 8 on both sides. The VCG of the added ballast is 7.22 feet. The shift in the height of the center of gravity is __________.

🔍 Key Concepts

• Vertical center of gravity (KG) and how it is calculated from total vertical moments and displacement • Effect of adding weight at a known VCG on total vertical moments and KG • How to find the change in KG (shift in G) before and after ballasting

💭 Think About

• From the stability data for 45 feet draft, determine the vessel's displacement, then compute the original KG using total vertical moments and displacement. • Calculate the additional vertical moments from the ballast (weight × its VCG) and the new total displacement, then recompute KG. • Compare the new KG with the original KG to find the shift in the height of G, and then match this change (not the final KG itself) to the closest answer choice.

✅ Before You Answer

• Be sure you are using the correct displacement at 45 feet draft from the stability data, not a made‑up or assumed value. • Confirm that you add the ballast weight both to the total vertical moments (as w × VCG_added) and to the displacement (in long tons). • Double‑check that the answer you choose is the change in KG (ΔKG), not the absolute value of KG after ballasting.
