The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the shift in TCG if 100.76 long tons of ballast are added to Ballast Tank #8S to replace the discharge of all bulk materials?

🔍 Key Concepts

• Transverse Center of Gravity (TCG) and how adding weight off the centerline affects it • Using the moment = weight × transverse distance relationship to find the new TCG • How to correctly read tank transverse locations from Sample Load Form #2 (Ballasting to Survival)

💭 Think About

• How does adding ballast to a starboard tank affect the vessel’s TCG compared to its original value on the load form? • What transverse distance (from centerline) should you use for Ballast Tank #8S, and how does that distance influence the size of the TCG shift? • After calculating the new total transverse moment and dividing by the new displacement, where will the new TCG be relative to the centerline and the original TCG?

✅ Before You Answer

• Be sure you are using the correct transverse arm for Ballast Tank #8S (from the actual load form). • Confirm you are using long tons consistently in all weight and moment calculations. • Double‑check that you subtract the original total transverse moments from the new total to get the net TCG shift, and note clearly whether it is to port or starboard.
