Question 1 of 27070

The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballast to Survival). What is the new longitudinal location of the center of buoyancy if all the bulk materials are discharged?

🔍 Key Concepts

• Longitudinal center of buoyancy (LCB) and how it shifts when loads are removed • Using moments: how removing a weight (or load) affects the vessel’s overall LCG/LCB position • Reading and comparing data from Sample Load Form #2 (Ballast to Survival) before and after discharge

💭 Think About

• When you discharge bulk materials, does the vessel’s underwater volume (and therefore buoyancy) shift toward or away from where those materials were located? • How would you calculate the new longitudinal position using moments: what information from the load form do you need to sum and what do you divide by to find a new center? • Compare the original LCB position with the new one: should the change be small or large, and in which direction along the vessel’s length?

✅ Before You Answer

• Identify exactly where (longitudinally) each bulk material is located on the sample load form before discharge — note their lever arms. • Calculate (or conceptually track) the change in total longitudinal moment when those materials are removed, and how that changes the overall center. • Verify whether the final LCB should move forward or aft and by roughly how much, then see which option best matches that expected shift.
