Question 1 of 201VawALYe4RduipEwGDmn

The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Weather conditions make it necessary to ballast down to survival draft. It is decided to check the stability at the intermediate draft of 32 feet. If the added ballast has an average VCG of 9.03 feet, what is the new KG?

🔍 Key Concepts

• KG (Height of Center of Gravity) and how it changes when weight is added • Using the combined center of gravity formula when adding weight: new KG based on original displacement, original KG, added weight, and VCG of added weight • Interpreting data from Sample Load Form #1 (Transit) to find original displacement and KG

💭 Think About

• From the Sample Load Form #1 (Transit), what are the original displacement and KG before ballasting? • When you add ballast with a VCG of 9.03 ft, how do you combine the original ship’s center of gravity with the ballast’s center of gravity to get a new KG? Write the formula symbolically first. • After computing the new KG, is the value reasonable? (Should adding low ballast raise or lower KG?)

✅ Before You Answer

• Be sure you are using the correct original displacement and KG from the transit condition on Sample Load Form #1. • Confirm that you are using consistent units (all in long tons and feet). • Before picking an answer, check whether your computed KG moved in the right direction (up or down) based on adding ballast low in the vessel.
