Question 1 of 2066636eec28f7522a1c51bef7

You have 50 containers of ships stores each measuring 6'L by 4'B by 3'H and weighing 0.4 ton each. Each container is stowed on deck. What is the maximum VCG permitted of the remaining cargo if you are carrying rig water and load to maximum capacity? See illustration D037DG below.

🔍 Key Concepts

• Read restriction 3 on D037DG about the maximum height of the center of gravity of deck cargo above the main deck. • Read restriction 4 on D037DG about the maximum deck cargo allowed when carrying rig water. • Use the idea of combined center of gravity: total moment divided by total weight must not exceed the allowed height above deck.

💭 Think About

• When you are carrying rig water, what is the maximum total deck cargo weight allowed by the letter, and how much of that is already used by the 50 containers? • If each container is 3 ft high and sitting on deck, what is the height of its own vertical center of gravity above the deck? • Write an equation for the combined VCG of the existing containers plus the remaining cargo, set it equal to the 2.0 ft limit from the letter, and solve for the unknown VCG of the remaining cargo.

✅ Before You Answer

• Confirm from the letter that the deck‑cargo CG must not exceed 2.0 ft above the main deck. • Confirm from the letter that when carrying rig water, the maximum deck cargo weight is 35 long tons, with no other below‑deck cargo or ballast. • Be sure to use moments (weight × VCG) for each part of the deck cargo and divide by the total deck‑cargo weight to find the combined VCG.
