You have 480 tons of below deck tonnage...

Question 1 of 2707066636eec28f7522a1c51bef6

You have 480 tons of below deck tonnage including liquid mud. Your existing deck cargo is 200 tons with a VCG above the deck of 2.8 feet. What is the maximum additional cargo tonnage you are permitted to load? See illustration D036DG below.

🔍 Key Concepts

• Use the loading diagram D036DG: vertical line from total below-deck tonnage and horizontal line from total deck cargo to check if you’re in the SAFE or UNSAFE region. • Remember that the maximum deck cargo VCG (vertical center of gravity) allowed is 3.0 ft above the deck, and your present deck cargo VCG is 2.8 ft above deck. • Your existing 200 tons of deck cargo plus any added deck cargo must stay at or below the limiting curve for 480 tons below deck tonnage.

💭 Think About

• On the graph, what happens when you draw a vertical line up from 480 tons below deck? At about what "above deck cargo" value does that line meet the boundary curve between SAFE and UNSAFE loading? • Once you have the maximum permissible deck cargo from the diagram at 480 tons below deck, how do you use your existing 200 tons of deck cargo to find how much more you may load? • Does adding more deck cargo at the same VCG of 2.8 ft ever violate the 3.0 ft maximum VCG requirement, or is the limiting factor here only the curve on the loading diagram?

✅ Before You Answer

• Be sure you are reading long tons on both axes of the diagram; don’t mix units. • Confirm that the 480 tons already includes all below-deck weights, including the liquid mud, before you go to the graph. • Double‑check that your point representing the final loading condition (480 below deck, total deck cargo) falls on or just below the SAFE/UNSAFE curve—not above it.
