You have 650 tons of below deck tonnage including liquid mud. Your existing deck cargo is 140 tons with a VCG above the deck of 2.5 feet. What is the maximum additional cargo tonnage you are permitted to load? See illustration D036DG below.
⢠Use the loading diagram D036DG: relate below deck tonnage on the Xâaxis to total deck cargo on the Yâaxis ⢠Remember the Yâaxis shows total deck cargo (existing + additional), not just the added load ⢠Check the maximum deck cargo VCG of 3.0 ft above deck against the given 2.5 ft VCG
⢠At 650 tons of below deck tonnage, where does the vertical line from the Xâaxis intersect the safeâloading curve, and what deckâcargo value does that correspond to? ⢠How do you turn that maximum allowable deckâcargo value into the extra tonnage you can still load when you already have 140 tons on deck? ⢠Does the given VCG of the deck cargo create any further restriction, or is it already within the allowed limit on the diagramâs instructions?
⢠On the diagram, be sure you are reading long tons of deck cargo on the Yâaxis at exactly 650 tons below deck on the Xâaxis ⢠Confirm you are using total deck cargo = existing + additional, not just plotting the additional load alone ⢠Verify that the 2.5 ft VCG is less than the 3.0 ft maximum in the instructions so no extra reduction in allowable tonnage is needed
