You have 4 containers of rig supplies each measuring 8'L by 8'B by 8'H and weighing 1.2 tons 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.

Correct Answer: Option B — 1.68 feet

Calculating deck cargo moments and applying hydrostatic limitations from stability reference documents establishes that the remaining cargo vertical center of gravity must not exceed 1.68 feet to maintain required intact stability criteria when fully loaded with rig water.
