Question 4669 Deck General

The correct answer is A) using fuel from a pressed fuel tank. When fuel is drawn from a pressed fuel tank, the center of gravity of the mobile offshore drilling unit (MODU) will rise. This is because the fuel in a pressed tank is stored at a higher level compared to an unpressed tank, and as the fuel is consumed, the center of gravity of the MODU will shift upwards, resulting in a virtual rise in the center of gravity. The other options are incorrect because: B) Emptying a partially filled tank would cause the center of gravity to lower, not rise. C) Transferring pipe from the setback area to the pipe rack would not affect the center of gravity of the MODU. D) Filling a partially filled tank would cause the center of gravity to lower, not rise.
