Question 4608 Deck General

The correct answer is D) At the bottom of the tank. On a MODU (Mobile Offshore Drilling Unit), the thicker plating is typically found at the bottom of integral tanks due to the increased hydrostatic pressure at the lower part of the tank. The bottom of the tank experiences the highest pressure from the weight of the liquid stored, so it requires thicker plating to withstand this pressure. The other options (A, B, and C) are incorrect because the thicker plating is not typically found on the outside, center, or top of the tank, respectively, as these areas do not experience the same level of hydrostatic pressure as the bottom of the tank.
