Question 4705 Deck General

The correct answer is A) even and symmetrical variable loading. Structural stress on a MODU (Mobile Offshore Drilling Unit) can be reduced by maintaining even and symmetrical variable loading. This ensures that the weight distribution on the MODU is balanced, minimizing the localized stress on the structure. Uneven or asymmetrical loading can lead to increased stress in certain areas, potentially compromising the structural integrity of the MODU. The other options are not as directly related to reducing structural stress. Increasing the metacentric height (B) affects the stability of the MODU, but does not necessarily reduce structural stress. Lessening the effect of environmental forces (C) is important, but it does not directly address the issue of structural stress. Concentrating heavy consumables locally (D) may not evenly distribute the load, potentially increasing structural stress in certain areas.
