Question 4614 Deck General

The correct answer is A) stronger. The exterior hull plating on a Mobile Offshore Drilling Unit (MODU) is usually stronger than the internal structural plating. This is because the exterior hull plating needs to withstand the external forces and stresses encountered during offshore operations, such as waves, currents, and potential collisions. The stronger exterior plating helps ensure the structural integrity and safety of the MODU. In contrast, the internal structural plating is designed to support the weight of the MODU and its equipment, but does not need to be as thick or strong as the exterior hull plating. The other options are incorrect because: B) thinner is incorrect as the exterior hull plating is typically thicker than the internal structural plating; C) more corrosion resistant is incorrect as the exterior plating may not necessarily be more corrosion resistant than the internal plating; and D) a lower grade steel is incorrect as the exterior plating is generally made of a higher-grade steel to withstand the external forces.
