Question 4617 Deck General

The correct answer is D) non-structural. In MODU (Mobile Offshore Drilling Unit) construction, bulkheads in the quarters (living areas) are generally non-structural, meaning they are not intended to provide significant structural support to the vessel. These bulkheads are primarily used for partitioning and defining the interior spaces, rather than serving as critical structural components. The other answer choices are incorrect because: A) continuous bulkheads may be found in other areas of the MODU, but not necessarily in the quarters; B) watertight bulkheads are typically found in the hull and other critical areas to maintain the vessel's integrity, but not necessarily in the quarters; and C) structural bulkheads are used to provide the main support for the MODU's overall structure, but the bulkheads in the quarters are not considered part of the primary structural system.
